Hi,

I had a power problem with my laptop that was forcing many restarts, at one point the partitions were corrupted.

I tried to check the file system using 'fsck -y /dev/sda7' and I could mount the partition, unfortunately the inode table seems missing, as all the files/directories are in lost+found.

It seems all the files exist but in lost+found, I want to try to restore the directory hierarchy, so if anyone can suggest anything that would be great.

I have tried the process from here http://linuxexpresso.wordpress.com/2...ock-in-ubuntu/
but it didn't work on the partitions that I already ran fsck on, but it worked on the other ones that I didn't previously ran fsck on.

So any suggestions?

About 10 years ago I had the same problem but I only had about a dozen file fragments in lost+found. I used a hex editor to examine each file fragment in lost+found and figured out what the files were. Then I restored those files from backup. This could be practical for you if you have a small number of files in lost+found.

I've had this happen twice on systems under my control, but like jailbait only a few files ended up in lost+found. I used a combination of file, head/tail, etc. to figure out what the files were so I could restore them.

The problem is that all the partition content is in lost+found, about 450 GB of data, and there are about 150GB totally lost.

I wish I could tried the fix in the link I posted, it worked on the other partitions which I did not run fsck on, I think when you run fsck on the partition it rewrites the superblocks so you can't restore them later. I will try to look for other solutions during the weekend, if I got anything I will post here in case anyone will have the same problem. hopefully not.

fsck is for fixing the filesystem, not necessarily the files in it.
That's one (of many) reason everyone needs good backups.
