I have a SanDisk Cruzer 16GB U3 (USB drive) that will not be recognized by Windows 2003 Server (standard edition SP2) running on a Dell Latitude D820. When I put it in, it lights up, the device manager lists it as a SanDisk U3 Cruzer Micro and attempts to load a driver which cannot be found. The USB drive works fine on other computers. It even works (recognized) under a virtual XP computer running on the same physical computer under VMWare workstation ! Although the device shows up as an unrecognized device in the "device manager" (with an "!") it does not show up in the disk manager so attempting to assign a different driver letter for access is not an option.
Does anyone have any clue? Of course SanDisk has no solution...
Some initial troubleshooting which may be of value....
I experience a similar issue with some larger (200GB+) USB portable hard drives. Some work, others do not.
Latest Dell BIOS is installed
Attempted options for both USB 1.x and 2 support in the BIOS (no effect)
Tried with and without the CD ROM drive in place
Removed ISO utilities such as MagicDisk
Tried reformatting the SanDisk on another computer but it had no effect (still looking for drivers)
