AHCI or RAID for new install?

Q: AHCI or RAID for new install?

I?m going to reinstall Windows 7 on an SSD (120 MB) I just bought. I know I need to set the bios to AHCI mode for the SSD. I also have a RAID (2 x 250 MB 7200rpm) array I would like to use for data storage. I was going to install windows with only the SSD connected and then connect the RAID array. My problem is I can only set the SATA ports on AHCI or RAID. What do I set the bios on to have both installed? The MB is an Asrock 760GM-GS3.

Preferred Solution: AHCI or RAID for new install?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello,


Is there anyone able to help me with changing the SATA Controller mode from RAID to AHCI (in BIOS) after install without having to re-install Windows 8?


I am suspecting Intel RAID controller to be causing some problems with system stability and would like to move to software RAID (storage space) in Windows 8 and give it a try.  When I change the BIOS settings from RAID to AHCI in the SATA controller
mode, Windows 8 wont boot and running a system repair will not do neither.


I found this KB, but it is for Windows 7 and wont run on Windows 8? Anything similar for Windows 8?

http://support.microsoft.com/kb/922976



A bit of details about the system:

System: Windows 8 pro 64
Primary HD (OS Only + bitlocker): Intel SSD 520 ? 240 Gb
Data HD (user files +bit locker): 2x WD RED 2T running in RAID 1
Motherboard RAID Controller: Intel DP55WB -  latest BIOS and Intel RST 11.6?.1030 driver


Thank you.

GIGABYTE - Motherboard - Socket 1155 - GA-P61-S3 (rev. 2.0)

Ive installed the rest of the drivers provided by manufacturer except the SATA RAID/AHCI ones.The Intel Rapid Storage Technology gave me an error that I dont meet the system requirements so I no longer insisted with the others. Hmmm, why are these listed for my motherboard then? or what exactly are they?
I was thinking I need to instal first the "Intel SATA Preinstall driver(For AHCI / RAID Mode) Note: Press F6 during Windows setup to read from floppy" -the last item on the list -but dont know how , there are just some "sytem files, security catalog, setup information". You can fast download and checked them.

So I picked up a pair of Corsair Force 120Gb SSD drives and set them up in RAID 0. Figured I could just slap them in, load the AMD RAID drivers then do a clean install of Win 7. Which I?ve done and everything seems to be working fine. Now reading about the performance benefits when setting your drive controller to AHCI within Windows. My question is, can I still set the controller to AHCI within Windows even though I?ve configured the drives in a RAID 0? The BIOS only allows 3 choices, IDE, RAID and AHCI. It?s a Asus M4A7TD EVO Motherboard (AMD 870/SB 850 chipset)

A:Raid 0 + AHCI?

Thanks for the reply but still didn?t really answer my question. My BIOS is set to RAID 0 for my 2 SSD. I assumed that setting this to AHCI within the BIOS I would lose the RAID and therefor have to reinstall Windows. However, the many SSD tweaks that I?ve read (SSD Tweaks and Optimizations in Windows 7) state to set your IDE ATA/ATAPI Controller within device manager to AHCI. Would this not conflict with what the BIOS is set at?

While experimenting with a USB bootable Macrium Restore thumb drive I created, I was looking in my Bios and noticed the SATA controller was set to Raid. I have only one internal HD.

I changed it to AHCI and booted up, got a notice that new drivers were being installed and rebooted.

The computer seems to be running the same. Wondering why HP had it set to Raid.

So what is the difference between the two settings?

Hi.
I have just purchased a Dell XPS 15 Laptop with a single 512gb SSD.
I am wanting to clean install Windows 10 but am unsure whether to place the BIOS in RAID or AHCI?
I have heard the read/write SSD speeds are similar once in windows. Would one of these interfaces perform better boot times? Are there any other advantages?
Any advice would be great.

A:AHCI or RAID

I would go with what your notebook came with, unless you have a particular reason like adding a 2nd SSD 512GB and wanting to RAID 0 them? Otherwise leave the BIOS/UEFI alone

Whats the difference because, i dont know if this is a issue but when ever i want to install windows 7 i have to set my sata controller to ahci instead of its default settings which is RAID, why do i have to do that?

A:Raid vs ahci?

Raid requires more than one disk. RAID is a collection of disks that provide data redundancy in case one the disks fails. AHCI is a SATA disk contoller interface that provides an advanced (compared to IDE) disk protocol. AHCI is a protocol that is used at the disk level. RAID is a protocol for redundancy across multiple disks drives.

I have a friends HP system I'm fixing for him. His hard drive died, totally inaccessible (750GB SATA 3 Seagate).

I ordered the recovery DVD and a new hard drive.

In BIOS, the SATA controller can be set to Raid, AHCI or IDE. My question is, which is the right one to use. It was set to Raid but during one of several attempts to use the Recovery partition, I switched that to AHCI as I see no point in setting it to Raid with only a single drive. Is this the best setting to use?

A:Raid, AHCI or IDE

Hello.



Yes, AHCI is the best option for an install to a single SATA HDD.



For anyone that doesn't get it set before the install, there's always this tutorial at the link below.

I recently bought 2 120GB OCZ Vertex 2 SSDs, a new CPU heatsink, and 2 new video cards (5850s). I was running my Windows 7 64 on 2 WD velociraptors in RAID0 prior to rebuilding my system. I never had any issue with Windows installation. I tried setting up my system to where my SSDs would be in RAID0 and so would my Velociraptors and when I go to install Windows it prompts me with a message telling me that it cannot find DVD Drive drivers. So I tried installing in AHCI mode but when I go to install, Windows tells me it cannot create a new partition or locate an existing partion. I'm able to install in IDE mode in my BIOS, but that's it. Any suggestions?

A:Ahci & raid

You'd need to set the SATA controller to RAID to use that. Otherwise, use only one HD set to AHCI mode.

A:Going from AHCI to RAID

What I have done in the past is to boot with the system drive connected to one of the non Intel controllers.

If it will boot, shut down and set the Intel controller to Raid in the BIOS..

Reboot with the system disk still connected to the non Intel controller. I usually keep one of my other drives connected to the Intel controller so I can see if it is visible in Windows after it finds the Raid driver.

The system should now load the proper RAID drivers. Now move the system disk back to the Intel controller.

1st of you do not get 7.5K RPM HDD's they are 7.2K RPM HDD's.

Windows index is meaningless in real life, under Windows 7 5.9 is the fastest you can get for ANY Mechanical HDD period.

The higher scores must detect a SSD before it will even go by 5.9.

You can score 5.9 with any modern single fast HDD and the same for 2x10K HDD's in Raid 0.

I would be going by overall how the PC feels not Windows crappy score.

Hi all,

My current 7100 RC installation sits on two hdd's in RAID 0, provided by the onboard controller; in this case an Intel IHC10R.

I switched the disc mode in BIOS to AHCI; the intent was to reformat and re-install a BSD based system on the second drive, 7 back on the first, and dual boot.

Now, here's the interesting part, I missed the boot prompt and it went into loading windows again, however, it loaded straight into Windows 7.

So although I took the boot order off raid and selected AHCI, it still boots fine!

I don't really understand what went on, but i'd love to know, so I'd like to ask you guys if you can shed any light on this.

you're on your own with that one, maybe someone else can answer that one. I don't know why it's still booting after that. lol

A:Switch from AHCI to RAID

Never had to do any kind of registry changes to do Raid 1 before.

You do realize that running a Raid is not about adding storage. It is about being able to mirror a copy across multiple drives. That way if you lose one drive, you are not losing all files.

Basically for Redundancy and speed if you have a fast enough Raid card.

A:SATA, AHCI, Raid compatability

As far as activation, I would think you will have no problems. It may take a phone call to activate, but that is normally no big deal. If you are running Windows 7 Professional or Ultimate, you can run Windows XP mode where all of your programs from XP will install and run. Windows XP Mode - Install and Setup

Failing that you can install XP in a Virtual Machine and run it that way without having to dual boot or swap hard drives. This may help. It is how to set up Linux in a Virtual Machine with VMware player (free). It will work the same way to run XP in. (Windows XP Mode - Install and Setup) I have XP running in a VM now. One of those options should solve most of your problems.

As far as #1, it will not matter. When you set up raid, you will have to do a clean install anyway, no matter what your sata controller is set to. Raid is a striped array of disks and has to be set up and clean installed. There is really almost no reason to run raid on a home computer, and I would recommend against it. If it is speed you want, get a SSD to run your OS and programs on.

Hello!
I have rather fresh m7510 with two SSD's. Primary, where OS was installed is on the factory, came with the system, another 850 EVO was added later. I have installed Samsung Magician to look at my drives. It does recognize the latter, but tell it does not perform optimum because AHCI mode is disabled in BIOS. Yes, I have tried change to 0 the Start value for msahci, iastorv, atapi, no luck.
So question #1, what is right way to get AHCI in this system. OS is Windows 7 64-bit.
The second question is that most of software recognized that primary drive as

while Intel RST tells it is
PM951 NVMe SAMSUNG 256GB
So I am curious about those character scrambling and interested, how to get it under Samsung Magician control.
Thanks in advance

A:m7510 primary SSD RAID to AHCI

Samsung Magician works only with retail Samsung drives - it won't work with the OEM 951 drive.
You don't want AHCI for an NVMe drive - the drive runs in native PCIe mode, not AHCI.

Evening all,
In the last couple of months, I decided to upgrade the stock HDD to a Samsung SSD. I used to Samsung Migration software which cloned the HDD to the SSD, swapped the drives over and everything works fine. 
I noticed in the Samsung Magician tool that that AHCI was disabled and one should enable it for better performance with their SSD. I've gone into the BIOS and changed the setting from RAID to AHCI and again everything works fine however the Magician tool is still saying that the AHCI is disabled. 
I've tried several methods including this however I can't seem to get it to work. When I switched the mode in the BIOS, I never received any errors, Windows booted correctly so am confused. 
Current system is:
OptiPlex 7040, WIN 10 Pro, Samsung 850 SSD connected to SATA0 (where old stock HDD was connected). 
Any help/ advise would be greatly appreciated.

Hello
Motherboard: Asus P7P55D-E Pro
Windows 7 64bit
4 Hard Drives, 1 is boot drive (C), 1 is non-RAID and 2 set up as RAID 1

I am about to replace my Boot drive with a Crucial M550 SSD, by cloning the current drive to the SSD. This appeared a fairly straight forward procedure until reading of the problems associated with running in AHCI mode. I've seen the tutorial and the need to modify the registry to allow installation of AHCI drivers.

Because I have RAID 1, the Intel P55 chipset SATA is set to RAID in the BIOS. I'm presuming that if I were to change to AHCI the RAID would be lost and the PC would likely not boot at all.

If possible could you tell me the best procedure to follow to set up my SSD with my current set up. I'd prefer to avoid fresh re-install and clone if possible.

Thanks for any help.

A:AHCI and Installing SSD on Mirror RAID 1 Set Up

If you have RAID set up with the same controller that the SSD will use, the RAID drivers have the same functions as the AHCI drivers. You do not need to change to ACHI.

Cloning or using an image of the operating system to the SSD should work just fine.

OK I'm stumped. Currently using Onboard RAID1 which is just a pair of 1TB SATA drives that boots into windows 8.1. SATA BIOS mode is set to RAID.

I need want to switch the onboard SATA mode to AHCI so I can boot to SSD, instead.

I'm sure some have tried this: If you just clone the RAID partition as it sits on to the SSD, it will not boot the SSD when the SATA Bios mode is set to AHCI.

So, besides a bare-metal reinstall, how do move my Win8.1 installation on to the SSD so that when its all done the SSD will boot into windows and the SATA Bios is in AHCI mode? I'm not opposed to purchasing software like Macrium or Acronis if any of those can do the job.

It seems like anyone using onboard RAID would have run into this problem after purchasing an SSD.

A:Migrating from RAID to SSD and switching to AHCI

If you wish, you could try:
Open Admin command prompt: bcdedit /set {current} safeboot minimal
Restart to BIOS and set to AHCIRestart. Windows will boot into safe mode and will update the driver.Open Admin command prompt: bcdedit /deletevalue {current} safebootShutdown the PC and disconnect 1 disk.Restart to boot Windows Normally.If goes well, use Macrium Reflect Free to clone your SSD.
Hope this helps !!!

My dell xps 15 9550 currently has my works enterprise build win 10 on it. Although to get it to boot afterwards it had to be set to AHCI mode vs the factory config RAID. Is there a way to install through pxe and support RAID on the 9550? Are 9550s set to RAID to take advantage of the newer NVMe? I did notice some differences on the benchmarks I did under AHCI and RAID.

I recently upgraded to an SSD. I moved windows 7 over to the new SSD and re-aligned the partition properly

The drive setup is as follows:
2x 500GB WD Black drives in RAID 0
1x 120GB ADATA S510 SSD

In BIOS, RAID mode is enabled. You cannot enable RAID for one pair of drives and AHCI separately. I was assuming disks that are not part of the logical RAID volumes would be set to AHCI automatically. I have enabled NCQ in AMD RaidExpert for the SSD.

WEI is 5.9 for the primary disk. The primary disk is the SSD.

Other strange behanivour is that the RAID array and the SSD both appear as SCSI devices in device manager, and Windows won't accept the ahci drivers from ECS.

Below is the benchmark showing poor performance.

My Computer Configuration:
(1) 128GB Solid State Drive (windows os)

Here is the MYSTERY:
I am currently booting to my ssd in ACHI Mode.
yet the 4 hard drives show up as a single hard drive with a capacity of 2TB in explorer.

The Question is:
are the 4 hard drives actually working in a raid 1+0 configuration?
Is this even possible in AHCI Mode?
if this is not possible, then what is happening?

(other details)
when I change the Sata configuration to Raid mode and try to boot to the SSD i get this error message:

Status:0xc000000f
Info: the boot selection failed because a required device is inaccessible

A:Can a Raid 1+0 configuration work in AHCI mode?

4 hard drives in a raid 10 will show up as 2TB. It is composed as follows:

2 pairs of mirrored (raid 1) disk with a raid 0 stripe across the disks. Each mirrored pair is 1TB and you stripe across two of them giving you 2 TB.

Yes, it is probably working.

AHCI or IDE mode should not matter. Are you setting the SSD device to raid mode? If so, that is the source of your error - you need at least two drives to do any type of raid.

How did you go about doing this reinstall... did it come with a restore CD that you followed or did you manually restore it. Also it seems as if you have a RAID setup... being a proprietary setup I'm sure this driver can be found on one of your cds or even on your system if you've done the dell restore.

Another option I'd like you to check for if you could when your system boots hit the delete key and go into your bios settings and search for any type of raid options and let us know what they say.

OK being the impatient type I went ahead and did it and everything is fine after drivers were installed and reboot was required...in each of the 4 boot OS's. It appears to be much faster although my WEI hasn't improved. (I know 5.9 is the max in Vista but was hoping for 7.6 in Win 7 and didn't achieve it....still 5.9 for data transfer).

Anyway everything is fine except now I get the following right before the OS comes up....

"CD_ROM Boot Priority (xxsec) - no medium"

The bit in brackets isn't always there.

My boot priority in the BIOS is 1: my 1st DVD Burner 2: my 1st HDD and 3: Disabled

I've researched online and apart from removing the optical drive from the boot sequence which I've never needed to do in the past, I can't see any settings that I can alter to get rid of that.

Ideas anyone?

...this time I'll have to patient....;-)

Edit: made optical drive 2nd boot device and now I don't get it. It still shouldn't happen, however as I shouldn't have had to do that.

Not sure if this has any bearing...in the BIOS I now have two drive timeout settings...one for IDE and one for AHCI, does that have any bearing? (Both default 35sec)

While dealing with another issue, I've been told that I should switch my SATA mode from RAID to AHCI. I do not have a RAID array and don't plan to. However, I've been told that I would need drivers for this, and I'm not sure if my Windows installation has them or not. I don't want to switch modes only to boot Windows and have it corrupted or god-knows-what. So could someone tell me if it's possible to just switch? Or should I check for drivers first?

Bad choice. RAID requires its own format and thus the BSOD. You will be luck if reversing the action will correct it AND still have data on it.

I have an Asus M4N78 PRO.

There are 6 Sata connectors but 2 support AHCI and RAID mode only. (4 red and 2 black)

I have 3 harddrives and 1 DVD connected in the 4 red ports.

Maybe I'm going to buy a SSD to speed up my PC Is it possible to use one of the black sata ports if I enable AHCI. (I don't want RAID, just want to use it like the others SATA ports).

Then should I put my DVD or a harddrive in the black port?

A:SATA that support AHCI and RAID mode only

If you enable AHCI, I suppose that SATA ports 5 and 6 will behave like the other four SATA ports. I see no indication in the M4N78 PRO manual that ports 5 and 6 are on a third-party controller.

On my own Asus motherboard, I'm using AHCI mode. An SSD, a HD, and two optical drives (all SATA) work without problems.

I don't know how easy it is to switch to AHCI mode without re-installing windows with your nVidia chipset. It's not difficult with Microsoft drivers:

A:W540 SATA Option (RAID or AHCI) gone after BIOS up...

Did you order your system as RAID model?  W540 does not come with RAID by default.  Lenovo has to license RAID option ROM (costs $) so it is only provided if you order RAID model from Lenovo.  As far I as I know, the only RAID model in Europe is 20BG001Sxx.  And your 20BG001Cxx model came with only 1 disk.  If I am wrong about this, please let me know.
 
I believe there was a bug in 1.05 that mistakenly enabled RAID on some non-RAID models.  The bug was fixed in 2.05, so unless you really have a RAID model W540, then RAID would become properly disabled on your system.

After a few tests, I have discovered that I am only getting read speeds of 650 and write speeds of 300 using Crystal Disk - with the data at default and 0 fill.  Should the read speed not be in the region of 1500?
I believe it's using the standard windows 10 driver.
I see in the BIOS that it's in RAID mode.  Could I simply change this to AHCI without affect the current installation?  Would this increase the speed?
Is there anything else I haven't taken into account?

I wanted to be able to hot swap drives, on a Gigabyte GA-Z97-GAMING 3 M/B. Seems the Gigagbyte BIOS has 3 SATA MODE SELECTION options:
IDE, AHCI and RAID. It was set to RAID, which makes sense as the D drive is a pair of matched SATA III drives in a BIOS (software) RAID 1 pairing. C drive is an SSD with the OS on it. However this option doesn't seem to allow hot swapping, even though all drives are set in the BIOS with hot swapping enabled.
Setting the SATA MODE SELECTION parameter to AHCI doesn't allow booting, and I am afraid of enabling AHCI in the registry in case "something bad happens" to the RAID. What will happen if I both set AHCI in the BIOS and set the Win 7 64 bit registry for AHCI? Will the RAID1 Intel Rapid Storage Technology software RAID 1 pairing still work, and will I then have hot swappable drives? Thanks.

A:BIOS, RAID 1 and AHCI hot swappable drives question

Edit: Putting the edit in the beginning, but do read till the end please. You have a separate controller named Marvell? 88SE9172 chip, try setting this as AHCI in BIOS and attach the drives you want to hot-swap to GSATA3 ports 6-7(grey ports?), see if it works. Maybe you wont have to change to AHCI on your Intel chipset after all.

Hey, I have an older AMD Gigabyte board but things may be similar. I will share my experience.

First of all, in BIOS I have 3 different sets of options for IDE/RAID/AHCI. Namely, E-Sata ports (x2 SATAII), GSata (x2,SATAII) and OnChip SATA (this is the SB850 SATA ports,x6 SATAIII). E-Sata and GSata are both controlled by Jmicron chipset.

When I installed current OS a month ago on my new SSD, I installed with OnChip SATA mode set as RAID as I had 2x1TB BIOS raid0 and 2x640GB BIOS raid0 that I didn't want to break. The RAID option in theory is just a subset of AHCI and should have the same functionality. However, Samsung Magician program for the SSD had problems recognizing the SSD properly. So I had to change to AHCI.

You can definitely change the registry to load msahci(and IAStorV on intel?) on startup, it is just another driver to be loaded, OS will continue to use RAID drivers as long as BIOS is set to RAID. However, you will lose your BIOS raid once you switch to AHCI in BIOS, they will be back if you change back to RAID once again (just don't do anything to them in windows ). I backed up my data and set-up a new windows raid0 in disk management and it is working alright atm. So losing your BIOS software raid is not that much of a problem imho.

Now the interesting part is, although OnChip SATA ports are set for AHCI, non of the drives attached to these ports are hot-pluggable. They simply don't show in Safely Remove Hardware. Not that I want these show as removable mind you.

For hot-plug ability, I use E-Sata ports which are set to AHCI as well and had to install the corresponding JMicron drivers. The HD I use for backup purposes is connected to the PC with a SATA-to-ESata data cable and I have an adaptor that can supply 12V+5V 2Amps that has a molex ending, which in turn has a molex to sata power converter. I can hot-plug this disk and just use safely remove hardware like any usb stick/hdd. Now, this may not be what you are looking for, I just wanted to show you even though both chips are AHCI one of them doesn't list drives as hot-pluggable and the other one is.

The above setup is working alright for me so I have not looked into it further but there may be one other option that you can try. 2 weeks ago I had to work on a friend's laptop and his internal drive was showing as removable and I had to do a registry edit to mark it as internal. Perhaps the reverse can also be done?

My internal SATA device appears in Devices and Printers and in the - Microsoft Community

Also, keep in mind that when 2 drives are connected to the same power cable, if you hot-swap one drive it may kill the power to the other drive that is supposed to be keep working.

By the way, you didn't mention why you want hot-swap. Do you have some other drives for backup? You can't hot swap the OS or raid drives anyway.

Hopefully someone more knowledgable with your board will come along and answer proper.

A:Will my Windows Backup work when I go from RAID to standard AHCI?

Most likely you would need to do a repair install after the restore so you could add the drive controllers driver.

You do understand that with raid0 if you lose either drive you are done? Raid0 has no fault tolerance.

A:New RAID Array and Clean Install Win7HP-Help with RAID Driver Install

The pre-install driver will allow setup to install the files correcty on the RAID array this is offered for XP only.

When you have created the RAID array in the BIOS Utility and you launch the windows 7 setup does it show the new array as a possible install location? If so there is no need for a pre-install driver (Win7 supports a variety of RAID setup out of the box).

If you do need a pre-install driver, you have not been offered one for Win7/Vista on the Manufacturers website. The only solution to this I have found is to Download "7lite/Nlite" and build the "post install" driver into the win7 image then burn a new disk (or burn to USB pen for faster install).

Hope this helps.

A:Switching BIOS SATA RAID/AHCI setting causes BSOD at Windows Start

This is a hard one. As I'm sure you know, there should be no difference (to Windows) for RAID vs AHCI. It is normally the same driver, and the same registry setting.

So here is my WAG: maybe you need to have all 3 hard drives connected to break the RAID and change to AHCI.

Once completed, you would then remove the extra drive. Hopefully you have not formatted or changed that drive at all.

A company I do work for had a system come in configured with a single drive, and the BIOS was configured with RAID. The system was upgraded to a Samsung SSD, but the Samsung Magician software commented drive was not set for AHCI. A quick change in the

A:Convert AHCI mode to RAID mode without re-installing

On that board, to get full Windows 8 Secure Boot, you have to Disable the CSM. I know it shows "On", but it will show that until you select Other OS in the Secure Boot section. If you have a Video card installed, such as a GTX XXX, it may not yet be Secure Boot capable and will cause the system to abort the boot and put you back in the bios, when the full Secure Boot is in place.

Have you looked into using Storage Spaces as opposed to RAID? There have been some comments about it is not as stable as RAID, but I have no personal info. Maybe some others will have some information.

If you want to change your system to RAID, it can be dangerous, so backup everything you can, and remember, if it doesn't work, set it back to AHCI.

This is not recommend for Windows 7, just in case anyone wanted to try.

When in Windows 8, open msconfig.exe and set the Safe Boot check box on the Boot tab.

Restart your system and use the Del key (for ASUS P8Z77) to get into the bios. Go to advanced settings and change the AHCI to RAID. When you select save, your system will reboot and this time, let it boot into Safe Mode.

While in Safe Mode the drivers will be changed. You can check Device Manager if you like and you will see an entry in Storage Controllers for the Intel Deskto/Workstation... . But you need to open msconfig.exe again and uncheck the Safe Boot box. Then close it and reboot back into normal Windows.

If at any time the system tries to do a repair operation, restart and get back into the bios.

You have a few things happening here, 1st your Win7 is probably an OEM (Originaly came w/the system) andassuck is tiedto the original mobo & can'tbe moved.
2nd, you have 1 sys w/ a core2quad processor, and the other has an I5. This means the mobo & memory are different, you have a different setof drivers so thr=e DX4860 will not boot with the older drivers. Normallythis would take aclean install, but being an OEM version - you would need therecovery discsfromthe DX4860.

I have to wait until after the install is finshed in IDE mode, then, apply the reg hacks and copy iastor.sys to the drivers folder, reboot into BIOS setup and enable AHCI mode for AHCI to load.

Ok so have been searching google for a while and came across a few things but still doesnt answer my main question, so i bought a bunch of new hardware including a new mobo and ssd, now the problem im having is trying to decide whether to run IDE or ACHI as there are mixed responses as to whether it will work.

My current setup is 2 intel ssd's and 3 mech hdds with 1 optical drive, so will ahci work?

My board is a Gigabyte 990FXA-UD3 with 6 sata 3 ports, it does have marvell controller but that powers 2 esata so thats out of the question, but basically everything is going to be plugged into the gigabyte sata3 ports will this cause compatibility issues or run just fine?

Am going to fresh install win7 anyway as i need it installed on my new intel ssd but will install under IDE until i can get a definitive answer.

Thanks in advance.

You could try booting with a recovery disc which should get you into an off-line mode where you might be able to use the "diskpart" command. Just be careful:

I finished the XP install and installed Dell drivers for video, wireless & LAN. When I go into BIOS again and re-enable AHCI, Windows does not boot up. I get a few lines that flash on the screen that I can't read and it reboots. If I turn AHCI back to IDE it boots up normally. How can I get AHCI turned back on after having installed XP?

Thanks

You cant if you want to stay with xp. to run windows xp correctly it has to be in the IDE mode. in most cases AHCI is used only for the vista and windows 7 operating systems. if you try to change it back and run xp it will blue screen on you or wont boot at all.unless a computers BIOS only has one setting and theres no other choices listed then and only then can you use the AHCI mode to run xp, vista or windows 7 equally well with no glitches.

A:cant install AHCI Driver in vista

Advanced Host Controller Interface (AHCI) mode is a BIOS option in my computer for the SATA hard disk controller. It lets the OS use Native Command Queuing (NCQ/aka SATA mode) to reorder disk read or write requests to make the reading and writing more efficient, particularly if the disk is very busy.

My BIOS has options IDE, RAID, or AHCI mode. RAID includes all of the ACHI features and Intel recommend that you choose the RAID before you install an OS because changing it afterward can be painful (or "unsupported" if you have an Intel motherboard!).

The process in Vista seems to be less painful than in Windows XP because VISTA includes AHCI drivers by default. However, if AHCI mode was not enabled at the time you installed Vista then the new drivers will not be loaded, and if you change the BIOS setting then Windows doesn't boot.

Simple solution:

Start with IDE mode selected in the BIOS, and boot Windows Vista.
Exit all Windows-based programs.
Click Start, type regedit in the Start Search box, and then press ENTER.
If you receive the User Account Control dialog box, click Continue.
Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
In the right pane, right-click Start in the Name column, and then click Modify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to close Registry Editor.
Reboot, and change to AHCI mode in the BIOS. Windows will detect some changed hardware (anything connected to a SATA port).
For good measure I downloaded and (re)installed the chipset drivers for my motherboard. I have an my motherboard uses an Intel G33 chipset and I wasn't sure if I needed to install the Intel Matrix Storage Manager, but when I tried it told me that I already had a more recent version of the software installed. I guess part of the chipset driver package overlaps with the Storage Manager software

What you are asking in found in the BIOS settings. Read the manual supplied as to how they (manufacture) wants things done.
my MOBO allows (F6) also (F11) and (F12) - (F2) is master access to Bios.

A:cloned C:, installed AHCI drivers, changed BIOS to AHCI, D:'s GPT gone

ok, returning to BIOS and setting back to RAID, as AHCI typeenabled me to view the drive D: again
C: drive seems to be running much more slowly again.
these drives are plugged into the OnChip SATAWith AHCI as SATA typeno drive D:

With RAID as SATA typehave drive D:
but C: definitely dog-tired-slow
I really should not have fiddled with this at 3AM on a Sunday morning!!! Bah, I'm a pro, what could go wrong???

I'm not sure why changing to AHCI causes windows to miss the GPT on the D: drive.
Can I back this GPT up and restore it? Detect it after changing to AHCI? this is my only large drive, I can't back up the entire fricking thing.

The other question this makes me ask is how do I keep my GPT when I move to another motherboard? I don't trust the GPT like I do MBR hm....

edit: changing back again, it does not seem any faster. Doing more reading, it's ok to leave it as RAID because AHCI functions are still available no? So I really shouldn't gain/lose any performance?

I'd like to be able to install just the driver and do it during the installation of Windows rather than after which would just mean upgrading from the default microsoft driver. I can't find the download on Intel's site for just the driver without the whole RST package and I also need information on exactly how to do the install during the Windows installation.

Sorry for my noobness and thanks in advance for any help and information anyone can provide.

A:Verifying AHCI mode After Vista 64 Install

An update to the issue:

After doing a little more research, I found this link:

Error message when you start a Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"

It relates to enabling AHCI after Vista is already installed. No need to go through the process for XP, as is demonstrated here:

HOWTO: enable AHCI mode after installing Windows - PC Perspective Forums (for XP, not Vista)

All one needs do in Vista (and only if enabling AHCI for the system drive) is one registry change.

At any rate, I decided to try plugging a sata drive into the Akasa front port with the system running and, lo and behold, auto-play popped right up and offered its options. I opened an explorer window and could see and manipulate the contents of the drive.

So, if anyone wishes to enable AHCI after a Vista install, it's quite simple. Just do it. But remember, if you enable AHCI for the boot drive, you must edit the registry (as in the 1st link) to tell Vista to load the AHCI driver (Msahci.sys) **before** you enable it in the bios.

I reformatted the HDD on my pre-built Acer Predator G5900 (think that was the model). I had to download the Realtek Lan drivers from the Acer site to get internet access. On the site were two other drivers which I haven't yet installed and am not sure if I need:

AHCI_Intel_9.5.0.1037_W7x64_A
Chipset_Intel_9.1.1.1020_W7x64_A

I've been running Win7 without these drivers for a couple of weeks now, but I do feel that performance is slightly lower than it was before, though I could be imagining it. Are these safe to install like any other driver (gfx drivers for example), and would they have any benefit?

Thanks.

I have a PC that is all SATA, including the DVD drive. I prefer to set the SATA controller for AHCI for the bit of extra performance. However, build 7000 will not install from the DVD drive set like that. So I changed the SATA controller to IDE and was able to install build 7000. I then manually changed the SATA driver to AHCI, rebooted and changed the SATA controller to match. That works, of course. With build 7057, however, I was able to perform the install with the SATA controller set to AHCI. A nice improvement.

I also noticed two other things. The magical 200MB hidden partition is now 100MB, and I think I saw a speed improvement copying HDD to HDD. At one point I saw 130MB/sec copying back files to the C: drive (new 500GB Hitachi) from the V: drive (year-old 750GB Seagate). This PC has an ancient 3.2 GHz P-4 on a new motherboard.

Can someone hit me with a link for manually installing the AHCI driver and switching the OS mode for the storage controller.

If I remember right, this is just putting the driver in /sys/drivers, running a script, and making a registry change. Then you reboot, change the motherboard setting, and then install IMSM after the OS comes back up. I don't remember the script, or if it was just a reg edit, etc.

A:RAID issue - deleting RAID volume to restore non-RAID disks

sadly, there's no way to do what you want without an existing backup.

Look at it this way;
A disk has a container ~ the partition.
The partition as a structure ~ the filesystem (eg NTFS, FAT32, RAID).
We put our data into the structure.

When we create backups, we are getting only the data itself (unless you use an image program like Ghost or Acronis where you get all three).

Deleting the RAID will give back the two independent HDs, but also breaks the structure so that the data becomes in accessible.

-tried plugging it in and going. In POST the controller assigns it as RAID 1+0, (1 drive, RAID 0) but windows doesn't see it at all.

-checked to make sure XP was updated with SP1 for support for large drives. Ok.

-upgraded promise raid controller software.

-The drive isn't showing up in XPs drive utility.

What I haven't done:

-installed on another system using ATA
-installed fresh on this system, changing to ATA in mobo settings.
-Given up on RAID all together.

Has anyone else ever run into this?
 

A:200 gb hd install w/RAID 0

I'm not sure how you run RAID anything on a single drive, the whole premise of RAID is multiple disks.

I have 2 hard drives in Raid 1 configuration. Originally, both were 160 gb. When one failed, I popped in a new 250 and it rebuilt automatically.

Somebody gave me a used 160 gb drive. If I take out the 250 and put in the used 160, my computer sees TWO Raid 1 arrays: one from my own 160, and one from the re-used drive.

Two questions:
-What is the best procedure to wipe the re-used drive and rebuild from my old 160? Can I just delete the unwanted array, and then Intel Matrix Storage Manager will walk me through the correct TO and FROM disks? I've never done this and don't want to wipe my own disk.

-If I instead leave my 250 in the computer, and replace the other 160 with a second 250, will I be able to use all 250 gb? (When you rebuild RAID to a larger drive, like I did, it will only recognize the size of the smallest drive.)

Thanks.

A:How to install old HDD in Raid 1

Rather wipe the "reused" 160gig on another pc (remove the partition as though it was a new drive)
Then put it back in your pc. Your pc should rebuild by itself.

If you use another 250gig hdd and replace the 160 (so you have 2x250gig) then you will only have a 160gig partition. If you first reconfigure the partition of the current drive to a 250 gig partition (by using something like partition magic) and then put in the new 250gig hard drive you should see a full 250gig.

I hope this makes sense.
Basically when you want to change a hard drive in a raid system always swap the drive with a clean one.
If you want to manipulate the partition in any way always do it when one drive is connected and then put the other drive back (but make sure it is clean first).
Lots of programs don't work with Raid systems like partition managers. boot managers and recovery software.

I m having a problem installing Windows XP in a RAID configuration and I think it s a problem with RAID in XP 0 install Can't one of my two hard drives After creating the array with two drives on it I have a choice Can't install XP in RAID 0 of either running my manufacturer s recovery cd or just running windows setup from the CD If I run my manufacturer s Alienware quot factory-setting quot recovery cd the computer freezes up while windows Can't install XP in RAID 0 is starting and if I just run windows setup by itself the computer freezes when there s about minutes left However I can install windows safely and everything if I build the array on the second of the two hard drives alone By doing this I can have a working computer but I have half the space I should and no RAID functionality What should I do I ve tried a few things already but please suggest whatever you think might work I m beginning to feel like it s a hardware physical problem with one of the hard drives What should I try nbsp
