I've got an external USB disk running btrfs. I use it for backups, and each time I do a backup I take a snapshot.

However, it's giving me this error now:

parent transid verify failed on 109973766144 wanted 1823 found 1821
parent transid verify failed on 109973766144 wanted 1823 found 1821

Obviously, this is a non-critical disk, but I have a few files on here that aren't available elsewhere. Is there any way to recover data from this disk? Maybe by mounting one of the snapshots as root?
