The installation for 12.04 kept failing, and the solution was to have the installer ignore the btrfs partition that I have previously been using for /home.

Now that it's installed, I've been trying to get it to mount the btrfs partition so that I can access my 70GB of files. It won't mount, and btrfsck errors out with the following three lines:

parent transid verify failed on 31302336512 wanted 62455 found 62456
parent transid verify failed on 31302336512 wanted 62455 found 62456
parent transid verify failed on 31302336512 wanted 62455 found 62456

Can someone please tell me how to get this partition working? I've read online that I can probably recover the data using btrfs-restore, but I can't find that program anywhere.
