These instructions assume your workstation is equipped with an Intel chipset, no responsibility is taken for any loss of data.

To convert a running (ie previously installed) Windows 7 installation from AHCI to software RAID do the following:

  1. I’ll assume you have a recent backup of your system, it not do it now.

  2. Set HKLM\SYSTEM\CurrentControlSet\Services\iaStorv\Start to 0 (zero) - it’s a DWORD value.

  3. Install Intel Storage Matrix Manager and drivers (look on Intels web site)

  4. Reboot.

  5. Open Intel Storage Matrix Console, Select Create RAID from the Actions Menu. It is possible to migrate the system drive to a raid system, follow the wizard in the Intel Storage Matrix Console.

  6. Wait for the raid array to rebuild - this can take hours :)
