How to replace SATA drivers by WinXP standard ones? help

[GailH]

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 at the ATA/IDE section?

TIA, Gail

(NB Windows Power Management cannot put to sleep an individual disk drive)
