Recover RAID array (incl. array sequence, stripe size)
Posted: 10 Jun 2017, 16:14
Hello,
I have older 2-disk RAID-0 array created with the firmware-based, Intel Storage Matrix RAID. The individual did not save the configuration and rebooted using the incorrect parameters.
Stripe size is unknown. The data is preserved, as the OS never rebooted. It was a Windows (7?) installation, likely NTFS. I do not have the original motherboard.
Can I use testdisk/photorec to recreate the RAID configuration and partition scheme?
(As this is as much an intellectual exercise as a practical matter, Q:) Would a viable strategy be to identify a largish known file ( > 2 * stripe size) then attempt to reassemble it? (If this in fact would work I will plant such a file in my RAID arrays)
Thanks!
