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/dev/sda6:clean; 6574 1/13118464 file, 26970410/104944580 blocks is corrupt ,and you might try running e2fsck with alternate superblock
e2fsck -b 8193 <device> what would i do to this help me
