Good thinking. I wonder if the surface order matters
too - thinking
about it, it seems like the majority of failures I've seen have been on
the upper surface. Possibly something to do with the spring loading
arrangement in a typical drive (I'm talking 5.25" here - I don't think
I've seen a 3.5" disk fail in the same way, and I don't normally touch
8" drives*)
... engage brain before posting :) I was thinking of lashing something up so
that the upper head wasn't in contact with the disk at all, reading the bottom
surface, and only then reading the top. Thinking about it some more, the
loading of the head against the surface on both sides is almost certainly
critical, so this wouldn't work :(
