hdparm [ flags ] [device] are used to set the time the harddisk must be idle, before it spins down.

This sets the idle time to one hour:

hdparm -S242 /dev/sda

Values of -S:
0 Disable spin down
1 - 240 Value times 5 secs (1=5 240=20 min)
241 - 251 Value-240 times 30 min. (241=30min. 251=5,5 hours)
above are special and reserved. Se man pages.

To se if the drive are active or in standby:

hdparm -C /dev/sda

To list disks and there partitions:

fdisk -l

NB 1: Dont set the idle time to low. Spin-up wares the disk out.

NB 2: Don't play around with hdparm. It writes directly in the HD controler registers. You can destroy the disk.
