Windows 7: dismantled 2 disk RAID array (data) corrupts win7 OS on SSD

07 Nov 2010   #11


spyknee, thank you for calling me out on giving up too easily, I found a solution!

I will give further details on my setup.

Mobo: Gigabyte G33M-DSR2
SSD: OCZ Agility 60gb SATA port 1
DVD-RW: SATA port 0
1.5 tb data drive: SATA (designated RAID/AHCI port) 2
1.5 tb data drive: SATA (designated RAID/AHCI port) 3

SSD is plugged into one of the two SATA ports that is designated and setup to run similarly to IDE. It was NOT plugged into designated RAID array SATA ports on the motherboard. So the original set-up was set to run in IDE mode. The computer case has not been opened throughout this. So everything is physically the same.

The RAID array was setup prior to OS installs. Linux/tsktskOS could NOT see array (hence all of this).

I cannot say with absolute certainty whether or not the RAID array had system files on it, because it has since been broken and formatted to two NTFS 1.5tb drives. However, I pay attention to every KB on these drives and I'm certain nothing of system importance was on them. I don't even like seeing thumbs.db on these drives.

The solution can be found here.


open regedit
browse to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
change "start" value from 3 (or whatever) to 0
restart (enter BIOS)
change ports to AHCI
save (reboots)
windows boots up, installs crap

Currently posting from Win7 with AHCI enabled in BIOS. Linux/tsktskOS both see Hard Drives!
