Subject: RX02 Problem solved... From: Gary E Kaufman <gkaufman at the-planet.org> Date: Tue, 26 Sep 2006 22:10:26 -0400 To: cctalk at classiccmp.org Tony and others - The head load pad looks visually fine. The head load spring tension appears pretty normal , and the solenoid pulls in nicely. The drive consistently reads the first 10 or so tracks, then tosses various number of errors as it goes further out. I've cleaned the head, and cleaned/lubed the spindle. The track 0 sensor appears fine.

It is indeed possible that the alignment is off - that would probably explain the poor performance as it steps out.

I guess a worn out head would have the same symptoms.

I the 70's I had a neat Dysan digital alignment disk that I used to realign a few SA901 and SA801 drives. Unfortunately I no longer have it. I suppose I could mark the position of the stepper and slightly rotate it in each direction to see if it improves things.

If someone can point me to an actual alignment procedure I'm game - I have reasonable scopes etc here.
