We have a pc that the floppy drive type was changed. If you went into explorer the drive said it was a 5 1/4 and it is a 3 1/2. If you tried to save to it, it was give you the error "cannot access retry or cancel". I went into setup and the drive was correctly set as a 3 1/2 there. In device manager the floppy disk under disk drives was not there. I finally disabled the drive in setup rebooted the pc then went into setup, set it as a 3 1/2 then rebooted again. This fixed it. How did it's type get changed to a 5 1/4 in the first place and how did the floppy disk get removed from device manager. Could it be a virus? Thanks for any help!
