I've just recently picked up a 3.5" disk drive (Sony MP-F52W-50, out
of an old HP 9122 dual drive "box"). I have the CSS XF551 conversion,
which should allow me to use this drive. But it's not standard. The
Sony expects power (+12, +5V) on the 34-pin cable, not four separate
pins. So I wired it up correctly. Now at least the drive spins up,
but I am unable to read, write, or format a disk. I have the slide
switch in the right position (otherwise it doesn't even spin up on
power-up, or when I send a command to the XF551), and I'm only trying
to use DSDD (720K) disks.
Can anyone point me to schematics or documentation on this Sony unit?
Or maybe the standard 34-pin connector's pinout?
Thanks in advance!
