I have a server that died, though the drives appears fine. There are four of them, with a 10GB mirrored volume for the boot, and the rest as a RAID5 array spread across the four drives. When I connect them to my windows 7 box, I can import the foreign drives, and even browse/rebuild the mirrored volume, but it won't seem to touch the RAID5 volume.
Is this a limitation of Windows 7? Do I need to attach them to a box that has Windows Server installed to recover the data?
Update: The drives are software RAID managed by windows.
This is a limitation of Windows 7. Only Windows Server versions support RAID-5 volumes.
You will need to have the same controller that was managing the RAID5 installed in the Win7 box. From what I can understand by your post, just plugging in RAID5 set to a machine without a RAID controller is going to get you nowhere.
