FWIW, I've *killed* a couple of drives by doing an idle spindown on my BBS.
One in particular--it worked ok for years of 24x7. Worked ok for months in
the BBS, also 24x7. Then I added a 2 hour idle spindown. Within a few
months--it would no longer spin up unless I shake it. Evidently, being
spundown for extended periods of time, with power still on caused the
dreaded "stiction" problem. Granted, this was an old drive (an 80MB Quantum
SCSI), but still.........

So be VERY wary.
