Folks,

  Thanks to those who provided answers to my query about "key 880" on disk
validations. Now, on a similar topic:

  I've backed out my LUCAS/FRANCES boards, and am once again running a stock
A1000. I am having problems with the internal drive, which can no longer seem
to read or write the inner tracks on the floppy (i.e. tracks 77-79). I don't
have a sector editor: I discovered which tracks it was choking on by trying to 
format several disks.

  I took both my internal and external drives apart (down to the drive
assembly) and hooked the external drive up to the internal drive cabling:
everything worked fine, including the formatting, so I'm convinced it's the
drive itself. Unfortunately, the two drives have a slightly different physical
layout, so I can't just swap them and bolt everything together again.

  Now, I've called two places around here to determine if the drive could be
realigned, and was told that it was too difficult to do, and that they always
replaced the units. One store quoted me $150 for the internal drive unit, and
another $300! So, is there any PD software for drive alignment? Can it even be
done? How would I do it (assuming access to an oscilloscope, if required)?

Thanks again!

Rob
