Buff them? Hmm....

I unearthed some enormous (12 platter) disk packs the other day, and
they're in a rather sorry state indeed - full not only with dirt, but
half drowned in water (rusty water in a lot of cases from the central
spindle assembly).

I was figuring they'd only be good for curiousity value, but I did
wonder how much bad handling these things can take. Maybe there's a
chance of there still being data on them. A quick inspection revealed
that the platters were dirty, but not apparently damaged in any way
(they're all in their protective pplastic cases after all)

I suppose if rainwater's left calcium deposits on the surface then
that's going to be rather hard to shift.

I have no idea what system they're for - I've never seen a drive that
would take a stack that big. Anyone have any guesses? (presumably CDC
sent drives that would take something that size to all sorts of
manufacturers though).

cheers
