我重新启动桌面，我的btrfs驱动器没有安装，所以我想我检查了它
btrfsck /dev/sdc1
Check tree block failed, want=68837376, have=1586977943489443072
Check tree block failed, want=68837376, have=1586977943489443072

Checking filesystem on /dev/sdc1
UUID: f0668001-af9e-4101-a029-396436c43f62

我尝试恢复它
btrfs restore /dev/sdc1 /mnt/Quadi7_d/__SIL__/temp/ -ois

我不知道为什么会发生这种情况以及为什么我无法恢复它。这是第二次与Btrfs发生这种情况。但在第一种情况下（使用另一个驱动器）我能够恢复它。
有关如何获取数据的任何建议？
我在Debian Wheezy 3.10-3-amd64 64
