There was a 'lastdrive' in config.sys and a L: parameter in autoexec.bat
and tweakui could make changes in the registery (all prior to Vista).
From your machine description I sorta assumed that you installed Vista from
scratch rather than upgraded. If you upgraded or transfered your settings
from a XP machine then the transfer may have tried to set things up as the

You could check your current environment variables for funny stuff:
Right click Computer
Advanced system settings
environment variables

Also if the partion/drive is/was compressed then its real drive letter is
suppressed, its state may be partially retained in its current
A drive that was compressed but not properly installed would mess up and
hide letters for drives other than itself!

I think that if tweakui was used to hide the drive then it was really
inaccessable. If lastdrive was how it was done then it could be accessed, it
just didn't show in explorer. That is you could get to it by opening "x:"

HKCU\software\microsoft\windows\currentversion\pol icies that was in XP!!!
Nothing there in my Vista.

Hope you are having fun,

Thanks Freddy & Michael,

Tried your suggestions and still a NO SHOW under "Computer". BUT, I think
the limit on Drive Letters may be the solution or problem.

limited the drive letters visable. Perhaps there is something in Vista of
same function (did
not find it with casual check)."

I removed the drive and added a partition to the external drive. You
guessed it, it did NOT show up! It seems that VISTA will not allow more
6 HD letters. So it would seem that the limit may be the issue.

Now, how do I overcome this???

Hey Freddy,

Been there and tried that. The drive is designated as drive "T" and has
been formatted. Disk Mgmt shows it as Online and Healthy. The drive
up here with no issues and shows in device mgr, also with no issues. NOT
showing under the old title, my computer. Whats next?

Try assigning a drive letter in Disk Management. Right click Computer
(formerly My Computer), then select Manage, and then Disk Management.
can also partition and format there. Once you get there, it's pretty
self explanatory.
