Well, besides shock, heat is still the number one HDD killer.
Maxtor says 5C...55C with no impact on ARR (i.e. warranty claims)
and up to 60C with "acceptable" impact, whatever that means.
If you intend to operate your drives longer than the warranty
period, staying well below the 55C most of the time and
never exceeding it may be a good idea.

Looks like a typical dying Maxtor disk. The nice thing about them
is that the die gradually, i.e. when you observe the first warning
signs (defect sectors that the disk could not hide, or better
steadily growing reallocated sectors in the SMART values),
most data is still intact and you can get it off.

Personal opinion: Yes. But there is a random chance factor involved,
you may have just gotten unlucky or the disk might have been subject
to excessive shock before it was mounted in the PC.

Most likely. When a modern disk cannot hide defects anymore that
is a _very_ bad sign.

Well, I don't qualify. However I have in excess of 50 HDDs currently
running, most of them mounted myself and many Maxtors among them, so
I have non-exoert experience.
