Recovering a damaged ext3 system, where to start?

I would recommend to backup you brother's harddrive fist in case 
something goes wrong. If you get ssh to work, maybe you can use rsync to 
backup his data to your machine (?!) after mounting the broken fs using 
knoppix (if that's possible). Another possibility is to make an 1:1 copy 
of his harddrive to another for example external harddrive by using the 
dd command:

$ dd if=/dev/hda of=/media/sda1/hdd_image

(change the drives accordingly)
In case something messes up during the fsck the image can be copied back 
to his harddrive..

I once had the same problem and everything went fine with fsck, but in 
case data that ought not to be lost is stored on you brother's hdd, a 
backup is a reasonable thing to do.
