Jump Drive 88

I'm attempting to use this as my backup drive KINGSTON FLASH MEMORY using Macintosh's TimeMachine backup program. Only seemed to work for a day now the drive KINGSTON FLASH MEMORY won't even show up on my desktop. Also while trying to copy over a large folder (9 gigs) I "bumped" the drive ever so slightly and the transfer stopped and I got an error. I should have sprung for LaCie Rugged Hard Disk.
