Cannot mount BTRFS disk: “open_ctree failed”

Yesterday, I cannot mount my movable disk formated with btrfs. The primary errors are

BTRFS error (device sdd): open_ctree failed

and

Couldn't setup extent tree

I opened a thread and put detail outputs on SuperUser. I tried btrfs rescue super-recover, btrfs rescue chunk-recover, and still failed to mount it.

The error outputs of btrfs rescue chunk-recover:

vivodo@esper:~|⇒  time sudo btrfs rescue chunk-recover -y /dev/sdd
Scanning: DONE in dev0
Couldn't setup extent tree
open with broken chunk error
Chunk tree recovery failed
sudo btrfs rescue chunk-recover -y /dev/sdd  161.89s user 2496.23s system 7% cpu 9:29:51.66 total

Any idea to recover my disk?
