Windows added additional drive letters to existing drives

[conner]

I have an interesting problem. Unique as I cannot find any other example out
there.

My computer has 4 physical hard drives.

Disk 0 = d:
Disk 1 = x:
Disk 2 = p:
Disk 3 = c:

D: is where my %userprofiles% are located.
Example: D:\Documents and Settings\Administrator\
Example: D:\Documents and Settings\user1\
Example: D:\Documents and Settings\user2\

X: is where the “my documents†are re-mapped to for each user
Example: X:\user1\My Documents\
Example: X:\user2\My Documents\
Example: X:\user3\My Documents\

P: is where the programs get installed to.
Example: P:\Program Files\Internet Explorer\

C: is the system partition where windows exists.
Example: C:\WINDOWS\system32\

I have a DVD drive assigned as F:

I accomplished the above setup using unattend.txt and a winnt.sif during
setup. Splitting up the OS across separate physical drives results in
superior performance. An added benefit is quicker reinstalls. I have used
this config for years and on multiple computers without any problems.

Yesterday I tried to install Roxio Easy CD & DVD Creator to figure out how
to take an movie.avi and burn it to a DVD that is watchable in a normal NON
pc DVD player. The install went smooth but I got an error while trying to
run the main Roxio program. I uninstalled and rebooted. Shortly after the
reboot I tried to access “My Documents†and it said it was unavailable. I
opened up my computer and X: was missing but I gained two additional drive
letters. I now had a G: and H: drive. I can access G: and H: the same as D:
and P: through explorer.

Drive 0 = D: AND G:
Disk 1 = null until I went into disk management and manually assigned it X:
Disk 2 = P: AND H:
Disk 3 = c:


The view inside Disk Management is even stranger.
Disk 0 looks normal showing (d
Disk 1 does not show the drive letter X:
Disk 2 is normal showing (P
Disk 3 does not show the drive letter C:

How do I remove the G: and H: drive letters assignments and get the Disk
Management back to normal.

I used tweakUIXP to uncheck the G: and H: drives and the result was their
removal from being listed under “my computerâ€. Disk Management still is not
showing the drive letters for my X: drive even though I can access X:. Same
for C:.

The tweakUIXP is a temp fix as I know windows is still broken as it still
wants to have two drive letters for a single disk.

Please advise.
Thank you

You can delete mountpoint by means of the mountvol command:

mountvol X: /D

Remounting with mountvol is a bit unhandy, my tool ReMount
makes it easy:

remount X: Y:

But I suspect that Roxio has screwed up something and
that the problem will be back after next restart...

HKLM\system\MountedDevices\ is interesting. I have quite a few Volume
entries that I cannot make sense of yet. I also had some \DosDevices that
listed the drives letters. I removed the obvious \DosDevices\h:,
\DosDevices\g: but the drive letters came back upon reboot

\??\Volume{020cb79c-c996-11dc-b7f5-806d6172696f}
\??\Volume{020cb79d-c996-11dc-b7f5-806d6172696f}

how do I translate these binary data keys to see if they are causing my
drive letter problem?:

chkdsk seems to always want to run on my D: drive. I let it run its course
and also had it do a full manual chkdsk upon reboot. The volume seems to be
flagged as dirty. It does not find any issues.
