I had a similar experience. After getting some advice, I managed to fix the
problem by using Norton's Utilities to check the FAT. The first value of the
FAT should be the Hex value F8. Something had changed that, so I kept getting
the "Probable non-Dos disk" message. Changing it back to F8 solved the problem
without having to do a low level format.
Good luck!
