Turn that on and it misses steps like crazy... So I need to figure out
what value to use for the track-to-track seek delay... Ugh.
Another thing I just found out: the head actuator stepper motor isn't
stepping properly. Every time I issue a STEP pulse, it seeks out *two*
tracks instead of just one.
So I end up with a 615-track image, which only contains 308 tracks of
valid track data.
Does anyone have any ideas why the drive might be doing this, and if
it's likely to be fixable?
Thanks,
