If you got backup hard disks(ATA) in your box and you do not want them
spinning all the time,and want to turn them off (shut them down,make them offline) to save power,here is the tool:
hd10w.exe // it means "Hard Disk 10 Watt" ,
It is a command line tool, you had to run it in cmd window or in batch file.
Currently, I only used it in my own box.
Examples:
Disk1 80G c: d: e:
Disk2 120G g:
Disk3 250G h: i:
hd10w off g: h: // to turn off g: and h: volume
hd10w off monitor // to turn off your monitor(display)
hd10w on g: // to turn volume g: back online
hd10w off h: monitor // to turn off g: and shut off monitor
If you can not turn volume off please check if there are files opened
on that volume and you have access rights.
If you can not turn volume back online, you can reboot or use device manager.
Tip: if a hard disk got two volume like (e:, f:) and "hd10w off e:" fails,
sometime you can try to use: "hd10w off f:" instead

!!! WARNING !!!

hd10w is in beta testing!!
and only tested on my Seagate PATA hard disk in Windows XP sp2,
so use it on your own risk, I am not responsible for the data lost
or hardware failure!
