Hi Clinton,
In theory spindown could spin down your CD drive if you find /dev/sr0
in /proc/diskstats (my CD-drive is called /dev/sdc and it's in there).
As mention in
http://code.google.com/p/spindown/wiki/Configuration you
can also specify a device using the name parameter. This way you don't
need /dev/disk/by-id. Like this:
[Disk 0]
name = sr0
spindown = 1
command = [insert your command here]
Then you need to know the command that spins down your cdrom drive.
My CD-drive does this automatically. Doesn't yours do this?
Regards,
Dimitri
