So have this problem. Have a 500G disk with data that has crashed. I need to recover the data. I used
ddrescue to first create an image and I have recovered 455G to that image.
Now, I do not know what the fs of the original disk was (it was linux and mounting the saved image using ext2/3 gives a bad fs error). So when I use a tool like photorec to recover the data, all the recovered files are renamed and somewhat useless to me -- my data files had specific names.
The disk in hosted somewhere else and I do not have physical access. So what can I do?
I used ddrescue from position 300M as I suspect the problem was in the first 200M or so. Anyway I can recover some useful fs info using ddrescue that would enable me to reconstruct a better part of the file system from the saved image?
