When I've hit this problem, I'm afraid my solution has always involved another disk. By using dd with the count, seek and skip parameters, I made a copy of the partition with a zeroed section where the unreadable sectors were. I then just ran fsck on the copy and let it sort out what it could. (I eventually stuck the old drive in a caddy with a dummy partition hiding the broken section and used it as a scratch disk for moving videos around.)
