But note also that with how often Ubuntu touches the disk, it will quite
simply never park the heads, even if it is inactive. Actually, the
aggressive APM isn't really the issue (although it will, obviously,
affect the live to some extent), it's more that Ubuntu touches the HD on
a regular basis, thus making any park pointless -- and when combined
with aggressive parking on the drive, this sends the park count through
the roof.
