Running e2fsck, I get Bad Magic Number

My system won't boot in multi mode. I get the following in Maintenance Mode. (none):/dev # e2fsck -b 8193 /dev/dasda e2fsck -b 8193 /dev/dasda e2fsck 1.28 (31-Aug-2002) e2fsck: Bad magic number in super-block while trying to open /dev/dasda 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> (none):/dev # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/dasda1 2365444 2203616 41668 99% / (none):/dev #
