I'm in the need of reading some data from old 5.25" floppy media (1.2MB).
I lent 2 drives from neighbour institutes at the university and after having
recalled that the
floppies have to be enabled in the BIOS I'm now seeing the fd0 device in
dmesg (FreeBSD 8.0 RELEASE).
I can do a dd if=/dev/fd0 of=/root/fd0.dmp
The select light is lit, the head motor seems to get power but the spindle
doesn't spin.
Possibly a drive select issue. Some drives had jumpers or switches,
some cables have flipped-around wires so the connectors are specific to
one drive or another. If your cabling is straight-through with no funny
business at the connectors, set the drive to DS0. If the cable has
split out and flipped-over sections, DS1 should be set in the jumpers
--but then it depends on which connector is used. ...I think, anyway,
it's been a few years since I've had to use a 5.25.
I tried that with two TEAC drives to no avail.
Any clues what I may have forgotten? The drive is connected with the edge
connector and the end is open.
Does it need to be terminated?
None that I've seen.
