Computer hard drives are connected to the controller on the motherboard of the computer.  A lot of computers today may have the hard drive configured to use the older IDE interface protocol to communicate with the SATA drive.

  2. Right click on the Start DWORD and click on Modify.
  3. Set the value to 0 and click OK.
  4. Reboot your computer and enable the AHCI setting the BIOS.

If you are using a RAID adapter on your computer you may try the following:

  1. Open up Registry Editor and naviage to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorV or the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStor.
