mount: wrong fs type, bad option, bad superblock on

The disk is decrypted, after that I try to mount and it doesn't mount,
this last message appears on the log after trying to mount the btrfs

I plugged it directly by sata and this is what I get from the 3.1 kernel:
[ 577.850429] ata3: exception Emask 0x10 SAct 0x0 SErr 0x405
