If there's multiple platters there's absolutely zero chance of aligning
them
correctly, even with a machine, it's possible you could swap them and get
the drive to low level format but then you've lost all your data so what's
the point? Even on a relatively small 20gb drive there'll be millions of
bits around one rotation so there's no way you could ever line up more
than
one platter with each other.



Good thought - I hadn't considered that the platters need to be syncronized.
This job is not doable in the average kitchen laboratory....
