|I would love to get my hands on a floppy disk from 1903! It would be worth a fortune.|
I take it you meant 1993. If that is the case I think you can wave good-by to the data on these disk. Floppy disks were never that reliable at the best of times and one that is eighteen years old is going to be past its best.
You could try a different floppy drive is you have one available as sometime heads get slightly misaligned and make it impossible to read the disks.
