Most magnetic materials, and I assume hard drive surfaces, are more
magnetic at cold temperatures, and less so at warm temperatures. So
chilling the drive could make the signal to noise a little better, letting
you recover some data.
As Kevin pointed out, heating the drive up can cause it to lose its
magnetism, and the data with it.
The amazing part of forensic data recovery is not so much in recovering
trashed drives, but in recovering data that has been overwritten. The
tracking on the drive surface is not perfect, so traces of previous data
are still present along the edge of the current track, where they didn't
get erased. Plus there is the difference between a 1 overwritten with a 0,
and a 0 overwritten with a 0, the first being slightly less 0-ish that the
second, so to speak.
Sounds like this could be used to at least double the capacity of a drive.
One author claimed that in principle, there are traces of everything ever
written on a drive, if you have the tools and the patience to winnow it
out.
Sounds like rubbish to me.
