Hello Bruce,

Setting hdparm -S on the device controls the spindown timeout, for example
if your device is /dev/sdb you can set it to time out if inactive for 50
seconds by typing "hdparm -S 10 /dev/sdb" as root. The number after -S is
multiplied by 5 to give you your spindown timeout. Also note unmounting the
drive will not park your harddrive for safe transportation. You will have to
issue "hdparm -Y /dev/sdb" This will park the heads and put your harddrive
to power off mode. The only way to get your drive active again is to
physically power down the drive and then power it back on. This should work
for any drive in any enclosure.
