I have an external hard disk to which the OS gave the letter F:
Now I wanted to call it Y:
I used the disc manager to do this and apparently it worked.
But when I go to Windows Explorer I see the same disc twice: once as F
and once as Y and both seem to work.
But when I switch the PC off and on again, I just get F again and no Y.
Can please somebody suggest me how to solve this problem?
Thanks

Try this:
1. Re-assign letter Y: to your external disk.
2. Click Start/Run/regedit.exe{OK} and navigate to
HKLM\SYSTEM\MountedDevices.
3. Check if the value \DosDevices\Y: is there.
4. Delete the value \DosDevices\F:.
5. Reboot the machine.

Thank you, I followed your directions but...nothing changed.
Still getting F: and no Y: (although \DosDevices\F: is not recreated).
Any additional suggestion, please?

If \DosDevices\F: is no longer present in the registry then you're dealing
with a substituted or networked drive, not a physical drive. Start a Command
Prompt and type the following commands to find out:
subst{Enter}
net use{Enter}
net use F:{Enter}
mountvol(Enter}

Where does drive F: appear and what does it say?

You may not be able to. I have been told that some external drives are
built to use only certain drive letters, such as D, E, F, G. No other
will work.

Please note that earlier I typed by mistake F: instead of L:
A:...K: are on the internal HD, while W: and Y: are external HD and Z:
is the DVD drive.
Note that both L: and X: are missing in above list.In Explorer I see
both L: and its renamed copy X: (just for this session: after rebooting
X: will disappear)
In Disk Manager I just see L:. Here this partition has no label and no
possibility to format or eliminate it.
May this be a problem of the external HD? (till a week ago I had no
problem with renaming this drive)

I'm getting a little confused with the various drive letters you're dealing
with (F:, L:, X: and Y):. Let's get some clarity by creating a drive letter
report. Paste the lines below into the file c:\DiskParms.vbs:

Dim DType(6)
DType(0) = "Unknown"
DType(1) = "Removable"
DType(2) = "Fixed"
DType(3) = "Network"
DType(4) = "CDROM"
DType(5) = "RAMDisk"

Set oFSO = CreateObject("Scripting.FileSystemObject")
Set drives = oFSO.Drives

LF = Chr(10)

Line = "Drive Type State Label F/S Size Free
Serial"
WScript.Echo Line
WScript.Echo String(Len(Line)+2, "-")
For Each drive In drives
D = drive.DriveType
if D > UBound(DType) then D = 0
Line = drive.Path & " " & DType(D)

If drive.IsReady Then
Line = Append(Line, "ready", 18, False)
If drive.DriveType = 3 Then
Line = Append(Line, Left(drive.ShareName, 13), 29, False)
Else
Line = Append(Line, Left(drive.VolumeName, 13), 29, False)
End If

Line = Append(Line, drive.FileSystem, 44, False)
Line = Append(Line, Int(drive.TotalSize/1000000), 51, True)
Line = Append(Line, Int(drive.FreeSpace/1000000), 59, True)
' Line = Line & "Available=" & Int(drive.AvailableSpace/1000000)
Line = Append(Line, Hex(drive.SerialNumber), 67, False)
Else
Line = Append(Line, "not ready", 18, False)
End If
WScript.Echo Line
Next

Function Append(L, S, n, numerical)
if n < Len(L) + 2 then n = 2 Else n = n - Len(L)
If numerical Then
Append = L & Left(Space(60), n + 6 - Len(S)) & S
Else
Append = L & Left(Space(60), n) & S
End If
End Function

Now open a Command Prompt and type this command:
cscript //nologo c:\diskparms.vbs{Enter}
What do you see?

OK, I can now see what drives you have and what type they are. Unfortunately
this has not reduced the degree of my confusion. Here is why:
- In your first post you said that you wanted to use drive letter Y: instead
of drive letter F:.
- You also said that you could see the same partition twice: Once as F: and
once as Y:.
- In your subsequent post you said that you did not mean drive letter F: but
L:.
- In your most recent post you mention that you want to "rename L: to X:".
What's happened to letter Y:?
- The partition list you posted does not show any volume duplication, which
seems to contradict your original statement.

In view of these corrections and apparent contradictions I am unable to shed
any light on your problem. Perhaps Alfred Falk was correct: That you cannot
change the drive letter of some external disks. I suggest you carefully read
the manual that came with your Trekstor500 disk. You should also tell us
what sort of an external disk it is. USB? SCSI? Other?

Well, I found the cause of the problem: it is the external HD!
I bought a new HD and I was able to change the letter easily!
Thank you again for your suggestions.
