[Gllug] Thoughts on secondhand server guide price

[t.clarke]

I seem to recall reading somewhere that once a disc has been overwritten you
cannot recover old data from it using the drive's own heads/electronics.
Instead you have to use a bit of fancy hardware (STM ?) to examine the platters
directly and endeavour to figure out what was written to the platter prior to
being overwritten.
I also recall that overwriting a disc several times with different random data
rather defeats that approach as well.

I would imagine that physical destruction of the disc is warranted only where
the data is INCREDIBLY sensitive.
