Warning failed while updating the boot sectors for disk0 partition1
Quit and reboot I think I did what you suggested, here are my notes from what I tried. What's strange is that one tool out there (Get Data Back) can recover the structure of the directories but not the files themselves, and your tool photorec seems to be able to recover the files, but not the directory structure.That makes me think that there should be some way to recover both.My 1TB NTFS drive (not the boot disk) all of a sudden is inaccessible, w Indows wants to format it. I tried running the Get Data Back tool (evaluation) and I get what looks like asignificant portion of the file tree structure and filenames look correct, butall the files seem to be corrupted.I ran testdisk on it and the partition seems OK, but the filesystem is gone: Drive E: - 1000 GB / 931 Gi B - CHS 15200 255 63 Partition Start End Size in sectors HPFS - NTFS 0 4 5 15200 35 3 244189952 HPFS - NTFS 0 4 5 15200 35 4 244189952Is it possible to recover the file system somehow and retrieve filenames and directories?

If you can see your files, choose Write and confirm. It doesn't look like the steps you suggested seemed to do that unless I followed them incorrectly. Filesystem seems damaged."Is there some way I can go in there manually and fix the bytes-per-sector problem?
