Extreme shock when HD hasn't moved

[shawn]

I've got an IBM HD that recently had some bad spot appear. I ran the
Drive Fitness Test to recover the bad sectors. It reported that the
errors were due to Extreme Shock. The only thing this system doesn't
move so I can't see why it would report an error due to extreme shock.

Now after using the DFT, and scandisk on all of the partitions on that
drive it appears that everything is fine. I've been able to use the
drive and have seen no more errors. So my question becomes how likely
is this problem to become worse? It hasn't in the past few days so my
hope is that it won't. Luckily the files on this drive are replaceable
so if it does happen to die it won't kill me. I'm hesitant to replace
the drive if everything is working well.

It could have got that before it was installed.

Some versions of DFT can tell lies about that too.

If its an older IBM GXP drive, very likely indeed.

There a full legal class action about those duds.

It hasn't in the past few days so my hope is that it won't.

If its an older IBM GXP drive, I'd replace it anyway.

Maybe misdiagnosis of another problem? However shock-related
problems are pretty serious for HDDs. My guess is that while the cause
is misdiagniosed, the damage is not and thet the drive has some serious
problem.

Shock is a sure HDD killer. Whatever the problem is and whatever it was
caused by, the drive is very sick now. Very likely to become worse.
This might be a good time to do backup, as long as the drive is
still responsive. If it is a "Deathstar", the symptoms are likely to
grow worse until it can take forever to read from the disk.
