Recovering files from a damaged software raid
Posted: 29 Sep 2012, 16:25
* I'm cross posting in the Partition Recovery forum, because I'm desperately trying both.
I have 3 1.5TB drives in a Linux software raid 5 array. While I was copying files from it, I started getting I/O errors and discovered the array had dropped to only one drive. There doesn't seem to be anything wrong with any of the drives, so I re-created the array fine, but the filesystem is damaged,
fdisk -l /dev/md0 : Disk /dev/md0 doesn't contain a valid partition table
When I run photorec, I thought I was saved because it began finding thousands of files, mp3s, pictures. The problem is the files were all garbage, they were tiny pieces of files with obfuscated file names. I can tell my data is still in there somewhere, occasionally there's a file that's small enough that I'm guessing it didn't get split over the drives, like a small little jpg that's an album cover, that tells me my data is still there! But photorec can't seem to piece the files together properly. Is there anything I can do to help it piece the files together better?
I didn't save the session file, It ran for like 12 hours and said it was going to have to run for like 30 more, but since all it was doing was turning up junk I cancelled it. But if there's any information that might be helpful in that file, I can start it again.
