External USB hard drive not recognised on Windows after plugging it into a Mac

Q: External USB hard drive not recognised on Windows after plugging it into a Mac


Thanks for any help in advance..

I own a WD MyBook 4TB hard drive, which I've used on Windows for the past 2 years. I got a macbook last week and hooked the drive into it, some error message came up so I figured it wouldn't work, however when I went to plug it back into my windows machine I got the "USB device not recognised" message, the laptop is windows 8. I then tried it on my fathers windows xp computer and it seemed to think it was a completely new hard drive..

I've done some googling on it but I just wanted to ask here incase I went formatting it by mistake or anything..any advice/help would be greatly appreciated.

Preferred Solution: External USB hard drive not recognised on Windows after plugging it into a Mac

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.)

A: External USB hard drive not recognised on Windows after plugging it into a Mac

Sounds like you made some procedural error, allowing the Mac to alter the partition - - bad choice.

Using Windows tools, examine the partition on that drive - - should show up as
somelabel (dl): size HTFS
Healthy (other qualifiers)​
Try Control Panel ->Admin Tools->Computer Mgmt->Disk Mgmt

I noticed that my PC suddenly took a long time to boot up and close down After some testing I found that if my external HD was plugged in that was the cause I thought it might be an indexing delay so didn't worry as all I needed to do was plug External Drive Hard 7 recognised Windows not in the HD in when needed it and make sure I quot Safely quot unplugged it before shutting down But now I can't get access to it at all I hear the usual bleep when I plug it in and it appears in the task bar quot Can I safely remove etc quot but it doesn't appear in Disk Management or Explorer I fear the HD has died although I can detect the normal very slight murmer of the drive when it is switched on I did find the disk using a command prompt but can't remember how I got there Is there any way I can save the data on it I have tried all the usual tests like a different USB port not a hub and a different Windows machine but to no avail

I'm new here, so please don't shout at me if I say something stupid.

Anyway, here's my problem:

I have a Maxtor 500GB stand alone hard drive which I originally bought for a Vista laptop, but have also been using it on my new Win7 laptop.

It has been absolutely fine for the 6 months that I've been on Win7, but today Windows Update decided that I needed 27 (count 'em!) updates to be installed an run - mostly for MS Office.

Anyway, the updates all installed and I restarted upon request, but since then my Maxtor hard drive has not been recognised.

A USB Unknown Device error appears, it doesn't list the drive in My Computer, and only appears in Device Manager as Unknown Device.

Any ideas of how to resolve this would be greatly appreciated, as I have a large number of important documents on that drive which I need to access relatively urgently.

many thanks

Hi there,

I've recently just bought a USB2.0 HDD External Enclosure for a notebook hard drive. I think I installed the drive correctly - the pins fit well and I placed it in the actual case. However, when I plug the USB into my Windows 7 Acer Aspire 5741 laptop, it just makes a funny noise for around thirty seconds and the computer does not bat an eyelid. The laptop just seems to act as a power source and doesn't recognise any drive being inserted. I tried it on a second, Windows Vista laptop and same result.

Is it likely the enclosure/drive is the problem or have I not set it up correctly?

Any help would be appreciated.

I'm wondering if I did something wrong when I disconnected the external hard drive from our new Seagate wireless backup system. I had no idea how to "safely" or "properly" remove it... so I just disconnected the USB cable.

Hi, I am going to clean up my cousin's computer. It is slow as molasses and I am guessing that it is infected bigtime. I wanna plug my external hard drive into the computer so I can backup all the files they want off the computer. I am just wondering if my external hard drive is vulnerable to viruses when I do this? I am going to try to do a Factory Restore. If that doesn't work for some reason I will do a complete reformat. Also it takes forever and I mean forever to get to things on that computer. Is there a faster way to get files onto my external hard drive before I do a Factory Restore? Also if I do a Factory Restore instead of a reformat will all the viruses be gone? Thanks.

I've been using a 1TB iOmega external hard drive with my laptop for about a month and a few days ago it stopped working and isn't being recognised, the power light comes on when i connect the usb cable to the laptop but there is no noise from the hard drive at all and it doesn't show in disk management.

I took it into work with me and connected to my work PC (which runs XP) and it works fine, also tried it on another laptop which is running Vista and it doesn't work.

any ideas? Laptop is an HP Pavilion DV6

A:External Hard Drive Not Being Recognised

The first thing that comes to my mind is, does this external hdd have its own powersupply or does it receive its power from the USB ports only?

If it has its own powersupply, check with iOmega: and see if your hdd requires drivers for Windows 7. In years past, iOmega required drivers for all of its stuff whereas other products you could just plug into the usb and they would work.

If it receives its power from the USB ports, try to use a cable that has two ends for the USB ports, it could be just a lack of power. I have 1 TB (not iomega) that would not work from my front USB ports but will work from the rear USB ports of my desktop.

Let me know how this turns out for ya...

Sorry if this is in the wrong place but I need advice on my IdeaPad 510, it does not recognise my HP external hard drive. I've tried plugging the external drive into all the USB slots, with no luck. The laptop is brand new, only bought three days ago, and my USB storage stick works in it, so I can't work out why it won't find my HP drive. The drive isn't faulty, worked perfectly on my old Toshiba, and lights up when plugged into my Lenovo, but when I go to the 'This PC' section it's nowhere to be seen. I've even looked on HPs website I case I need to download a driver but the HP website says that there isnt any drivers for my external hard drive. Can anybody help me figure this out please? I have a lot of work on that drive, as well as family photos, that I need to access. Thanks in advance

Can anyone shed some light. I have a 40 Gb external USB hard drive attached to my PC. Which was being used exclusively as storage and my PC recognised it no problem. Today I actually installed it into my PC (internal), reformatted it and loaded Windows XP home onto it. As I wanted to save my existing hard disk just in case and install a clean O/S to swap over eventually. I have since taken this disk back out and connected it via USB again and it is not being recognised at all by Win XP. Is it therefore true that if there is an O/S loaded on an external USB hard drive that it cannot be recognised let alone booted to. Any advice is much appreciated....

Hi first post here. My portable hard drive stops showing up all of a sudden. It is connected to a USB hub. When I go to 'Disk Management' in 'Computer Management', the hard drive shows up as Unknown - Not Initialised. Also this hard drive works while not using the USB hub, and the USB hub works as well with other devices. Please help, I need this fixed soon. Thanks!

A:External hard drive not recognised

Powered or unpowered hub? If it unpowered its drawing all its power from the one USB port its plugged into. USB 2 ports are limited to 500 ma max. If you have more than one device on the hub its likely not supplying enough current for the hard drive to function properly. A powered hub can supply 500 ma per port.

I realise there are loads of these kind of threads but none of them are quite the same problem as mine. My Hard Drive has been working fine for a long time but is now not being recognised by computers. The power light goes on, but when plugged into different computers different usbs and with a different usb cable, there is no change to the computer and the hard drive doesnt start movfing and making noise.
I realise its probably broken but is there anysoftware I can get that will find it just so i can recover some data?
Thanks for your help

A:External Hard Drive Not recognised

Try and take it out of the enclosure and hook it direct as a second HD....if it is getting power and it isn't spinning......then if the taking out of enclosure doesn't work..then data recovery company might help but the data would have to be very important as very very expensive.

A:External Hard drive not recognised

Hello Tahnead, and welcome to Vista Forums.

Your friend deleted your hard drive leaving it as unallicated space (unformatted).

If you did not need the data that was on it, then you can just use Disk Management to format and create a new "simple volume" with it. The STEP TWO section in the tutorial below can help show you how to if needed.

Disk Management - Shrink Partition

If you needed to try and recover the data on the drive, then you see if using Paragon Partition Manager Personal edition may be able to undelete the drive's partition for you. Unfortunately, the edition of this program that allows you to undelete a partition is not free and costs $9.95.

Hope this helps,

Is this a small portable drive or one of the larger ones?
Does it have external power for the external enclosure?

I have some bad news for you. if the drive was on when it was knocked over, the heads were in near-contact with the drive platters. That means that the heads probably hit the platter while it was spinning (this is called a head crash). Your drive is probably hosed.

Okay, basically, all the information..I have external casings for my old hard drives from my old laptop. I let my mum borrow one of the old drives, and unfortunately, it would seem as though she has broken it, when it was working perfectly before.

I have it so it's partitioned, one which is FAT formatted, and one which is NTFS formatted. It's total size is 250gb.

When I plug it into my previous laptop it makes a different noise (kind of like an alarm) as opposed to the usual fan type noise it makes. And this is what I get as far as it being recognised;

But it does not show up where it would do usually as a drive (e.g. (F: ))

I have a western digital external hard drive that I use for day to day work.

I recently put it into a laptop PC to copy the contents of a hard drive, it appears that something 'went wrong' in the process and I now cannot access the hard drive.

When I plug it in, I get the standard 'power surge on USB hub' and the light on the front of the hard drive (suggesting that it is still working).

My thought was to re-format the drive, although I am unsure of how to go about this when I cannot access it, or does anyone have any ideas how I could revert the error?

A:Seagate external hard drive not recognised by my computer

I would venture a guess that the simple answer is that the drive was formatted for a Mac and windows is unable to recognize it as such. Now, being said that, with the newer technologies and emulators that Macs and PCs use, I am not 100% sure.

Now for the dumb question, have you tried plugging it back onto the Mac and see if you can read it and copy the file and then format it to the pc so you can use it? that is, if you will need it more on the PC than on the Mac.

I'm looking to upgrade my Windows 7 OS from 32-bit to 64-bit. I have checked that my processor supports a 64-bit OS, which it does.

My question is this:

I have an external drive with about 1.6TB of purchased iTunes data currently plugged into my laptop running Windows 7 Ultimate 32-bit. After I finish upgrading to a 64-bit OS, when I plug this drive back in (or any USB drive for that matter), will it prompt a re-format before letting me use it in Windows 7 Ultimate 64-bit?



A:Plugging in an external drive to Windows 7 Ultimate 64-bit?

Only the operating system is either 32bit or 64. The file system is NTFS and will be just fine when you have 64bit installed.

My 500Gb Sumodisk USB hard disk is not recognised by my 2 Windows machines. Devide manager states the Drivers are not installed.

When i connect the hard disk to another laptop running XP it sees the drive and works perfectly.

The disk manager states XP is using the USBSTOR.SYS and USBSTOR.INF (is this correct or is UBSTOR ?) and can these located in Windows 7 and used as the device drivers ?

A:Sumodisk USB hard drive not recognised Windows 7

The generic Microsoft drivers for all external hard drives are built in to all versions of Windows XP, Windows Vista & Windows 7, therefore your installation of Windows 7 may be faulty with some drivers having been missed out for some reason.

I have plugged in my CORE hard drive, the blue light comes on. I then insert the USB cable into my USB port in my laptop.... nothing. No "windows has detected a new device", no recognition in 'my computer', just nothing at all.

Apparently this is a very common issue, but I still have not found any solutions.

Hi - some advice please.
Trying to recover data from my poorly laptop disc before i reset to factory settings. On my netbook (Win7 Home Premium) i am using some usb connected kit with my 2.5" Seagate disc attached to try to bring it up as an external device to recover my data.
On the netbook, the device is recognised ok in Device Manager but doesn't show up in 'My Computer'. I've tried Disc Management and the disc is shown in the bottom list as Drive 1 and flagged as unallocated - not sure where i go from there. I'm sure i've come across a problem with the ext disc having been Drive C on another system so could clash with the netbook Drive C ?? Any advice greatly appreciated guys.

Bought a new external HDD but my computer won't recognise it The lights are on but no-one's home so to speak I've tried unplugging it and plugging it in again Tried restarting it with drive External not recognised Drive attached Tried it with the supplied -headed-USB lead and with a different lead in several different USB ports - back front hub powered hub The best result I got was that once the computer tried to load the drivers for the device and then said the device was not recognised and got the quot try again or replace the device quot message It doesn't show up at all in the device manager so I can't even update the drivers to make it work This computer has done this before with a couple of other External Drive not recognised devices -most recently with a hard drive that used to work on this machine until the power supply for External Drive not recognised it burnt out but then I had to do a fresh reload of Windows and suddenly the HDD won't show up even with a new power supply Usually it's a case of finding drivers or firmware or windows updates that fixes it but since I bought this from ebay without packaging and don't even know what model the HDD is I'm going to have trouble finding the right program for this one The HDD did work for a few minutes on my Windows laptop so the HDD should be functioning though it then decided to reject it from that computer too so maybe driver issues there as well Any ideas

A:External Drive not recognised

So, you bought a "new" HDD without packaging and have no idea what brand and model number it is? There's no markings anywhere to signify the model number? Any reputable hard drive maker will indicate this very pertinent information somewhere, in addition to all the stampings of approval from various authorities (UL, CE, FCC, etc). Either the seller stripped off the placard or put the drive in a generic casing, both of which raise the suspicion meter into the uneasy zone. FWIW, I recommend you stick to brand new sealed package HDD's in the future. It brings a peace of mind as well as the recourse to return it or get warranty service. With this particular HDD, you may not even have the chance to return it to the eBay seller if it is established that it is faulty.

If your Vista installed computer has a history of not recognizing other devices, this compounds the problem. But, you say that the HDD worked only for a few minutes in W7 before it ended up "rejected" or not recognized. Maybe you have a bad USB cable. Try swapping that out and getting the HDD to work on your W7 machine before anything else. You want to establish that it's a functioning device before dealing with the problem child Vista computer.

Finally, be sure you've applied SP2 (service pack 2) to Vista and run Windows Update to get all of the latest updates. Earlier versions of Vista had device driver issues that were rectified in SP2 and later.

I have a MECER external drive which suddenly is not recognised by one computer, but is recognised by the other. Both computers have legit XP Professional operating systems which are up to date. I have no problem with my other VANTEC external USB drives.

The MERCER used to work then would not, so I took it to MERCER agent who "repaired" it. Then it worked for a while then stoped again. Took it back to agent who tested it & said there is nothing wrong. Brought it back and it worked - for a while, now its gone again. All along it has always worked on my older 2ND computer.

I have tried different USB ports, changed USB cables, reformated the drive on my 2ND computer - still no luck. I get the message:

"One of the USB devices attached to this computer has malfunctioned, and windows does not recognise it"

A:External USB Drive not recognised

No Response? I have done a search on this forum and read through 500 similar threads to mine and still have no answer.

since my drive works on my 2nd computer the drive and the inclosure must be OK? Since both computers have XP Professional does that mean it cant be a problem with the operating system?

So that leaves the computer hardware. Is there a conflict between the inclosure and the motherboard???

Why is the problem not always there??????

Earlier I also recieved an error message when shutting the pc off, I don't know exactly what it said. Something about Memory...

I did a system restore on the Vista Ultimate PC to the earliest possible date since I could not be certain other updates etc were having an effect. I created a new folder under C:\ and named it C:\ usb drivers as detailed elsewhere within the driver forum and copied all INF contents into C:\usb drivers.

After boot up I turned the external drive on and to my amazement it was now identified as a Samsung compared to previous Classic SL description. It looked for the driver and was installed, job done.

How do I get the windows setup to see the hard drive and proceed with setup?


A:Solved: Install Windows with External Dvd Drive - Hard drive not found?

It is usually because the installation cannot recognise the SATA driver for the hard disc
If you have a usb drive load from Toshiba the sata controller drivers
so on the screen for the install you press F6 load drivers and then load the sata driver from the usb - I say usb as I presume you do not have a floppy drive
OR you can include them in a reburnt CD using nLite but that is a longer way round the problem

OR you can TRY try this

Enter your BIOS/Setup Utility
Locate the Serial ATA or SATA configuration section
I’ve seen this section called ‘On Chip Config’ on some Phoenix Award BIOS

On Lenovo/IBM ThinkPads it’s in Config > Serial ATA (Sata)
Change the mode of the SATA controller from AHCI to IDE or Compatibility
Save & Exit
Reboot and begin the Windows Setup again.
If Windows Setup successfully detects your hard disk this time then go ahead and perform the Windows Setup.
When Windows setup completes change the mode back to AHCI in the BIOS

normally when i turn on the external hard drive it autoplays but it doesn't do that anymore.

i don't understand why it shows up in my devices and printers but not as a drive when i open windows explorer.

i've looked into the external hard drives properties and it all says that the device is working properly.

Go into Control Panel (classic view) ---> Administrative Tools ---> Computer Management ---> Disk Management.

In bottom-right pane, if you see a horizontal band representing a drive with no drive-letter assigned to it, that's the cause of your problem. You need to give it a drive-letter:

Right-click that horizontal band and choose "Change drive letter and paths".

Hi guys, Ive seen variants of this question during my searching but have been unable to find an exact solution.
I have Windows XP running from an 80gb SATA drive into my msi 865pe neo3 mobo. I have been trying for the last few hours to get an 80gb ide hard drive (Seagate Barracuda 7200.7) to register with windows to no avail. My BIOS sees it plain as day but when I get to windows it simply doesn't exist. I have tried various BIOS settings and all jumper configurations. It won't appear on the Disk Management Utility for formatting either.

Any suggestions would be incredibly welcome!

XP, SP1.
I installed a second HD, (IDE), as extra space for files. It is set up correctly as a slave to the main HD and appears in BIOS and on-screen at start-up. Acronis also sees it. However it appears nowhere in Windows, not Device Manager, not Disk Management, not Add hardware, you name it, it's not there.

I formatted it with Acronis as logical, assuming the computer sees the two drives as one. That's one possible clanger. Can you suggest anything else? This ought be so simple.

By the by, I looked at the Hitachi site and mine doesn't appear on their list of HDs - I've asked them how to find it. There was no driver with the HD and they say drivers are no longer needed for XP.

How did you format a drive that the OS can't see?
You may have better luck with Cable Select.
What's the computer specs (Make, Model, Mobo, etc.)?

Hi, i just purchased a new seagate SATA2 500 gig hard drive, with the intention of cloning my primary disk due to: 'pri master hard disk smart status bad'

I currently have 3 IDE drives and when i connect up the new drive it is not recognised, and showing up as a CD-Rom drive

Does anyone know how i can fix this or of any common problems between IDE and SATA2

any help will be greatly appreciated


A:new hard drive not recognised

Check in Disk Management of the Administrative Tools -> Computer Management in the control panel. See if you see your drive in there. Brand new drives don't have a partition set up on them yet, so Windows can't read/write to them, you'll have to create a partition first, which can be done in disk management.

Are you sure its showing up as a cd drive? I've never heard of that.

ive been hleping a friend out a couple of days now with his pc cos it screwed up.
the day his comp screwed he rang the company for his pc, the told him to go on the setup and the HD was not recognised, so they told him to do something to delete somethin go the HD but couldn't, so the person on the phone told him to put the restore disk in and redo windows and that worked fine.

So today i installed the broadband modem for him and the PC worked fine. Then i downloaded and installed Norton Anti-virus and internet security wich worked fine. Then i updated it and restarted it like it said, Then it just wouldn't load up, i looked on the setup screen and the HD wasn't recognised.

Any ideas why its not working ?

Thx for the help

I purchased a 20 gig Fujitsu h drive in a sale, hooked it up to my old p2 computer, it does recognise it at start up but not in win explorer. It is probably wiped clean, but it is spinning. I have tried setting all drives to auto in set up, different jummper configs on drives, but nothing happens. I have tried a known good drive but still it wont see it. If the computer wont see it how can I format it. I have a feeling the drive is ok and something else is wrong> Interested to hear you views on this one. regards Dotry

A:hard drive not recognised

I assume you are adding it as a 2nd Hard Drive to a computer. Make sure its hooked to the secondary IDE Cable connector, and the cable connector is inserted well enough into the back of the hard drive. Make the 2nd hard drive a slave, you can do that by changing the jumper on the back of that HD.

When all this is done, boot up your comp with a boot disk, run the FDISK command and create a new partition so you can begin using the hard drive

Am hoping someone can offer a simple solution here!

I have just had to reformat both my hard drives and reinstall windows on the primary/master drive. I have a program from Maxtor to wipe the second drive, which I ran overnight last night.

The computer boots up fine, and a little message came up in the corner of the desktop saying 'new hardware found, hard drive' but its not showing up in my computer.

I have checked the cables and the switches, all are in the right place, am not sure what else it can be - all help appreciated!

A:New hard drive not recognised as C:

I have had the same probs in the past with Win XP and usually have to resort to disconnecting the old drive, loading XP on the new drive....which is now the c: drive.....and then reconnect the old drive which will now be your F; drive. Its not a very glamorous fix I know, but it works.
I have a zip drive on my machine which it sometimes calls the c: drive if I need to reload XP and my hard drive as the F: drive. Yet if I redo the installation, the second time it will correctly call my hard drive the C: drive......go figure...cos I can't.
Someone on here may have a better fix.

Do this instead

Open the working computer up (side cover off, and power off too!)
Unplug the CD/DVD Drive data cable
Plug the faulty HardDrive into the data cable, and also plug in one of the molex power cables (you can use the CD/DVD Drive's power cable too)

Make sure the HardDrive won't hit anything and short it
Turn on
Once Windows finds the new Drive, then check My Computer

Dell Inspiron 14 3000 Series
I have this laptop. My question is why would you sell a computer with 32GB hard drive when you know the OS will take up 20GB? How am I supposed to use this computer? I can't upgrade the HD and why should I buy an external drive for a laptop?
I am so utterly confused.

A:Can't use laptop because Windows 10 is using 90% of the hard drive, what can I do besides using an external drive?

This isn't a true notebook - it's a glorified tablet/internet appliance.  It's fine as a Windows substitute for a chromebook, but forget running anything demanding on it -- it's designed for a single purpose:  to be inexpensive.

The problem is that whenever my power management settings spool down my 2 internal hard drives, (or of course, the system enters standby or hibernation), my secondary hard drive is not recognised again when I come back to my pc. I have to restart.
This has always been the case and something that I have always got around my simply not using these power saving features. Its about time that I think about my unnecessary power use and try and sort this out!
Im running XP SP3 on a custom built fairly old Athlon 64 system. The drives are both SATA1 and are 120GB for the system drive and 350GB for the secondary.

Anyone any ideas how I can either prevent this or simply restart the drive without having to reboot the pc?

try auto detecting the hard drive then saving your settings in the bios menu.

thanks for any help in advance,

You cant really do anything in BIOS other than ensuring SATA/RAID are enabled . Windows needs to load the drivers . During XP Setup loading files I presume you are hitting F6 when prompted ?

I have 2 hard drives in my pc. Drive C has the operating system install on it and Drive D has my personal files on it. I disconnected Drive D as I think it's about to die but when I disconnect it and then turn the pc back on, Drive C is not being recognised.
I checked the bios settings and it wasn't coming up in that either. So now I have reconnected D drive and it's recognising them again.
How can I disconnect D drive without it affecting C drive with the OP installed on it?
