이럴때 어떻게 하면 파일시스템을 복구할수 있을까요?
 e2fsck /dev/hda1 실행하면
 에러메시지 :
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
