Hi everyone, and thanks a lot for your work. I have an USB drive with BTRFS, on which I write with different kernel release. Anyway, today I made a copy of one big file, and than powered off the computer with a clean shutdown (Ubuntu 13.10 - 32bit). Now it's impossible to me to mount it (even with kernel 3.12). Here the kernel log: [33109.118337] scsi 19:0:0:0: Direct-Access WD My Passport 0748 1019 PQ: 0 ANSI: 6 [33109.118497] sd 19:0:0:0: Attached scsi generic sg2 type 0 [33109.122721] sd 19:0:0:0: [sdb] Spinning up disk...

Annullato I've got a backup of the harddrive, but I am far away from the last file.
