Hi Paul,

I've seen this problem before. It is caused by the fact that you have 'ghosted'
the installation of NT from another machine, and that machine had drive letter
assignments already in place.

To elaborate:

When you assign drive letters using Disk Administrator (as opposed to allowing
the 'natural flow' of letters with no overrides) a new key at:

HKEY_LOCAL_MACHINE\SYSTEM\DISK is created.

This contains a series of subkeys in the form:

\Device\CDRom0 = "Letter:"

and a key called 'Information' with binary entry associated with it.

The CDRom drives etc are assigned by the first style of terminology, while hard
disk partitions are stored in the 'Information' key.

The solution to your problem is easy - using RegEdit REMOVE all the subkeys
under the 'DISK' key EXCEPT the (Default) subkey. Then reboot the system - the
drive letter assignments will revert to 'natural flow' letter assignments. If
you now go back in with Disk Administrator and re-assign the drives the way you
want them, the subkeys are re-created, and this time the assignments WILL stick !

BE ADVISED that the system (the partition with NTLDR etc..) and boot (the one
with NTOSKRNL etc...) partitions CANNOT have their drive letters changed or
assigned under normal circumstances. If they are not the correct drive letters
with a 'natural flow' assignment (ie: the order in which drive letters are
assigned if you don't override anything) then removal of the 'Information' key
may result in an unbootable system. There are tricks to change this behaviour to
- but they can be complex and carry an element of risk. Please ask if you need
further information.

Hope this helps.

Calvin.
