Win XP Home and Professional HDD Disable Function

Hi there
I have 5 hard drives in my system, but, at most only C and D (2 drives) really need to be enabled, so what I do is disable the other 3 by right click on the drive, select the appropriate drive and in the properties tag, select DISABLE THIS HARDWARE.

When required, just enable it.

Question is, when disabled, is power actually removed off that hard drive, or is there a quiescent current (small current) still flowing in the electronics of the drive that is disabled ??

Many thanks in advance.

No change

There's no change in the power consumption of those drives if you have them disabled in software or not.

Sorry no.

The PC design for that area didn't have such a concept of shutting off the power like that. It is possible the drive might spin down but from full operation to spinning on an average drive is all of 5 Watts. Just spinning on some drives is 1 Watt so there isn't much gain here in modern drives.

Many thanks for the response, in that case then apart from internet security as the drives are shared with another system, there is no mileage in disabling with respect to power saving then.

Thanks again.
