[Intel-devsys] IMAGEDISK for MDS 8" SSSD disks

The DBIT adapter does an interesting thing. It counts tracks from 00 and
when it gets above some value, it turns on the "greater than track
whatever" write-comp signal. For some early 8-inch drives, they had no
means to self-adjust for higher bit-density inner tracks. And if you
read the drive manuals, there was no standard track-number among them.
Later drives had the smarts to do this, so no external signal is needed.
If anyone has had marginal data problems that mostly occurred on inner
(higher-number) tracks, this might be a symptom. Any comments?
