[root@ns sbin]# ./fsck.ext3 /dev/hda3
e2fsck 1.23, 15-Aug-2001 for EXT2 FS 0.5b, 95/08/09
/dev/hda3 is mounted. 
 WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.
 Do you really want to continue (y/n)? yes
 Couldn't find ext2 superblock, trying backup blocks...
./fsck.ext3: Bad magic number in super-block while trying to open /dev/hda3
 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>
 이거 복구할수 있는 방법 없나요?
부탁드립니다. 제발 ㅜ.ㅜ
