If so, how would I go about doing it There is a bad block at the beginning of the inode table. Reconstructing the root inode is easy, but the problem is that the root inode must be at a fixed location, and you currently have a bad block located there. It might be possible to force the disk drive to use another block from its spare pool, but very often one bad block is just a prelude to another, and the value of the disk drive (< $200) is often in the noise compared to the value of the data stored on the disk drive (priceless). So the safest approach would be get another disk, and use dd to copy the filesystem to another partition: dd if=/dev/hda4 of=/dev/hdb4 bs=1k conf=sync,noerror Then run e2fsck on the new disk; it will create a new root and lost+found directory, and move all of the inodes that were in the root directory and home them in the lost+found directory. You should be able to reconstruct the names of each of the directories in the lost+found directory from their contents.
