Dear Ted,

ensure that there aren't any unnecessary daemons like crond, sendmail,
ftpd running.
A non-journaling file system is also a must.

If you want to get the bad boy who spins up the disk, simply look in "top"
which processes have increasing accumulative cpu time. Even some megabytes
of used swap space can be a reason for a constantly running disk.

My expierience is that the drive holding the root + swap partitions is
really hard to get spinned down while the other drives happily spin down.

Find the bad boys!

Best regards,

 Stephan
