Stop spare HDD from spinning when not in use

Specs: Windows Vista, 2.33GHz/ 3 GB
I have a second HDD in my computer that I disable when not in use (once a month I make a clone of the primary HDD onto this drive). When I disable this drive it keeps on spinning. Is ther a way to stop it with out having the case open and unpluging the power each time. I have Windows Vista Home Premium machine with an Intel Core 2 Duo E6550 @ 2.33GHz. Thanks for your help.

If you're looking for a way to save energy, then you could mount a switch of some sort (to disconnect power to the drive) on the outside of the case; but realize that a lot of hardware failure occurs when power is applied (and sometimes removed) from a device.

I would like to save energy and wear on the HDD. Could I do it with software instead of hardware? I could install a switch as you suggest, but I'm leary of the power up and power down you speak of.

The amount of energy you will save from powering down an otherwise inactive hard disk will be tiny. The power is used when the hard disk is reading and writing, writing more than reading.

I wont do a lot for wear ether. either. Most of the wear on the drive spindle takes place during start up when it is cold and is using a lot of energy to bring it up to speed. Once the disk is up to speed the wear and energy consumption is minimal.

If you only use the drive once a month for backups you would be better taking it out and putting it in an external enclosure.
