LOL sorry, I assumed you were familiar with
fsck. You need to include the partition:
Code:
$ fsck -N /dev/sda5
[/sbin/fsck.ext3 (1) -- /dev/sda5] fsck.ext3 /dev/sda5
$ fsck -N /dev/sda6
[/sbin/fsck.reiserfs (1) -- /dev/sda6] fsck.reiserfs /dev/sda6
Admittedly, not an elegant solution. Plus I don't know what would happen if you tried it with a non-supported FS; but the -N means "Don’t execute, just show what would be done" so I doubt it would hurt anything.
