run
Code:
mke2fs -n /dev/discs/disca/part3
and use one of the superblocks in
Code:
e2fsck -b [superblock-here] /dev/discs/disca/part3
The e2fsck will run a long time on the router. I suggest you repair the filesystem on an other machine, by attaching the pen-drive there. The procedure is the same, but the device number may differ as you may have connected several pen-drives.
good luck
