Adding harddrives and RAID

I have to confess that I really like the Windows 7 OS, 64-bit professional or ultimate.

One of the things that I found out however is when you have a computer where you did not install RAID from the beginning it seems to crash when you switch the BIOS to RAID. And if you try to install RAID drivers in Windows 7 it says RAID is not activated. Catch 22? That sucks.

So you can try this, which worked wonders for me:

  1. With RAID disabled, boot into Windows and start Regedit.exe
  2. Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\iaStorV
  3. In the right-hand column, you should see a value named Start. Double-click this entry and change the data from 1 to 0.
  4. Reboot with RAID enabled – Windows should load just fine. Now install the Intel Matrix Storage Manager as you usually would. This time around, it should detect your hardware and install without any issues.

Now if you try this, do it at your own risk.
