Hard Drive Mode: WD5003ABYX

Options in the Bios:

1-Sata RAID/ACHI Mode [Disabled]
i can change that to:
[Raid] Enable Sata as RAID Function
[Achi] Enable Sata as ACHI Function

2- Onboard SATA IDE Ctrl Mode [IDE]
i can change that to
[Achi] Sata ports works as ACHI Mode
[Raid] Sata ports works as Raid and IDE as IDE

3- Sata Port0-3 Native Mode [Disabled]
i can chage that to:
[Enabled] Sata Port0-3 works as Native IDE Mode
or there is other option.. "... as Legacy IDE Mode"

RAID (Redundant Array of Independent Disks)
If you have a single Hard Drive; RAID will not be of use to you. RAID is an array of disks or hard drives. You can set it to AHCI but then you will want to repair install Windows 7 again. I would just leave it on AHCI. You seem to have an easier way there.
