A friend of mine has 2 Windows Laptops, where in the process of moving from an old 2TB storage laptop to a newer 256GB storage laptop, moving files manually (somehow, dont ask me).

They noticed they accidentally removed a 35GB folder full of media files from a very big vacation, including nature photography and some strange GoPro format files. Valuable stuff.

So we took the newer laptop as its fresh, very small storage and not much done after deleting the files.

We used a 2TB backup drive which works well.

Used CloneZilla, exited to shell, mounted the drive with udisksctl and used testdisk and photorec, but with strange results.

1. Testdisk created a “whole” recovery in .dd format
2. Then noticed the “undelete” function in testdisk and manually undeleted all files we found
3. Then used photorec on that .dd recovery

The testdisk undelete files are mostly corrupted, images with missing header files etc. Same as the result of some magic sauce proprietary recovery program.

The photorec results where really strange, everything was intact but only system stuff, cache, icons etc, not a single of the deleted media.

The media are 3000 or more, so this makes no sense, we used the “full” backup from testdisk.

The laptop is off and we have some time, we can also use the older, messier one if needed.

Questions:

• any way to repair these corrupted images and media?
• how to work with this data in photorec? How to export just the deleted files?

I think we should try to use photorec directly with the drive and not the .dd image, which may help.

We used dd and cloned the entire small, new disk to an .iso on the backup drive so we can work with it easier. Does this include all the stuff, also the deleted things?

We will also try scalpel.

Thanks!
