Got myself an ancient external 400k mac floppy drive on the cheap that
I'd like to use on my 128k mac -- after cleaning out the old dried
lubricant and getting the drive mechanism running again, the drive works
but will only read/write disks that it has formatted, which leads me to
believe that the drive is out of alignment. How is alignment corrected
on these drives?
Thanks!

Hi
Like any other drive, you need an alignment disk for a 400k drive.
That would be a tough one.
You can always just experiment some. Before moving the stepper,
make sure the track zero is in the right place. After a recal,
measure the distance the head is from the spindle. It should be
close to the same for both drives.
If the track zero is right, try the stepper next.

Thanks for the advice. After a few hours'
fiddling I've got the drive
reading/writing reliably. Now to find some 400k images of mac software
that'll run on a 128k :).
One of these days one of my tuits will be other than rhomboidal, and I'll put
System 7.5 on the 6100 in my storage locker (since that's the last version of
Mac OS that will deal with 400K disks) to run disk copy and create those
images. I still have the original MacWrite and MacPaint floppies that came
with my 128K, along with a lot of other good stuff (like the Banana PC 6000 Jr.
emulator for the Finder, and a CLI that would only run on a 68000).

Cool stuff - let me know if you ever get that done. (Or if you suspect
you'll never have time, I have a IIfx here that's all set up for such a
task, and I'm in the Seattle area ;).
Thanks,
Josh

Untrue. I've both created and read 400K disk images with Disk Copy (and
DART) on various PPC machines running upto OS 9.
This includes some Powerbooks as well as a TAM and and 7100.
You do not need System 7.5. All that's required is Disk Copy and a
SuperDrive or 800K floppy drive. (USB floppy drives will not work.)
If you wish to read the files on MFS you need System 6 (or MFS lives on
OS X).
