Relink directories to Main directory?

[mifritscher]

Scenario:

• 1000 GB HDD with about 100k files
• 200 MB defective Sektors
• Bootsector + FAT seem to be ok
• Main directory is broken (had only about 10 Entries)
• Got a complete image from the disk (with dd_rescue, have also a list of defective sectors))

I need a functionality Scandisk from Win98 had: search for lost clusters in the FAT, detect the "highest level directories" (=the ones which are not connected to any other directory) and relink them to the main directory e.g. under found.000. Both dosfsck and chkdsk (from Winedows) can only recovery the leaf files, but not the directories - so the filenames are lost.

Is it planned to add this functionality to dosfsck? Or: how difficult would it be to add this? It need to have a detection of the directories while reading the lost cluster chains (should be doable by a magic detection of the beginning of every cluster chain), creating a data structure which directory links to which, and then link all unconnected directories to the main directory. The "normal" revocery of lost files can be done afterwards.

This looks like a nice feature request. If anybody wants to work on this, patches are welcome!
