Do you have partitions and/or network drives on your desktop? I've had trouble with "collisions" between drive letters and I'm still not sure of the rules - sometimes it seems that a drive letter "sticks" with removable drives across systems. In Device Manager for the drive, from the Volumes Tab click on Populate and see what drive letters it wants to use and a possible collision, then go to Disk Management and fiddle with the drive letters. -- Rgds, George Macdonald
From: Nicole on 6 Mar 2005 03:37 Okay - I have sorted it out! The PC had assigned the same drive letter to the USB drive as to a network drive. I went into Disk Management, (through Control Panel, Administrative Tools, Computer Management) and re-assigned a different (unused) drive letter to the USB drive - problem solved! Thanks for the other posts, which helped me look in the right direction!

They shouldn't stick across systems, but they will definitely stick across time - i.e. if a WinXP system has ever seen a formatted drive it will have the (last) drive letter stored in the registry, which can cause all sorts of confusion later. Usually it seems to work out OK, but sometimes .. -- GSV Three Minds in a Can SC recommends the use of Firefox; Get smart, or get assimilated.

I heard somewhere that the USB mass storage driver doesn't seem to work in a system with more than one hard drive (which is the case for all of my desktops)? Yousuf Khan |
