I don't mind if the system does not > start, but I need to recover some files (pictures basically). Looks like the drive is shot, although I suppose it could be a bad cable. What I'd probably do is run a dd_rescue from a livecd or another system to a second drive, and then try mounting it via "mount /path/to/file /mnt -o loop -t btrfs" or some such. Once you have the image it should be possible to get something back even if it doesn't mount at that point. This, in a nutshell, is why I think people are foolish to not have backups even if they _aren't_ running a filesystem still under active development.
