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.

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.

Hi all, hope this is in the right place.

I have a laptop with Windows installed on a 128 GB SSD (labelled C) and a currently empty 1 TB HDD (labelled D).
Essentially I would like to swap the labels around, so the SSD with the OS is the D drive, and the HDD is the C drive.
The HDD needs to be labelled as C for work purposes - we share a lot of linked files so need consistency there.
I have two questions:

How do I rename the C drive? Using the "Disk Management" tool I can freely rename the HDD, but because the C drive is in use I am unable to make changes. The exact error given is "The parameter is incorrect".Will renaming the C drive to D cause problems with the OS booting? (I'm relatively OK with other programs having issues as that can be fixed, and I've installed very few at present)
If you have any other solutions that don't involve renaming the drives that would also be much appreciated.

Thanks in advance!

A:Renaming C Drive Letter

Back in XP days you could install the OS on a partition other than C:. But with Vista and later the OS has to be C:

Is the HD a USB external? The only way I could see to do it without taking the SSD out would be to restore an image of the OS onto the external and boot it as C: then install the work programs. To run the programs you would first have to boot the Laptop from USB instead of the SSD.

Also I am not sure if you can do that without any licensing problems. It may be easier to pick up a used W7 machine with a large HD and just install your programs on it.

Hey TSF, i'm a student, and I recently bought a 500gb External Hard Drive for use with school. I also bought a PS3 and would like to add my music and movies to that. I researched about the PS3, and learnt I needed to convert the hard drive type (not sure how to describe it) to FAT32. I decided to create a partition, so the whole thing wouldnt be converted to FAT32. But after something I did (I've used Swissknife, but it didnt work, maybe thats something to do with it), one of my partitions that was previsously unallocated space turned into a primary partition. However, it wasnt labelled as healthy or as a primary partition (im just presuming it is because of the blue on the Disk Management window), and also with no drive label.


A:[SOLVED] Partition has no drive letter.

Sorry, here is a screenshot.

Im not bothered if I have to format it, as I dont have any data to lose on the HDD :)

Well I have this problem..
My XP OS wasn't starting so I had to reinstall it in order to fix it..
Well that is where the problem start..
I had Dualboot, with Vista and XP.. Now, I fixed the boot so now I can choose wich one start but when I start XP the XP Partition Letter doesn't change to C: , Its stays in E: and before the reinstall it used to change to C: ..
I tried to do again the boot stuff with Easy BCD and I did, I deleted the XP entry and did it all over again but when I booted on XP the letter wasnt changing..
Now I cant install anything because XP doesn't seem to know thats its installed on E: so its try to search stuff on C, where now is Vista Partition..
I hope you guys can help me.. If not I would have to format XP partition.. I have no problems with it but I just want to make it like the last choice..

I have a dual Raid 1 configuration with (2) identical 500GB (C and 1TB (D drives. When connecting my (2) external hard drives, one of which needs to be named (F (I have numerous files, folders, icons and programs linked to it), I see that (E and (F are the only two drive letters unavailable for use - presumably because they have been allocated as the invisible/dynamic? drives for (C and (D, respectively. How do I know which one's RAID Mirror is? And can I just rename that drive so the letter becomes available without interrupting/changing/affecting the RAID configuration?

A:[SOLVED] Change drive letter on system partition

Remove all drives except the System Drive (previous D:) which is on the Primary Master controller with the jumper pins set to Master, and restart the computer. The System drive will now be C: Now shut down the computer and add the 20 Gb drive on either the Secondary Master controller with the jumper pin set to Master or with the jumper set to Slave as a Slave Drive on the primary chain, on restart it should be the D: drive.

I am trying to help a friend.

I built a desktop computer for him, Dec 2011.
W7 Home Premium SP1
HDD haD a single partition, C:, onto which I installed W7, using a legitimate, commercial W7 DVD.
W7 was activated. Updates were downloaded & installed using W7's automatic update feature.


The HDD is seen by the BIOS; within the BIOS and from the boot menu.

16 Aug 2012, the computer worked properly; shut down normally.

The next time he turned the PC on, 19 Aug 2012, the boot process proceeded through the Windows 7 splash screen.

NO login screen appeared.

Spontaneous reboot.

W7's automatic repair screen appeared, advising that W7 could not be repaired.

Things I have tried:
System Restore point; tried twice.
1 restore point, for 15 Aug, notes Windows Update.

System Restore advised that it looked at the D: drive for restore points. None found.

A:[SOLVED] W7 system partition drive letter changed won't boot

Hi, boot to the RE (repair your computer) at the x:\sources prompt type:-

bcdedit (press enter) this will reveal the boot manager and the boot loader that your OS uses to boot. Note down the entries, next type:-

bcdedit | find "osdevice" (press enter) this tells us what drive letter the RE has assigned the OS, not always C:

It will be this drive letter that you will need to use to repair the boot .

Have just installed a new 8.7 Maxtor in a P100. This drive is set as master and partitioned into 5 which assigns drive letters c,d,e,f,g . If I re-install the old 500mb drive unit as a slave ( Quantum Maverick) it assigns itself as drive letter D. I want this drive to show up as drive H . If I go to Device manager, hard drives, double click on generic ide type 47, settings, for this drive the drive letter assignment is there, but I cannot change it. Any ideas please.

A:{SOLVED} Slave drive letter inserts itself within master partition drive letters

I don't think you can change it. Normally the bios will take the primary of the 1st ide drive as c, the primary of the second ide as d, the next partition of the primary ide drive as e, etc.

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,

I have a drive that has a lot of information on it that I need. A user left our company and all of his files are on this drive. I was handed it and asked to build a VM with all his information on it. When I plug the drive in it loads the drivers and shows
up just fine in Computer Management (shown below), but not in Computer. So I think, ok, I'll just add a drive letter but that option is greyed out and won't let me. The disk is initialized and appears to be healthy. I have gone to device manager and made sure
there were no problems there as well. It was also an external drive so I removed it and made it an internal drive on my machine but got the same results. It shows up in BIOS but obviously can't boot off of it since it is not an OS drive.
Deleting/formatting the drive is not an option. Is there a way to get this drive accessible without that? Deleting it is the exact opposite of what I want done here.

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?

My sister did something to her computer and reinstalled Windows XP. The thing is that it is installed on a partition (labeled "e") with only 3 gigs. I noticed this because I tried installing more software and it said that there wasn't enough space on the hard drive.

I searched online and found that I could see both partitions using the disk management utility. When I use this utility, I can see the partition labeled "e" and the other larger partition (75 gigs) and it doesn't have a drive letter. I have tried adding a letter to it by right-clicking, and all that it shows in the menu is "delete" and "help". Both partitions are labeled as "healthy".

How do I get back to that partition? Are all the programs, drivers, files, etc. still on that partition? How can I get the computer to start up on that partition? Windows XP is now installed on the smaller partition - should it be removed eventually?


A:Partition without a drive letter

The little partition was most likely the "System Recovery" partition that came with the already installed software setup when she bought the PC.

Somehow she has clobbered (a techie term ) the main partition that contained her data and Windows installation.

If she has a set of System Restore Disks (CD's), then she may be able to use them to restore the HD to its original state...like the day she bought the PC.

If not, and it were my PC, I would use FDISK to remove everything from the HD, and then recreate a single partition of maximum size on the drive. Next Format it, and then reinstall Windows...going on from there.

I have Windows 7 RC on my Computer. It is on Drive C:

A:Change Drive letter: Partition containing OS

I have never been able to change an OS to another letter without bricking the OS. The only tutorials for doing so make it clear it is only if the OS letter has slipped.

What I would do is save externally a backup image of Win7 using an imaging software that will allow you to select where to reimage, such as Paragon Backup & Recovery Free Edition - Free Download or Macrium Reflect.

Then go ahead and do the Vista factory restore, shrink Vista partition in Disk Management, reimage Win7 to the shrunken space. Now boot the Win7 DVD Repair console to run Startup Repair up to 3 separate times to rewrite the MBR to Win7 and possibly configure the dual boot. If not, use EasyBCD 2.0 beta in Win7 to add VIsta.

Others may have an easier idea. You'll have the backup image as a path back, so it's worth a try since Win7's drive letter is in most cases relative anyway.

Hello....great forum!
my C: is a SSD Id like to have back as one disc, one partition..

The 101 mb 'unallocated' It was previously listed as " reserved system protected drive" I removed and formatted its 101 mb...back to empty, unallocated, can I lose that partition??

It shows up under disc management as a part of c...but really has no drive letter at all it just shows as C:

Many thx for ideas rick

A:SSD partition on c: sys drive. has no letter 'unallocated'

Are you currently using that C as your OS partition, if so, you need that other partition as is..

101mb is roughly the equivalent of 60 photos, your temp internet files can be 10x that amount. and its not not taking up a drive letter.

I have a triple boot desktop computer with XP, Vista, and windows 7, and some storage partitions as fat 32 and ntfs types. Each operating system shows the partitions with different drive letters. From booted in the XP it is drive G, Vista is C, 7 is D, and with the 2 optical DVD/CD drives, and the 3 storage partitions, I can change those drive letters some to allow drive E to then become available for the XP system. So is there any way to change my XP from drive G to E, such as booting to the XP recovery console and using the diskpart or map commands, or some registry edit to do this change, thanks.

However when I attempt to change the drive letter using Windows Disk Management, "R" is not shown as a choice.

I don't understand how, but when I installed XP MCE, it was with all other drives disconnected. However, when I went to Disk Management, it's partition is labeled G:, while W7 is labeled L: when running MCE. I want to change G: to the usual C:. but Disk Management won't permit that, and when I tried something similar with Acronis Disk Director some time back, the OS would no longer boot, so I'm not anxious for a repeat performance.

The question is, how to relabel the partition safely?

A:Changing OS Partition Drive Letter

I wouldn't and don't think you can change it, not without re-installing. As you have seen Windows won't let you change the drive letter of the partition windows is installed too. The main reason is that doing that would break a lot of programs etc. They would be looking for the old drive letter not the new one. Do you have a flash card reader installed? If yes that would be my guess as to why the drive letter got to be so high. I've seen that happen in XP if the hard drive wasn't formatted. It doesn't get a drive letter until after its formated. The other formatted drives would get C:, D:, etc. I didn't think windows 7 did that anymore but I could be wrong. Like a lot of people, I've only been using it for a short while. Now that the drive is formated it should get the first drive letter C: so a re-install should fix it. It just depends on how much that bothers you as to whether you want to do it over again.

Run into an issue with a hard drive showing 3 partitions, but I can't assign a drive letter to it.

Background: It was running Win 7 Pro 64-bit, but was having occasional issues with blue screening. I've pulled the hard drive from that PC and have it hooked to my own (also Win 7 Pro 64) via USB external HD enclosure to run scan disks.

A:Unable to assign drive letter to HD partition?

Hi FuryoftheStars,

First let me tell you how to make a full screen Windows Disk Management screenshot.

Before you take the screenshot, go to the top menu bar and click on the "Show/Hide Console Tree" and "Show/Hide Action Pane" to hide those. Then we can clearly see all the columns in the top listing of the drives. Sometimes that information is necessary.

A sample screenshot with no information obscured/truncated:

Now a straight answer to your query:

The OEM Recovery partition in this case (and in most other cases too) is deliberately of a different Partition Type so that users cannot access it with Windows, meddle with it and spoil the broth. You may change the partition type to the normal type accessible to Windows and then assign a drive letter.( If you want to do it, do it at your own risk .)

If information on it is already available, I do not want to rewrite it . Please see Techno Wizard's last post dated 21 Oct 2013 here Assigning a letter to OEM Partition ( Take only what he says about recovery partition. The hibernation partition is not applicable here.)

(Now on my part ) You can also change the partition type using MiniTools Partition Wizard.( Changing it with diskpart by normal users is a little bit tedious and requires care)

EDIT: You can ascertain the current partition type from the "Properties" page in the first right click menu ( the last in that menu)

Then it continued normally until it said 'Preparing your desktop'. Then it came with blank blue-ish screen and in the bottom right conner said "This copy of windows is not genuine" which it is. Signed me in to a temp account couldn't access any files. Turns out it was trying to access D:\ instead of I:\ no programs worked.

Ok i know this sounds stupid (hey, it's windows) but how do I end up with 7 primary partitions? I thought you could only have 4. Anyway, one of my partitions no longer has a drive letter so I can't access anything on it. I'm unable to right click it in disk Management to add one, the option is grayed out (see pic).

1st partition = 100MB win7 boot
2nd partition = the windows OS on it's own 50G partition
3rd partition = 50G FreeBSD Unix (this is a multi-boot system)
4th partition = 500G data partition, the one that lost it's drive letter D:.
5th, 6th, and 7th partitions are Linux partitions and the last one looks like an extended partition by the green outline.

I've used this system successfully since last year when win7 came out. It's worked pretty good but all of a sudden it lost the drive letter for the 500G data partition. I have no idea what happened or how to get it back. Any ideas?

A:Can't add drive letter to partition, have 7 primary partitions

Shot in the dark:

As you said, you can only have 4 Primary Partitions. I suspect that Windows knows this and is therefore saying "Well that can't be right" and assuming its made a mistake and won't let you assign drive letters.

If you get it down to 4 partitions again, it will probably let you assign letters.

Recently, i attempted to set up xp in even another paritition. That's a whole other story. I ran into trouble, gave up, ended with a fouled up boot manager and decided to reinstall windows 7 from the install cd.

Before reinstalling windows, I made a partition on a second, exterior hard drive and backed up my documents partition in it.


With Windows reinstalled and with the exterior hd connected, the partition with the documents does not show up in My Computer. It does, however, show up in Disk Management. But it has no drive letter. And if you open the right click menu on that partition, everything is greyed out except "delete partition" and "help."

Maybe I neglected to assign a drive letter on the back up partition? But wouldn't the system do that automatically? Maybe the drive letter assigned by the system conflicts with a drive letter on the inside hd?

How do I rescue my backed up documents?

I am hoping someone here will know what I should do.

I installed an old partition I imaged ready to put on a new hard-drive. I need to make it so the system does not see it as drive letter "C" as that is not what it was originally (particularly when the programs on it were installed). I boots up fine most of the way but then when it gets to "Preparing your Desktop" it hangs for a long while and when it comes out of that, it dispays "This version of Windows is not genuine"

I should sat at this point, My copy of Windows is genuine.

Is there a way I can change the drive letter of this partition back to the value the installations on it expect as at the moment it thinks it is "C:" which I believe is what is causing the problem

The old partition I am installing did not have the drive letter "C", it had "O". I know this was a bad mistake to make but it is too late to change now. This is the partition I used that has the most programs installed which are useful for my uni coursework. I can start afresh but would rather not spend all that time at the pc basically waiting for each installation process to run.

I have a multiboot system with Win XP thru Win10 over 2 separate(non-raid) SDD's. I mostly live in Win 7, But Win10 is looking really good now.
On the drive with Win7, I have that Reserved System partition. Somehow over time it received a drive letter D:.
Will it cause any trouble if I remove just the drive letter from this partition? I do NOT want to delete it. Just want to free up some space in Windows Explorer. I can't use that little partition for anything so why see it everyday? I'm not sure on which partition my MBR/bootloader in located. If it is in this little partition, and I remove the letter, will I have problems booting on the next re-boot?
I use EasyBCD as my bootloader program. I have a copy loaded in each OS.
Thoughts/ Suggestions?

Next somewhat related question. In each Win install the drive letters get mixed up. for example I have a large Data HDD with no OS on it. In Win 7 it has drive letter M:, in Vista it is L:, in Win 8.1 it is S:
While working in each OS can I change the DATA HDD drive letter, and not have a problem in another OS?

Thanks everyone!

I see this has not been updated for a long time.  I just bought an HP laptop, and I have the same problem.  But the laptop has Win 10 Homne installed so, as I understand it, I don't need the 15 gb of OEM Recovery as d:, do I?

Hi, Well, that is your last resource to perform a Recovery when your machine goes bad. You can make recovery media (DVD's or USB) and keep in a safe place. After that you can delete D: (even not recommended). Regards.

I hope to find help in this forum.
(I just tried another, German Win7 forum but until now they don't have an idea ...).

I'm using an external USB HDD (Toshiba Stor.E Basics, 500GB) which is divided
into two partitions (with "MiniTool Partition Wizard 9").

I've no problems with all my (old) XP prof. systems.

Conecting the HDD to my Win7 prof notebook (Lenovo W500) as well as
to my Win10 home tablet, only the first partition will be recognised.

Here you see the screenshot.
Using MiniTool Partition Wizard (on the Win7 system), the 2nd partion will be found - but without drive letter.
Trying to assign a drive letter with the Minitool results in a positive message, but then, the same state again is displayed: no drive letter. (Assigning a drive letter with Win7 routine is impossible.)

Here, only just mentioning it, the screenshot of the drives and partitions on the XP system:
Any idea?

Thanks in advance!

A:Win7 (+ W10) 2nd partition of USB disc not recognized, no drive letter

Hi digait and welcome to sevenforums.
On your external HDD simply right click on unused partition and select "create new simple volume". That should allocate the space as active and assign a new drive letter. See tutorial here.

having to configure a new HP laptop with pre-installed Win7, I need to create some extra logical drives to organize things better.

Unfortunately, the usual OEM scenario applies: all four possible primary partitions are already happily taken by the manufacturer:
SYSTEM (no drive letter),
Recovery (D:),
HP_TOOLS (no drive letter).
(Why can't they just make one partition Extended to begin with...)

However, this thread and similar ones here contain excellent info*, so I know already what can be done. I don't want to touch SYSTEM, and don't want to remove Recovery or HP_TOOLS; so the only option for me seems to be to turn (C:) into an extended partition, then shrink, then add logical volumes as required.
Sounds feasible enough**.

The one remaining question I have is rather simple:
Is it possible to then assign another drive letter than the original (D:) to the Recovery partition?
The point being that I'd like the user (not me) to be able to use drive letters C:, D:, and E: (with Recovery being e.g. R:), so that she is not confused by, and always has to think about, having to "skip" D:

On this forum I found some statements saying no it shouldn't be done (because then the F11 boot into recovery won't work any more), while others say yes, it can be done with no ill effects.

Any "authoritative" answer to this?
Would it even be possible to remove any drive letter from Recovery, so as to make it "invisible"?

Thanks for any tips!

A:Assign another drive letter than original (D:) to Recovery partition?

Hello Tronje, and welcome to Seven Forums.

The Recovery Manager in Windows 7 and at boot/startup (F11) uses this Recovery (D) partition to start the factory recovery process. (in Windows 7) HP Omni 220-1100 Desktop PC series*-* HP PCs - Performing an HP System Recovery (Windows 7) - c01867418 - HP Business Support Center
(at boot/startup) HP Omni 220-1100 Desktop PC series*-* HP PCs - Performing an HP System Recovery (Windows 7) - c01867418 - HP Business Support Center
Removing the drive letter from the Recovery (D) partition would cause you to no longer be able to open the Recovery Manager in Windows 7. I'm not sure if at boot/startup (F11) would still work or not. You would have to test afterwards to see. If not, then you would need to add the drive letter back.

Changing the drive letter of the Recovery (D) partition could cause you to no longer be able to open the Recovery Manager in Windows 7. I'm not sure if at boot/startup (F11) would still work or not. You would have to test afterwards with both methods to see. If not, then you would need to change the drive letter back to (D).

Hi Guys,
My sister has just brought a Dell laptop, (not sure which model), which came pre-installed with windows vista.
The hard drive has been partitioned into drives "C" & "D" - drive "D" contains the system recovery data and is called "recovery disk".

I need to change the drive letter of "D" to something else as they have some software that only runs from CD and will only run if the cd is named drive "D", so I would like to rename the "D" drive to "L" and then rename the cd drive to "D".

I know how to change the drive letters but I'm concerned that in renaming drive "D" the recovery programs won't be able to work if she ever needs to recover the system.

Does anyone have any ideas about this please?

After partitioning a hard drive with Partition magic, the two partitions were labeled D: and E:
The boot partition was D:. I used the option to change the boot partition to C:. The software showed a warning that renaming the boot partition might result in not being able to boot. I went ahead reasoning that, at worst, I would have to use a CD to reboot. Well, now the computer won't start (I don't mean won't reboot. When I hit the power button the front power light goes on and stays on, the power supply runs, but that's it.

Any ideas?

Okay so I managed to figure out all my problems with my partitions and my computer not starting and I am finally at the last step. I have a partition made specifically for Minecraft with a smaller cluster size so it runs faster...

Now I would like it so this drive has no letter so everyone doesn't see the Minecraft drive on there accounts (in-case they say whats that oh delete etc...). So how can I create a shortcut to the launcher in this drive without allowing the drive to have a letter???

Hello all,

I've been trying to find a way to hide my swap partition, but all available information on doing so either leads to group policy editing (which only has various combinations of the drive letters A, B, C, D, E for hiding), drive letter removal (which is an untenable solution given that the swap partition is only usable with a drive letter to tie it to), or registry editing (which is as untenable as the other two).

I have attempted all three with no perceivable solution.


For reference: My swap partition's drive letter is S:

My first post here so I hope I am in the correct place.

Here is my problem...

I installed Windows 7 Pro 64 bit on a new Seagate 1TB drive. During the Windows 7 install I created a 250GB partition where the Windows files would be installed. I also left an unallocated partition that I would later use as a data drive (for storing music, videos, docs, etc).

As normal, the Windows 7 installer stated it would need to create a system partition where the boot files and other mysterious files would be stored. Indeed, after installation it had created a 100mb system partition (which I believe is normal).

In Windows I used the Disk Management utility to make the Unallocated partition useable. As a result I had the following partitions:

System partition (no drive letter assigned)
C: Boot and Page File partition (where Windows is installed)
D: Data partition (where music, videos, docs, etc will be stored)

So far all is well However...

What I needed to do was follow the simple procedure in the following link to move my C:\Users folder to D:\Users...

The drive letter of my boot/active Win7 partition should be C:, but in my case it isn't; the boot/active partition drive letter is F.

I've tried to move heaven and earth to change the drive letter of the boot partition but nothing works.

So, aren't there any apps, tools or utilities to change the drive letter of my current boot partition?

Thanks in advance,

A:Changing Drive Letter of Boot/Active partition

Nothing that I know of. My original Win 7 installation was "E" drive. I had considered things suggested but finally decided to let it be. It doesn't matter to Windows what the drive letter is, everything works regardless of the drive lettter. I later installed Windows 7 on an SSD drive, with a clean install (and the SSD drive the only drive connected during installation) and now back to the "C" drive.

That is not a problem at all. Unless you have a big problem with those letters, I would leave it as is. But you can change the drive letters in Disk Management (not C though).

I switch on my computer typically as every morning. This time I lost my extended WD Passport 80 MB. No letter drive.

I check in Device Manager. Disk is recognize, but shows
Type - Unknown
Status - Unreadable
Partition Style - Not Applicable
Capacity - 0 MB
Unallocated Space - 0 MB
Reserved Space - 0 MB

Looks like a Master Boot Records gone. Addictionaly it shows me FAT 12 .

I have no idea what's happened.

When drive starts make it sounds like a "turn few times". I didn't hear it before. Is it mechanically corrupted, or just lost partitions ?
