There is actually some hope here. The disk format used by WD was fairly
widely accepted and lots of people made controllers that were compatible
with WD's format.

There are exceptions, of course. Adaptec did their own thing, so disks
written by a controller built around Adaptec's chips can't be read by a
WD controller. DEC's DECmate II and RQDX1 controllers were hand-built
from lots o' logic, and were also incompatible with WD's format.
