Hi, When I installed my SanDisk USB reader I had the same problem. The reader would be recognized but the SD card would not show up. Calling SanDisk support the had me uninstall everything, reboot, install via the CD-Rom the SanDisk driver, then plug in the reader, and then the card. Worked! BTW I'm using Win2K Pro. Wouldn't hurt to give it a try, YMMV
TT
