What would cause a disk to need formatting after it has been working fine.
I use a Zip 100 USB for my University work data and this is the second time I have had it tell me that the disk is not formatted. I have been using this disk for a few months now, during christmass it came up with this message, so I formatted it and then put all the data back (I keep a copy of my data on a separate partition). Now its happened again. Could it be a bad disk?
