Hi
I'm relatively sure the track alignment is the same
as the 1.44. You should be able to use a 1.44M alignment
disk.
I;'ve never heard of there being different _analogue_ alginment disks
(Catseye disks) for 720K and 1.44M 3.5" drives. Certainly the one Ibought
is good for both,
You won't be able to do a write/read test but you can use
a 720K disk for that.
I wouldn't want to write to any part of an alignment disk. Just in case
the positioner decides to fail and I end up overwriting the catseye
pattern.
