I had a WD 80gb that would silently write erroneous data whenever it
got hot. After significant activity, archives or large files that I'd
just copied to it would fail their checksums, and fail the comparison
with the originals. I never detected any errors after the data was
(finally) correctly written. I now avoid that brand like the plague.
