Q: Solved: External Hard Drive Letter Has Changed

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.

Thank you.

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.

I have a USB external hard drive that I keep all my documents etc on (had it for years)

I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.

The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.

How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.

If there is no easy way then how do I stop program updates for Adobe etc. failing because they can not find the F drive. I don't know why they look at that drive anyway.


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


Welcome aboard.

Try this:

Download drivecleanup.zip 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.

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"

I have an old BYTECC hard drive enclosure. Trying to use it on an older XP system for back up. Got a bunch of 40G hard drives I can use.

The OS will detect the external drive is connected and powered up, arrow shows in the tray for a USB drive, checked the device manager and it sezs the drive is there and operating properly, recognizes it, but does not assign a drive letter.

AIDA32 sezs it is there but same deal shows no drive letter.

I've tried four different hard drives with the same results. I know the hardware works on other computers, this particular computer USB works with other canned external drives, it reads a flash memory stick as a drive no problem. I know the BYTECC is set up properly, should be the same as with other computers. Works ok on a Win2000 system.

What could be the problem? Is there something to tweak?
I do know this XP system would not read hard drives that had been formatted on non-XP computers before. Don't exactly know what systems all these drives were formatted on. Isn't making any sense to me at the moment. Doing it just like I did on the Win2000 system with other drives, everything worked as it should.

Thinking I could try to slap one of the drives in as a slave and try to format it that way, hopefully can get it to be read as a USB drive instead.

Any help greatly appreciated.


A:Solved: External hard drive not assigned a drive letter

If the drive shows up in Disk Management (Start/Run/diskmgmt.msc/OK), right-click the drive icon or the area showing the drive below, select "Change drive letter and paths". In the next window click "Add". Next window click the radio button for "Assign the following drive letter". Select a drive letter. Click OK.

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.

I have reinstalled my OS several times in the past year due to some problems with my DSL and my external drive has always been been given "F". Now my floppy is "A", hard drive "C", DVD player "D" and DVD recorder "E" and now the external is "G". I know this is correct but why was it "F" before?. Will this cause any problems with the files in it?

A:Solved: External Hard drive changed

It won't cause problems with the files, however it will cause problems with links as they will all be broken. If you have no links to the harddrive then don't worry about it. For example if you have a program that you installed onto the hard-drive instead of the C:\Program Files directory, or you have a JPEG or document on the hard-drive that you open clicking on it's shortcut somewhere else. Links will have to be changed, but that's no biggie

System has two HDs and two disk drives using Win7 Prem.

The main boot drive failed and was replaced. The new drive was assigned as the master and the older drive as the slave. Upon boot, the old D_drive was now the C_drive and the new drive has become the F_drive.

The plan was to install the new hard drive, install Win7 plus backup software, and do a full disk recovery from the disk backup. The recovery disk drive was the failed C_drive.

Through Disk Management, I was able to renamed the current C_drive to D but unable to change the F_drive to C since it is the boot drive.

How can I change the drive letters to what I want and not just rename them?

If this is not possible, how do I get the main boot drive to be renamed to the C_drive?

When I do a recovery of the old C_drive, what drive letter will that be?

Or better yet, how to I get the recovery disk backup to be called the C-drive?

It doesn't matter. That just means something else is taking up the D letter.

If you want to change drive letters:

Go to Start menu>Run

Type in "compmgmt.msc" without quotes.

Under Storage>Disk Management

Right Click on the color strip of the drive and click 'Change Drive Letter and Paths...'

Be sure nothing is taking up the D slot or else D would not be an option.

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.

I have a situation that isn't really a major problem, but is slightly annoying, and somewhat puzzling.

I have an external 1TB Iomega USB hard drive on my system. It 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 "new" 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 have a new 120 gig external USB drive (105G free). It installed and seems to work fine except:
My prior system had hard drives C: and D:
cd reader drive E:
DVD/cd RW drive F:
four-way card reader G:, H:, I:, J: (these came and went depending if card reader was left plugged to the PC)
The new external installed correctly as drive K: and I succesfully backed up a zilllion photos.

After shutting down/startup the drive assignments redefine as
C: and E: Hard drives
D: as new external 105 GIG free
F: as CD reader
H: as a second identical new external 105 GIG free (duplicates drive D
The four way card reader is unplugged-ran out of USP plugs.

1. The duplicate external drive assignment is obviously wrong but I cannot make it go away.
2. I cannot make a backup program work correctly since the drive assignment keeps changing.

How can I "lock in" the hard drive and CD assignments so the external drive doesn't jump in the middle of that alphabet. I want the External drive to always be assigned some higher alpha letter so I can use it on different computers.

My laptop is a Dell Latitude D830 running Windows Vista.

I've bought a Freecom USB 2.0 Hard Drive XS 1TB (Model Code SSYBBA) which came FAT32 preformatted. I wanted to reformat to use NTFS so I plugged it in to my USB port. Opening Windows Explorer, the drive was picked up as G:\ and I could view files on there and copy and remove files so I knew the disk was working OK.

I started reformatting by right-clicking on the drive letter and selecting "Format" from the menu and select NTFS and kept the default settings. After an hour I cancelled the formatting (clicked Cancel) and a message popped up asking me to confirm, so I did.

Since doing this, the drive is now no longer recognised and doesn't get a drive letter assigned. I've tried rebooting, reconnecting and checking in Disk Management and it just doesn't appear (although is powering up when the laptop starts). Also, Device Manager doesn't show it. Screen shot of Disk Management attached.

Can you tell me, how do I get the drive letter back to restart reformatting?

Thanks in advance for your help.

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 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?

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?

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 it....next give it a Volume name.

This also works with thumb drives as well...

How do I prevent this from happening in future when I need to disconnect again?

Thanks for any help you can offer.

A:external hard drive changed designation

Drive letters for external drives are assigned consecutively according to the order in which they are detected by Windows. They won't change until you unplug all of them then re-connect them in a different order - which is evidently what you've done when you removed the hub.

You can't force Windows to assign the same letter to each drive after you've disconnected them. Just avoid doing it or save your iTunes music files on the internal drive instead.

Use the external drive only for backup copies of your music files.

I have an external hard drive that used to be associated with my computers J drive for the longest. One day I turned my EHD off and when I turned it back on it had switched to being the F drive. This is mainly a big problem because all of my Itunes music was backed up to the J drive and now my Itunes can't find my music because the drives switched. How can I switch my EHD from F back to J?

PS. I already tried Googleing the answer and I tried this one:

Using the Windows interface

1. Open Computer Management (Local).
2. In the console tree, click Computer Management (Local), click Storage, and then click Disk Management.
3. Right-click a partition, logical drive, or volume, and then click Change Drive Letter and Paths.
4. Do one of the following:
* To assign a drive letter, click Add, click the drive letter you want to use, and then click OK.

Unfortunately there was no J drive available in the drop down when I tried this. I'm also using Windows Vista and any help will be greatly appreciated.

A:External hard drive changed drives

You are on the right track. You only need to remove the drive letter J from the the drive that it is currently assigned to by clicking remove. Then assign your external the drive letter J. Then go back to drive that you removed it from and assign any letter (F) that is now available.

I made a mistake by changing something I should not.
My system is dutch so I must translate, which is probably not always clear, sorry for that.
Here is what happened:
I opened filebrowser and I saw a little icon with two heads under my external hard drive. I thought that has something to do with sharing. I right clicked on this external hard drive and chose 'sharing with'.
Then on 'advanced sharing' and a new window opened.
I choose the label 'security' and there I saw three user groups to have acces to my hard drive. The first was EVERYBODY (or everyone) which surprised me so I changed it. Now I do not have acces to my harddrive at all and I can not change it back either. It says 'you should have reading permission to see the properties of this object', (or so).
Can anybody guide me through the process to reverse my misstake?
looking for a sollution I found out that I never enabled the possibillity to restore the last systemchange. Well they say one learns from ones mistakes.

Hi Guys!
I need some help. I purchased an external hard drive per TSG help. Thank you. Everything has been working so far. I leave the Seagate External Hard Drive plugged into my USB port, which identified it as being on the E:/ drive. Anything else will be F: drive. Suddenly, the Seagate External Hard Drive is coming up as the F: drive location

I placed some programs, such as the Wise Disk/Registery Cleaner, onto the external hard drive to free up limited space on the C: drive. The shortcut indicates the E: drive so the computer is preventing the Wise Disk Cleaner from running. I have unpluged the external hard drive and shut the computer off several time. Nothing changes the drive's location.

Any suggestions????
Thank you.

A:External Hard drive changed drive location

Hi Siam, you can choose what letter the drive should show up as. To do this, go to:
Start -> Control Panel -> Administrative Tools -> Computer Management and click on Disk Management.
On the right in the bottom pane you will see a list of your drives. Find the external hard drive and right click on it and select Change Drive Letter and Paths... then click on Change and you can select E: from the drop down and click OK.
Hope that solves it...

I have a Western Digital 2TB desk top hard drive which is almost three quarters full. It has worked fine up until yesterday.

Today however it was causing windows explorer to stop responding. I tried to use task manager but explorer did not close until I physically unplugged the hard drive from USB, at which point explorer instantly closed down again. I rebooted the PC and successfully reconnected the hard drive, only for Explorer to stop responding again after just a few minutes of use.

I repeated the above process with the task manager however now I have no access at all to the hard drive, in computer management and my computer it shows as local disk (J) with no meter underneath to indicate how full it is. Computer management shows the file system as RAW, I believe before it was NTFS. Device manager shows the disk does exist with its full name of WD 1021 Elements.

I have tried a few recovery programs, firstly test disk. This however looks like it is going to take potentially a few days to complete. I have also tried the free version of EaseUs. This program found three lost partitions, but none were anywhere near as large as 2TB. Does the paid version find more? I don't want to spend money if it won't work. I have also tried Pandora Recovery but this could not access the drive in question, probably due to problem I am having.

My questions are:

1) Will test disk work if I leave it long enough? And has anyone used it on a 2TB volume and know roughly how long it ... Read more

I have a Toshiba laptop (Pent IV, 512 RAM, 60 GB HD) running XP Home SP2. I recently purchase a Maxtor 200GB HD and an external USB enclosure. After installing the drive in the enclosure and plugging in the USB it looks like it is recognized (says Maxtor drive recognized, driver is installed, new hardware ready to use), but it is not assigned a letter when I click on "my computer" so I can't do anything with it.

After reading an earlier thread, I attempted to format the drive by: clicking on My Computer, clicked "manage", and "disk management". In the main window of this screen only my C: drive is listed. In the drop down list below the main window are listed: disk 0 - C:, and then under that disc 1 - unallocated 189.93GB, then under that my CD/DVD. If I right click on dick 1 I do not get an option to format - only "properties" and "help". In "properties" under the "general" tab it says "Device is working properly".

How can I format this drive and get a drive letter assigned to it?

Thanks for your help!

A:Solved: External HD Not Assigned Drive Letter

Read other 6 answers

I lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?

It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

A:Can't change hard drive letter to needed letter

Hello Stevie,

To be safe, you should create a restore point before doing this in case you make a mistake and need to use it to do a system restore.


1. If the K letter is not being used by another internal drive, then you can open regedit and navigate to:HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
2. In the left pane, Take ownership (step 2 in Option Two of METHOD TWO) of the registry key MountedDevices and "Allow" yourself "Full Control" of it as well.

3. In the right pane of MountedDevices, right click on \DosDevices\K: and click on Delete and OK.

4. Restart the computer to apply. You should now be able to change the second hard drive letter to K.

Hope this helps,

Hey kids:

I'm in a bit of a pickle here. I have my suspicions what the problem is and I hope I'm not right.

Recently my computer died. I pulled my hard drives and DVD drives and stuffed them in another box. I turned it on and it repeatedly restarted after a blue screen of death. The blue screen went by so fast I couldn't read it. Soooo, I reinstalled Windows XP Pro and SP3. After doing so, my second HD is not being assigned a drive letter. Device Manager sees it, Disk Manager sees it and says it's healthy, active and NTFS. Is there anything in the Registry I can change to make it accessible? (ALL of my music and personal documents are on this drive and I can't afford to lose ANY of it.) Or do I have to format it for the OS to recognize it as a drive? Please help soon.

Hello, I have recently carried out a complete reinstall of XP after detecting virus of every kind.

Everthing went ok, but my main drive's letter is now 'I' instead of 'C' , which is now assigned to another drive, if i click on C it states no disk inserted, please insert disk.

How can i re assign 'C' as my main drive, so that my pc recognises it, without difficulty ?


A:Drive letter changed

The reason the drive letter changed is because you have multiple drives on you PC and left them connected during your fresh install. Multiple drives can be more then on internal hard drive, optical drives, media readers, external USB devices. These were still connected and powered on when you did your fresh install.It can be fixed by carefully following these instructions.

Last night I hooked up one of my back up drives via USB. The pc recognized it but it showed a drive letter other than the one I wanted.
Not thinking it through I changed the drive letter. It took awhile to do since I had never done it before.
Now when I plug the drive in, the PnP sees it and I get the tray icon so that I can safely disconnect.
Device manager sees it too.
However, when I hover the mouse icon over 'Computer' in the Start menu, the drive does not show up.
Nor is it visible if I right click on 'Computer' and then click on 'Open'. And Shadow Protect Desktop doesn't see it either, making it impossible for me to make an image for back up.
Since I can't see it when I click 'Open' I can't try to change it back again.
Please tell me how to fix this.

Hi, I'm not sure if the title sounds about right but I have Windows Vista Ultimate with 3 hard disk drives, C, D and E. The D:\ drive is about 55GB and E:\ is 300GB. I'd like to change my E:\ to D:\ and vice versa.

I went to right click on the Computer icon, clicked on "Manage" and went to Storage and then Disk Management...

Here's the screenshot:

I can't seem to rename the D to E as the pagefile is there.. Now, I'm not really an expert on this and if someone could shed some light on how to rename the drive, I'd appreciate it so much!!

Thanks so much in advance!

A:Solved: Help On Renaming Hard Disk Drive Letter

This ones rather easy. Move your page file to the C: drive. (Control Panel, Performance Information and Tools, Advanced Tools, Adjust the appearance and performance of Windows.)

Under Advanced, click on Change.... Click on the C drive and make it System managed size. Click Set. Make sure all the other drives are set to None. After you OK your way out, you may have to reboot.

Now, you can change your drive letters. You can also go back and reset the pagefile. Note, by the way, that changing your drive letters, could cause some programs that look for the drive letters (including anything installed on the drives) to fail.

I have a wierd problem that i don't understand:

Becouse of an unfortunatly accident (whici i don't yet understand), my drive letters change, my C: became D, and so on, and logically, the windows couldn't start becouse it didn't know where windwos was. What was strange, using acronis backup, to restore my windows, it says that C: is actually assignt to System reserved space. I have 2 hard disks, 500 gb each, the first time it crashed, it also made an other hard drive master and the one that should have been master, a slave. I checked in bios, the one that is master is put as a boot devide, first is dvd rom, second the hard disk, the one that is supoosed to be there.
Also, shouldn't the disk with windows on me disk 0?

Those anyone have an idea why is this happening? Never had this problem before and it already happened 2 times in a week, its getting annoying.

Hello and welcome Jack I think you will find that disk 1 is still the OS drive mate if you go to that screen again and right click on that C: partition > open it will show you what is in there ie Windows program files etc see pic of mine. Do the same thing on the other partitions to see what is in them.

OH DEAR!! I should have left well alone.
A while ago, while putting second HD in, my computer decided to assign my main drive to letter F. I recently wondered if I could change this back to C. I found the garb on the net and did so. NOW IT WON'T BOOT!!!! HELP!!! Is there anything I can do????? It starts to boot but gets to a screen that has the windows logo and says Microsoft Windows XP but won't go beyond this. Normally it would bring up the user names from where I would log on. It has been F for a while now and I presume everything will be configured for F NOT C.

I have installed XP onto a spare HD and from there tried to change the drive back to F but it still won't boot. I ran repair from the setup cd and it reads this disc as now being D!!!!


ALL and any help much appreciated.
