Or the band saw. Half should be good enough, quarter if you are
paranoid.

Not if the platters are made of glass.

Better than 90% are aluminum. Of all the drives I've destroyed over
the last 20+ years, I've never run across one with glass platters.
Wer're up in the hundreds - ranging from full height 5 1/4" SASI
drives to 2 1/2 inch sata drives.


Hmm ... never attacked any more serious ones -- e.g. the 8" SMD
interface drives like the Fujitsu M2312K, or the 10" SMD interface ones
like the Fujitsu Eagle, or even the 14" washing machine drives (also SMD
interface).

And there were even some with hydraulic head positioners, or
with many fixed heads with up to 4 foot diameter platters. :-)

Enjoy,

In 1975 or '76 I was working in a machine shop for the first time. I
would work 3 months straight 10 hours a day (really! I was young!)
doing the turning and boring work on cast iron motor housings for IBM.
The cycle time was just under 15 minutes each so I made 40 per day.
I'd get a couple months of 5 and 6 day weeks and then another run of 3
months on those damn castings. I only found out years later they were
for big magnetic disc drives. I think they were for either the 3330 or
3340 drives.
