e2fsck 1.39 (29-May-2006)
e2fsck: Bad magic number in super-block while trying to open /dev/sda3

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>


求助高手,怎么处理？

e2fsck -b 8193   /dev/sda3？

这个提示已经尝试了，一样的错误

问题解决了么？下面的可能有用

single# mke2fs  -n /dev/sdb1

这样，让我说的清楚一点：
1. mke2fs -n /dev/sda3, 会输出如上的结果，注意block size 和 superblock backups, 这些参数在恢复的时候要用到。
2 e2fsck -B <block size> -b <superblock> /dev/sda3, 其中superblock就用上面输出的，一个个试试，直到成功。

Good luck.
