Hi experts - I need your help. I am a girl groping in a usually men's world.

I would like to be able to regularly put an individual SATA hard disk to sleep. The utility to do it ("revoSleep" ) needs that I replace the SATA drivers with "the standard Windows driver".

(I've installed a WD 500 GB Caviar Blue SATA hard disk, using a Promise FastTrak TX2300 PCI controller, on an WinXP SP2 system, Asus P4S533VM motherboard (SiS chipset)).

Now, what is the "standard Windows driver"? pciide.sys, pciidex.sys, atapi.sys, or all of the above?
And, in "Device Manager", which driver should be replaced? The driver for the Promise Controller (appearing under the "SCSI and RAID Controllers" section), or a driver at the ATA/IDE section?

TIA, Gail

(NB Windows Power Management cannot spin-down an individual disk, only all of them
