Enabling eSATA compability…..

I bought a eSATA external drive from Astone (ISO Gear 481E), I was not able to connect the drive using the eSATA cable (although was able to connect using a normal USB 2.0 cable), I contacted the manufacturer and here is what was required…


To resolve this issue, enable the AHCI driver in the registry before you change the SATA

mode of the boot drive. To do this, follow these steps:

  1. Exit all Windows-based programs.
  2. Click Start, type regedit in the Start Search box, and then press ENTER.
  3. If you receive the User Account Control dialog box, click Continue.
  4. Locate and then click the following registry subkey:
  5. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
  6. In the right pane, right-click Start in the Name column, and then click Modify.
  7. In the Value data box, type 0, and then click OK.
  8. On the File menu, click Exit to close Registry Editor.
