Hmm, now this is interesting. It occurred to me to try tacking a bit of aluminum foil tape
onto the interruptor blade to make it cover the optical sensor earlier before hitting the
hard stop. That made the drive seek differently, and then report either "Track Zero
sensor misadjusted" or "Seek error during burn-in or recal". Maybe the
sensor is just knocked slightly out of adjustment? I'm hesitant to move it if
there's any chance that it's in the correct location, but maybe this is worth
experimenting with.
