AHCI (Advanced Host controller) makes NCQ (Native Command Queing) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible; Vista was the first to offer this feature. The issue with AHCI is it needs to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why Windows disables the AHCI drivers not needed during installation.
I would suggest you to enable AHCI after you have installed the OS if you didn't already have AHCI enable in the BIOS when you installed the OS.

Western Digital Serial Ata Raid Controller Driver Manual
Strangest thing happened after configuring my Windows 7 x64 machine to dual boot XP x64. Everything migrated pretty well and was nearly a seamless connection until this drive came up.
I am running an AMD Opteron dual-core 165 1.8Ghz CPU @ 2.1Ghz with 4Gb of matched dual-channel OCZ ram on an Asus A8N-SLI Premium mobo running BIOS v1303. RAID, game/midi and IEEE1394 are disabled in BIOS. ACPI is S1&S3 compatible. Silicon Image 3114 sata controller with most current driver installed.
Here's where it gets weird. I can read and write to the drive like always on windows 7 boot. When I XP boot though, the drive always says 'Drive is not ready' error. Have run scandisk in win7 and using UBCD. No errors found. Is there such a thing as a hard drive driver? I thought that was covered by the SATA controller.. please help
I have had no problems with my storage media on my win7 boot partition.
