Hi.
I'm an idiot.
My ext3 root filesystem became corrupted recently due to power outages. Like a moron, I don't have a backup of my most important files.
I've used dd_rescue to make an image of the disk on a portable hard drive and tried to fsck the image. The root directory was lost, so the result was 65 GB of files in /lost+found with useless names.
I ran dd_rescue again and looked for alternate superblocks. I couldn't mount using an alternate superblock. I tried to use fsck on an alternate, but once again it wanted to resize the inode, so I quit rather than continue. (dd_rescue takes six hours to image my disk, so I thought the low probability of success wasn't worth the effort.)
It seems to me that I'm out of my depth here. I either have to take the disk to a data recovery specialist or find an ext3 guru in the area to help me out. I'm willing to spend money to recover the disk, but I thought that someone who really understands ext3 could produce a better result than a data recovery shop. I also thought that there must be such a person here in the Boston area.
If you have any suggestions or are willing to help me out, please let me know.
Thanks, from a desperate moron.
