I'd first give Disk First Aid or some similar program a go at it. Start
up DFA first and then insert the disk and scan it. Try covering the HD
hole, also- 800k Macs could format 1.44s at 800k which could confuse a
newer machine. You might be sunk, though, if that's the case, as some
800k drives don't magnetize the disk strongly enough and it is
unreadable after several years.
