I suddenly suspect it's the S.M.A.R.T. offline scan
http://en.wikipedia.org/wiki/S.M.A.R.T.
A subsequent version improved failure prediction by adding an automatic
off-line read scan to monitor additional operations. The latest SMART
technology not only monitors hard drive activities but adds failure
prevention by attempting to detect and repair sector errors. Also, whilst
earlier versions of the technology only monitored hard drive activity for
data that was retrieved by the operating system, this latest SMART tests all
data and all sectors of a drive by using "off-line data collection" to
confirm the drive's health during periods of inactivity."

Hey, thanks for this link. I had (have?) no idea that my emachines AMD Windows
system is SMART-equipped (if that's the proper tech-y terminology.) I too have
noticed some hard-drive 'behavior' when it's just sitting idle (and off-line).
Always wondered what it could be--thinking there was something bad about to
happen!
I need to read up on this stuff.

I've seen systems where if you have the SMART turned on, as soon as SMART
says "you might have trouble soon", the system says "your disk is dead!"
Which of course 100% defeats the purpose of SMART.
I also have enough cynicism to wonder if randomly sweeping the moving parts
around the drive when it would be better off just sitting still isn't a ploy
to make it wear out faster. :-) Hard to judge on that one - could go either
way.

S.M.A.R.T. warned me my hard drive was about to fail after it failed. I
don't put too much stock in it.

Yeah. I've had it where the machine wouldn't boot because SMART was saying
the drive was failing, and I had to turn off SMART to run the machine. And
since it was just essentially a compute-node with nothing on the drive that
wasn't in the repository, I left it run another 9 months before the drive
eventually did fail.
Pretty useless, IME, also.
