Help with usb pen drive

[innskeeper]

This issue happens most of the time with my pc which is running win xp pro, P4 1.7ghz, 1gb ram. By most of the time I mean every once in a while it works fine. I'll plug the sandisk 512mb pen drive into the any usb port and I get the message "the disk in drive ? is not formatted would you like to format it now?" If I click yes the format window comes up then I get the message "windows was unable to complete the format" "the disk in drive ? cannot be formatted". This also happens with my floppy drive.
Any help would be appreciated.
Thanks

Make sure all your wiring is correct, especially the floppy. Make sure you have uptodate drivers. What OS are you running?

Running win xp pro, wiring is all good, all drivers up to date
