Just to expand on what Pascal says....
Code:
--------------------
sudo blkid /dev/sda1
--------------------
....gets you the UUID of the partition.
Then you should use that for hd-idle config and especially in fstab if
you put an entry in there to mount the drive. Without wishing to sound
too much like I'm preaching a religion, please, please please, always
use the UUID rather than /dev/sda1 for any hotpluggable (eg. USB)
device. It might be /dev/sda1 at first boot, but you unplug and replug
it, it could now need to be accessed as /dev/sdb1. Refer to it by UUID
and that won't change. Also, if you do specify an entry in /etc/fstab to
automount that drive partition at boot, use the nofail option so the
boot process doesn't hang, (looking for a partition that doesn't exist),
if you should boot without the drive connected or powered. eg.
Code:
--------------------
UUID=B24CF2094CF1C85D /storage ntfs-3g nofail,defaults
0 0
