It appears people continue to have problems with these drives. Sometimes the drive just goes dead, but many times they can be fixed. Here is one way that I know fixed mine, and its fixed several others throughout this forum, but the continued posting the same problem and the lack of people posting this as a solution has made it apparent we need a sticky on it. 1. Find a computer with Windows98 (I think First Edition will work, but I used SE) and then download and install the driver for it (Windows98 requires a driver to read the drive). 2. Plug in the your Sandisk Cruzer. 2b. The drive should appear, try and open it and get all your data off, if the drive doesn't appear there may still be hope (details later). 3. Format the drive as FAT32. 4. Recopy your data back, and plug it into an XP machine, its fixed. Now if 98 didn't see the drive, there is an HP utility for formatting USB flash drives, do a search on these forums for HP and Sandisk and Format and it will probably come up. Try that, if that doesn't work, I'd say there is a 90% chance your drive is hosed.
