External Sata drive will not keep assigned drive letter

Q: External Sata drive will not keep assigned drive letter

I am running Windows 7 Pro. Have a external dual dock connected to a estata port. One of the drives assigned letter K often comes up as E and I have to change as application is looking for K. Another disk in this dock works fine. No problems.
Does anyone know why this might be happening or anyway to prevent?
Seems like when I go to disk management and assign K it should stay that way.

Preferred Solution: External Sata drive will not keep assigned drive letter

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 (This link will automatically start a download of Reimage that you can save to your computer.)

Try assigning a drive letter a "distance" away from your existing drive letters.

For example, change the dock drive letter to Z and see how you get on with that.

Hi all,

I bought a new SATA Western Digital HD yesterday (WD3200JD/7200R/8M) as an additional HD. I already have a WD 160G drive running as the master. I've attached the new HD to my motherboard (Gigabyte GA-8I915D Pro), but it is not being recognized or being assigned a drive letter. I can see it in the Device Manager, and the report says it's operating properly, but no dice. Belarc shows it as Drive 1 (although the Device Manager lists its location as "0 (0)" - the same as the master), but does not list in local drives.

I've changed the connection position on the motherboard also with no luck.

Any suggestions?

I recently formatted my 1TB Seagate External HDD to FAT32 to backup and redo my PS3. I reformatted it on my Windows 8 laptop easy peasy, but my windows 7 desktop will not recognize it as a drive with a letter to access it. If I uninstall the drive in device manager it will reinstall, be recognized as a general drive and in that small instance it is accessible, but then it gets fully installed and is recognized as BUP Slim BK. It doesn't see any info for the drive or even know that there is a valid partition on it.
Any help to get this drive working again is much appreciated.

A:PC recognizes External HDD. No drive letter assigned.

If THIS is your drive and Seagate software governs it...I'd say that the software for the drive may need to be installed/reinstalled.

My USB disc comes up with the letter 'J'. Because I have references to it with a letter 'X'. I want to change it and I do that in the Computer Management tool with the Disk Management utility.

Computer - Right click - Computer Management
Disk Manegement - Right-click the drive and then click Change Drive Letter and Paths
Assigne a new letter

Everything works fine but suddenly after a reboot Windows 8 loses the letter 'X' for this disc and assignes 'J' again.
I have done so with this drive for years under Windows 7 without any problems. Any idea, please what the problem might be?

Hello Senki, and welcome to Eight Forums.

While you have the USB drive connected, double check using OPTION TWO in the tutorial below to see if "J" is still listed. If so, change it to use "X" instead.

I recently bought a Lacie 1TB external harddrive to store some of the data on my old PC (Win XP, SP2, I cant seem to udate to SP3 because windows update wont work).

The drive is working fine as I've used it on my laptop running Win Vista (64 bit). However, the drive is not being displayed in windows explorer. When I go to My Computer>Manage>Disk Management, I can see the drive there saying it's online, but there's no name attached to it and when I right-click, all the options are grey (otherwise I could of just changed the letter through there).

Using diskpart on command prompt, I still couldn't change the letter. I also found out that there is no volume assigned to this disk.

Can someone please help me?? I'd be forever greatful

A:USB external hard drive recognized but not assigned to a letter/not mounting (Win XP)

I didn't see where you formatted the hard drive. Before you can use any hard drive, external or internal, you have to format it at some point. For hard drives with Windows installed on them, they are usually formatted during Windows setup. For external storage drives, you can format it through Disk Management.

I recently installed a new WD 160Gb drive. I partitioned, formated (NTFS) and installed Windows XP SP3 (using the Windows XP setup program). However, the system has reversed my CD drive and the HD letters.

It gave the HD "E" and the CD drive "C". (It should be the other way around) I can not change the HD letter back to "C". It says I can't change the boot volume letter assignment.

I set the boot sequence in the bios to boot from the CD first, the way it should be for installing a OS, right?

What did I do wrong? Why did it assign my CD drive "C" and my HD to "E"?

In the limited research I have done with the problem posed in post #56, I believe the reason the user is unable to use the drive is it is GPT and is protected. Is there a way to reclaim the drive and data in Windows 7?

I am unfamiliar with GPT and do not know how to get Windows 7 to give access to the drive without changing to MBR, but changing to MBR will wipe the partition table and make the data inaccessible. Any ideas? Anyone else seen this problem before?

the ext. drive anymore. The ext. drive shows up fine on another pc w/ xp

A:Healthy Drive will not allow Drive Letter to be assigned

Hello, and Welcome,
It could be a bad enclosure. When you used Diskpart you used the list disk command, correct?
See if taking ownership of the drive lets you change the letter. The video is for Vista but the same applies to Windows 7.
Other option: Burn a Puppy Linux iso to a CD. Boot Puppy. On the Puppy desktop you will see your hard drives listed. Attach the external drive. You will see a USB icon appear next to the DVD icon. It will most likely be called sdb1. If there is more than one partition on the external they will be labeled sdb1...sdb2  depending on the number of partitions. Click once on the sdb partition. The disk will automatically mount and you should see the files on the hard drive. 
Your Windows 7 partition would probably be sda2. Click once on it and if you do not see your Windows files close out the file manager and try another partition. You can highlight the files/folders on the XP disk using Ctrl+ left clicking or by windowing around the files/folders. Drag the highlighted folders to the Windows 7 file manager window. A small dialog window will appear. Click copy and quiet. You only need to click once on a folder in Puppy to open it.

We typically use "F" as the root drive letter for our network access. One of our new Win 7 (64bit) machines has assigned F to a CD drive that does not exist. The two DVD drives are M & N. When you open My Computer it shows F as a CD ROM drive
but the drive does not show up in the Disk Manager. I've been into the Registry and F is not linked to a DOS device. I"m not sure where to go now.

oh?  try plugging in a card there and see.  maybe then you'll be able to select a different drive letter for it in Disk Management.

Can anyone help solve this problem.

I have two hard drives installed on my PC, and run Win 98 SE. As Windows had been playing up a little I re-installed Win 98 se to try and solve the problems.

Unfortunately Windows now only recognises the C Drive. Both hard drives show in the BIOS, and in System in the control panel. It just doesnít seem to allocate it a drive letter. My CD ROM and CD writer drives still have the same drive letters as before.

I have not changed any hardware, so itís not jumpers/cables etc. The drive has not been re-formatted. I tried doing FDISK from the DOS prompt, and that only showed details of the C drive.

Any ideas ?

Many thanks

When you fire up FDISK and check details, it only shows you the first disk drive, you have to use selection 5 [change disk] to look at other physical drives.

My problem is unlike the ones listed where the drive can't be used. My ACP-EP 512M flash drive worked fine on my W2K pro machine, until the hard disk fried, and and I put in a new disk with Win XP pro. Then the flash drive worked OK for a while (2 weeks?), and now:
- the machine doesn't give it a drive letter when inserted in any USB port (I have 6 or so)
- it shows in the task bar for removing it "Safely remove USB mass storage device"
- Disk management doesn't list it
- it works fine on all other machines, 98 SE, several W2K pro, Mac.

Any ideas?
(It sounds like HW with the computer now with XP Pro, except that it worked fine with 2KPro and XPPro at first, and it works with other USB devices.)

Hi there, I am using a Lenovo Y-50/70 Touch and I recently changed my hardrive from a 1 TB SSHD to a 2 TB SSD. After the migration I faced a strange problem which when I dug deeper I realised that the any drive/partition that I assign the letter D will never show up in This PC as a connected drive to access, although this D drive is visible in Disk Management and appears as a visible drive. However, I can access the drive when I type D: in the address bar of explorer.  I infer, with my extremely basic understanding and knowledge, that my system is for some reason set up to hide drive D, regardless of what it represents, hidden in This PC. I have tried everyting from formatting the D partition, to hiding it and then unhiding. Nothing works. I request the community to please help me solve this problem. CheersAlfi

Windows XP

The letter, F, is already assigned on all workstations to a resource on the server; however, Windows assigns a new USB thumb drive the same letter, which results in an inaccessible USB drive.

I changed the USB drive letter in Disk Management to I. This holds until the USB drive is disconnected and the computer is restarted. Then Windows again assigns the letter, F, to both the network resource and the USB drive.

How do I make Windows hold the settings I give it?

And, why would it assign the same letter to two resources, anyway?

In my experience, when you're connecting a single drive this way, you generally do not have any jumpers set. You could try it that way to see if it makes any difference.

And no, it doesn't matter if any partitions on the drive contain an OS. I do this stuff all the time for the same reasons -- reusing an older drive that has an OS installed on it. I've not had problems assigning drive letters to the partitions on the drives.

I have two hard drives in my computer which is a old Compaq Presario 5WV271 5000 series, both hard drives have Windows XP pro (service pack 3)that I installed on it years ago. It has the max alotted memory, a 10/100 PCI NIC, 900 MHz AMD Athlon Processor, a master hard drive 40 GB (drive C) that I am using to connect here and a slave hard drive 60 GB that says drive D when I am using it but not found when on drive C. For some reason drive C shows a (New Volume F). I am posting here to see if anyone can help me to understand why my slave drive which started out being New Volume F (which it still is when I look for it from drive C) is showing local disk D when I am using the slave. Does anyone have any idea why the slave would reletter itself and how do I correct this?

A:Slave hard drive shows different assigned letter on itself than what is on master

I will try .

Drive letters are normally assigned by the order in which a drive is detected...with one exception. The optical drive is obviously the first drive detected when installing Windows from CD...but it always will receive the D: letter, assuming that there are only two drives (hard drive and an optical drive) attached to the system and, therefore, recognized as existing.

These rules do not apply to any OEM system where a manufacturer has installed Windows and possibly also created either hidden or additional partitions.

Sooo...when I install XP, I have one hard drive connected...with nothing on it...and an optical drive. The optical drive is set up as D: and the partition I create and install XP set up as C:.

I have no card readers or external drives or USB drives attached, since these can interfere with the hardware recognition process.

Once XP is installed, I open it and decide to create additional partitions on my very large hard drive. I create a storage partition of 100GB and Windows assigns the letter E:. I create an additional storage partition of 150GB and Windows assigns the letter F:.

I then decide to install another version of Windows...on the same hard drive. I use my install CD to create the partition and install Windows and it assigns the letter G: to that install...because C:, D:, E:, F: are already accounted for and in use.

I now have a dual-boot, if I have done everything smartly. One version of Windows as the first recognized partition, one version of Windows as the last recognized partition.

All is well and makes sense...until I boot into the other version of Windows. Windows will designate the version which is operative and booted long as it is being used.

So once I boot into the version which had been F:, it becomes C:. The version which had been recognized as C: is now seen as D: from the second version of Windows. All the other drive letters assigned will probably also change...I say probably because a user can make a drive letter assignment "permanent" by giving it a letter such as "W" or some other letter which won't have a conflict with another partition/drive already having that letter.

Bottom line...only one version of Windows can run at a single point in time...that version will always be seen as C: from within that install. It really doesn't matter what letter is assigned any other version of Windows from within that install...Windows only sees it as just another drive/partition.

Until it is booted into...the drive letter is unimportatnt. Once booted into, the drive letter will be C:.

Those drives are gone but I want to install a spare 2TB SATA drive that I have. Using the RAID Management software I have created the drive and it shows the correct configured capacity. I initialized the disk with Disk Management and it lists the disk as online but it doesn't show up in the volume list with a drive letter. My intention is to use the 2TB drive as media storage. Other than combing RAID and Windows 7, what am I doing wrong? Am I better off reformatting everything and reloading Windows?

A:Unable to assign drive letter to newly installed SATA drive.

I had the same problem this week with a drive like that. Have you tried to reformat it? Also make sure your system can handle a 2TB drive.

A:External Hard Drive - Drive Letter changed - unable to change back


Welcome aboard.

Try this:

Download V 0.8.1 from

Drive Tools for Windows

Unzip to a folder. In it you will have two folders Win32 and x64, each containing DriveCleanup.exe for Windows 32bit and 64 bit respectively.

Now unplug all the USB devices from your PC (except of course the Keyboard and mouse), right click on the appropriate DriveCleanup.exe for your system and run it as an administrator.

This will remove all non-present drives from the registry.

Reboot and then plug-in your external drive.

The drive will be installed and hopefully you should be able to assign any free drive letter to it.

Please report whether it resolved your problem.

A:maxtor external hard drive unformatted and undesignated by drive letter

What size is the hard drive?

Do you know what motherboard you have?

STEP 1: CHECK POWER (click for expanded instructions further down the page)

Verify that the drive light and the light on the AC adapter (power supply) is illuminated normally.
It is sometimes necessary to contact Technical Support for troubleshooting and/or possibly to replace the power supply if it behaves unusually.

STEP 2: CHECK CABLING (click for expanded instructions further down the page)

Confirm that your USB/Firewire cable is firmly connected in a port that is on the rear of your desktop computer (if you have a desktop).
Try another USB or Firewire port.
If your drive is powered only by USB, such as the FreeAgent Go, the Maxtor OneTouch mini, and the Seagate Portable drive, then the drive's cable has two USB connectors. Try connecting both of the free USB connectors into a USB port for maximum power availability.
Avoid connecting the drive via a USB hub for now.


Follow these instructions to ensure that your installation of Windows XP/2000 has been updated to the latest Windows Service Pack.

Right-click on My Computer and choose Properties.

The System Properties window will appear. On the General tab (which will be at the front), see the "System:" information.

For Windows 2000: Update to Service Pack 4.

For Windows XP: Update to Service Pack 2.

Allow your computer to complete the installation of the Service Pack.

Reboot the computer and connect the drive. Turn it on and see if the drive is detected now.

STEP 4: CHECK DISK MANAGEMENT (click for expanded instructions further down the page)

Check Disk Management to see if the drive is detected there.

Right-click on My Computer, select Manage, select Disk Management.

Check the upper window to find whether the drive letter is present.

Check the lower window to find whether the drive is detected (such as, Disk 1, Disk 2, etc).

If it is detected as with a drive letter, verify no other device is already using that drive letter. If it is, change the drive letter of the external drive to some unused letter (click here to see more instructions on how to do so).

If changing the drive letter is not possible or the drive does not have a drive letter at all, attempt to reformat the drive (click here to see more instructions on how to do so). This will erase any data on the drive, but since the drive is brand new, there is nothing to erase on it.

If it is still not detected, proceed to Step 4.

STEP 5: CHECK DEVICE MANAGER (click for expanded instructions further down the page)

Verify that your Windows installation contains the most recent Service Pack.

In the left column of Computer Management, click on Device Manager.

Look for the drive?s model number/name in Disk drives (a category under Device Manager).

It will probably not be there. If it is, test the drive on another computer if you can.

If it is not there, check under Other devices (a category under Device Manager).

If under Other devices an Unknown device appears, double-click on it.

Under the General tab, we would expect to see "This device is not working properly" and either (Code 28) or (Code 10).

If Code 10 appears, the drive has most probably failed.
Double-check that you have installed the most up-to-date Windows Service Pack.
Verify by trying the drive with another USB cable or port, or on another computer.
If none of this gets the drive detected, you can begin a replacement order online, or, since the drive is new, you can usually exchange the faulty unit for a replacement at your place of purchase (please contact the place of purchase for a full explanation of their policy regarding returns).

If Code 28 appears, you will need to test the drive on another computer. If the drive works fine on another computer, follow the procedure in this Knowledge... Read more

My External Hard Drive (My Book) was always Drive letter F.

I went to sleep and woke up to find Windows 7 Pro had updated and rebooted and I was welcomed by my login screen.

Consequently now my My Book external HDD now reads as Drive letter G.

I went into Administrative Tools > Computer Management > Disk Management

Drive letter F is not available.

F is assigned to a drive that does not exist and never has. I am confused. I only have one CD drive and it says now that I have 2 even though the one addressed as F doesn't have any information. If I click on F it says "Insert Disk"

A:External Hard Drive (F) Drive Letter changed to G - Can't change back

Update: The mysterious other CD Rom drive seems to be MagicJack.

I did some research but the following tech help did NOT work as you can see by the previous post picture that it doesn't not show it up in Disk Management:

A:Changes to Drive letter & rename causing backup problems to external drive

 I don't use Acronis, but if you think changing the drive letter caused a problem, can't you just change it back?  The Administrative Tools applet of the Control Panel is what I've always used to change drive letters. Changing the name (I assume you mean the drive label) should have no effect.
 Good luck.

I have a wierd problem that most of the suggestions seem not to work.
I have a HP computer with Vista basic installed at factory with no disc sent with computer. I then added an external drive on which I installed Ubuntu OS as the primary boot drive. This was needed while I was learning and using Asterisk. Now I do not need the drive which no longer seems to have a letter designation or Ubuntu OS but cannot seem to be able to use System Recovery. Near as I can tell, I need to reset the Master Boot Record back to Vista only but seem unable to do so as I recieved no disks with the Computer.
Any suggestions. I am not extremely skilled at computer technical stuff so please assume I am an idiot if responding.

I purchased an external USB2 hard drive case (that has a power cable and USB output cable) and installed a 120GB Seagate drive. It seems like my laptop (running XP, USB1) will recognize the drive when I plug it in (as an USB Mass Storage device) but it does not give it a drive letter (like E) for me to access it. I have tried changing the Master, Slave, Cable Select jumper on the drive with no success. When I plug in a USB thumb drive, my laptop assigns a drive letter and I can access it via Windows Explorer with no problems, but with the 120 GB external drive, I have no luck? The drive shows up under the Control Panel.....Device Manager as a hard drive just under my laptop drive, but there is no way to store files on this external drive. Any suggestions?

I am setting up a new computer running Windows 7 Pro 64-bit. I attached an old 500GB USB 2.0 hard drive. System notification showed the driver was successfully installed. However when I looked for the drive in Windows Explorer, it did not show up under Computer.

I ran Microsoft's Computer Management application. Under Disk Management, I see that the drive does not have a drive letter (see attached screenshot). However when I right-click on the drive, the option to assign a drive letter is grayed out. I searched Microsoft's documentation, but the only reason I could find for not being able to assign a drive letter would be if the disk was a system partition or boot partition. But this is just an ordinary HDD that I want to use for backups. What am I doing wrong?

My windows 7 is suddenly applying a drive letter to the system partition, and removing the letter which causes the "new disk inserted" window to keep popping up every half second. In Disk Manager the drive letter appears and disappears every half second.
The only way I've stopped it is to permanently apply a drive letter, which means it is now visible in windows explorer.

A:System reserved partition becoming "visible" and intermittently assigned drive letter by Windows

I assume by 'system partition' you really mean the hidden system restore partition installed by your PC builder? If so, then after I just fired up Paragon Partition Manager to see what it makes of that partition on my Win 7 PC, I find the partition is Primary, NTFS, active, not hidden, volume name WinRe.

The main interesting thing is the volume letter seems to be set to '*'. It appears as (*) rather than (C: ) as the OS drive does. Furthermore, the main menu has a 'partition' tab, where one of the options is 'assign drive letter', and the next option below is 'remove drive letter' which is currently greyed out.

Looking at the standard Windows computer management, storage, disk management, I see a similar picture, except there is no volume letter at all (apparent in that window anyway).

Quite how the partition gets identified in that way is a puzzle, but you might try a free partition manager, such as gparted and see what that says, and possibly allows you to change. As I say above, Paragon Partition Manager might let you de-assign a drive letter but I dont dare try it myself

As part of our 2003 server backup system, we do a copy of data onto a usb external hard drive. The fixed drives are c:\, d:\ for the CD and m:\ for our data. Most of the time, when we attach the external hard drive, it is allocated as the e:\ drive, which is what I would expect.

However, sometimes it is allocated as the f:\ drive, which obviously messes up the backup program.

It occurs to me that if the usb drives are swapped too quickly, Windows still thinks something is on e:\ and allocates f:\ but we tried doing it with a couple of minutes gap and it still allocated f:\.

Is there any way to fix the drive letter or it is always up to Windows to pick the drive letter it feels like?

I have an external USB floppy drive that got assigned the drive letter B when it was plugged into one of the usb ports on the back of my PC.

I need to change it to letter A. The drive is not listed under computer management: disk management. Removing the drive and reinstalling does not chhange the drive letter. Removing the driver in device manager
results in installing new hardware, but with drive letter B. The Bios has several settings releated to usb devices--but nothing to do with drive letters.

so I am at a loss of how to fix this---any help would be most apreciated

Zion880818 - Ditch the external floppy drive on this one. Break down and spend ten bucks on an internal floppy or borrow one from another machine. It takes 5 minutes or less to install and will rid you of your aggravation.

Here are the facts:
I put no floppy drive in my computer when I built it.
I forgot my admin password.
I downloaded a program to recover the password.
The program requires a floppy disk.
I plug my external floppy disk drive in.
The batch program is set to execute on the A: drive.
My external floppy disk drive is the B: drive.
There is nothing in the A: drive.
My USB floppy disk drive will not show up on the disk management scren.

Is there some way I can change the letter of my external floppy drive? I have no cds here, so I can't download that version of the program.

A:Change the letter of external floppy drive?

See if you can disable the floppy device in your bios. Even though you don't have a floppy drive internally, the controller is still there so the bios and operating system reserver A: for the drive letter. You might be able to disable the floppy drive in the bios but I doubt it. See if you can use the subst command I doubt that will work if you are booting from a boot disk though.

I have a situation that isn't really a major problem but is slightly annoying and somewhat Drive Changing External Hard Letter puzzling I have an external TB Iomega USB hard drive on my system It Changing External Hard Drive Letter is set to be Drive Y Most of the time everything is fine But occasionally after I boot the system I'll get the pop up on the screen asking me what I want to do with Drive J And yes the quot new quot Drive J is indeed really my Iomega external drive I can go into Disk Management and reassign the drive letter back to Y and everything is fine again Sometimes it keeps the Y drive letter for several months at a time But other times the system treats it as a new drive and assigns drive letter J to it--in anywhere from a few days to several months after the previous time As I said it doesn't happen often enough to be a problem but I'm curious as to what causes it Anyone have any insights into this little puzzle

A:Changing External Hard Drive Letter

Look in your registry under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. That's where drive letter assignments are stored. Find \DosDevices\Y: on the left side and note the data value on the right. The next time it happens, check the same registry location but find \DosDevices\J: and see if the data value is the same as before. Also see if there's still an entry for \DosDevices\Y:.

I am using 2 IOMEGA model LDHD250-U (250GB) usb connected drives for doing backups.
I connect one at a time, perform backups for a week and then switch the drives.

I was originally doing this with MAXTOR drives. I formatted them with the same drive names and the backup program would not know the difference.

With the 2 IOMEGA's I can't get them to use the same drive letter.

Where can I control/change the drive letter the drive gets assigned when I connect it.

Keep in mind only one of these drive are attached at a time....but I want them to have the same drive letter when they are attached.

Any knowlege of how to control this?

A:Controling the drive letter of an external USB harddrive

Sure. Control Panel, Administrative Tools, Computer Management, Disk Management.

You can set the drive letter there of anything but the boot drive.

Note that assigning the drive letter of an external drive writes a "hash" signature to the MBR of the drive, that's how Windows knows what drive letter it is. If you take it to another system and also assign the drive letter, it'll overwrite the signature and you'll lose the drive letter assignment on the first system.

I turned the computer on today and one of the external hard drives has changed from 'K' to 'L'. Two other external hard drives have not been affected. For some reason the 'K' drive has been allocated to the CD Drive (which was previously 'F').

So how can I get 'K' back to the external hard drive using the same path as before. It doesn't matter what the CD drive is called but getting it back to 'F' would be nice.

One was fine but the other two confused me. I tried to change each one but the letter F was missing. In frustration I deleted that drive. Well, now I can't get it back. What do I do?

First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

You should not have dynamic disks in either machine. What did you do to accomplish this?

I don't have details on what was done to change the drive letter, because I wasn't the one that did this. But here's an overview of the results:

The removable drive shows up in explorer with its new drive letter, however when you click on it, Windows (using Vista and 7) says that it must be formatted before use- checking the drive properties shows a wrong hard drive size.

I'm thinking there are 2 ways of resolving the situation:

1. getting an outside program that will access the drive and allow me to copy the files to a different drive (then formatting the removable drive) or
2.somehow getting Windows to recognize the files on the removable drive.

If anyone knows what software I can use to access and copy the files on the drive or how to get Windows to recognize the drive that it used to recognize normally, I'd appreciate it.

A few days ago, I installed a game on my external hard drive. At the time, the hard drive was assigned the "F:" directory. They other day, I plugged a video camera into my computer before the external hard drive making the camera "F:" and the hard drive "G:".

The game won't work while the hard drive is assigned to "G:". I've removed the camera, there are no other USB devices plugged in (except my mouse which doesn't have any storage capacity) but still when I plug in the hard drive, it goes back to "G:".

I've tried plugging it into different sockets, logging off the computer, restarting the computer, but still, it goes back to "G:".

Hi everyone,

I have a PC running Vista Ultimate x64 and I just installed a 1Tb external hard disk (an eSATA/USB 2.0 combo) Through USB.

The problem is that the OS doesn't assign any drive letter to the external disk.

I tried to reinstall but it doesn't work at all.

In Disk management, choosing to "initialize" the disk, I selected the MBR partitioning style...but it returns an "invalid function" error message.

How can I fix this problem?

The system reads that there is a disk but it doesnt' recognize it and it doesnt assign any drive letter.

A:Vista Ultimate x64 - External hard disk doesn't receive drive letter

Did you format it ? ?

Many drives ship unformatted...

TIP: If you want it to keep the same drive letter even when USB devices are added ( handy for all sorts of reasons ) once it's formatted select a drive letter that's not currently in use and assign give it a Volume name.

This also works with thumb drives as well...

Not if you are using a USB connection.

However according to the standard specification a USB connection point at the computer can supply a maximum of 0.5 Amp which is not enough for many older 2.5" laptop size hard disk, let alone the desktop size 3.5" hard disk.

You need an external power supply or use a twin head USB cable (by hooking to 2 USB port to get 1 Amp current supply).

With XP MCE SP2 using a Western Digital SATA hard drive in a external enclosure, which has both USB and eSATA connections, can the sata connection plug be hot swapped just like USB, or do I need to turn off the external drive first, then disconnect it?

A:e-sata with external hard drive

Everything I've read and heard says its hot-swappable just like USB but if you have the time, its prudent to power down if you're moving the hard drive in the least because you could bump something or jostle it enough to cause some damage in its most vulnerable state. Even the USB drives get the safely remove hardware option that probably should be ahered to but few do I suspect.

A:SATA external drive: partitions?

Not quite that easy. Different OS's have different file system reading abilities and differing file systems, regardless of the file types.

There are programs available for Windows that allows it to read Mac file systems. Probably vice versa as well.

Partitioning is required before any drive can be used by any operating system. Without the "invisible lines' that file systems and partitions create on a drive, there is no way for the operating system to locate the contents of the drive.

You'll need to make some decision. FAT32 is probably the most compatible file system in use, but it is not universal for all OS's.

A:Sata To Usb External Hard Drive Not Working

There's many things that can cause this problem. But the most likely problem is that the hard drive is dead.

Other problems could be:
- the case is broken/defective
- the computer does not recognize the device
- the computer has assigned the wrong drive letter to the hard drive

Does the drive show in Disk Management? If not, then I'd highly suspect that the drive is dead. You'll have to reinstall the drive in a computer and then run a bootable diagnostic to test it.
