haven't really fully confirmed if it's a 1.2M drive. TEAC FD-55GFR
142-U, because I haven't actually come across any 1.2M formatted media.
I've wondered if maybe one of the heads on the D: drive the Sharp PC-5000's
dual disk drive might have some kind of issue (either the REad or Write
head, not sure which) - just since it seemed more likely to end up with
some bad sectors marked when using
FORMAT.COM (whereas on other systems,
the same disk would format fine with no bad sectors).
Teac FD-55GFR is a 1.2M drive that can also be used as a 720K 5.25" drive.
(FD-55G is 1.2M; FD-55F is 720K)
