If you've saved info on a disk from 98 or 95 or NT, it may not open on XP. I've had this happen to me before. If you saved it on 2000 however there shouldn't be a problem. Windows 98 and 95 use completely different file systems then XP and 2000, which translates to the floppy storage somehow. Its either this, or you saved a corrupted file on the disk and its run its course. Or you could have damaged the disk somehow. My guess though is that you saved the files on a Win98 machine. When Windows says "This disk must be formatted etc..." it may mean that it isn't seeing the file system its supposed to.
