One of the key things I've discovered with higher quality drives is

Which is why you can buy drives that doesn't spin down.
Ultimately Linux itself wasn't the cause, the hard
drive itself just
defaulted to a very very dumb power management mode. The default power
management mode might not have been as bad with a fat32 or vfat
filesystem, but filesystems such as ext2/ext3 constantly want to
update atime, so with my drive it turned out the heads would
retract/reload roughly 1.71 times per minute.
Doesn't most people mount ext2/ext3 with "noatime" ?
