Changed RAID one to single and now dead

#1 Post by drewvonadasmith » 21 Oct 2018, 22:57

Friends,

Following some bad advice, I stopped a RAID 1 array, zero'ed the superblocks, and deleted the array in order to use one of the disks. Now, neither of the disks is readable. The parititions look fine, but if I try to mount the single drive, it tells me I had a bad fs type, missing superblock, etc.

Is there any way to recover this file system?

Thanks,
Drew VS

I confirm zeroing the superblocks was a very bad advice.
Try TestDisk, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit
If "Boot" is missing, choose instead Superblock.
