bash: fsck: command not found

[chrls]

My PC is running Knoppix 2.78 and for some reason the file system has errors on it. It tells me to mount the hdd read-write, so I do so, then it says "run fsck" so I do so, and it tells me "bash: fsck: command not found".

What am I going to do? Someone please help me...

When does it say to mount hdd read-write (Sure it don't ask you to mount it read only?)
You don't give mutch info on your problem!

A quick solution is to use a knoppix cd to boot from and then do: su fsck /dev/hdd

Nevermind, I fixed it.

I used /sbin/fsck <filesystem> to fix it.
