Only folder currupted. What to do best?

#1 Post by kawe »

Hi everyone, :-).
My name is Stephan, I am German and though I am new to this forum I am not entirely new to TestDisk.
I'd prefer to post my questions here in the English forum because I noticed the chance to get a reply is much higher here.

Here my case:

I have got an SD-card partly used for taking photos but also for exchanging PC data from office to home and vice versa.

When I watched a recently taking movie on this card on my notebook at home, a loose connection, an eletric pulse or something like this has appeared for a moment ...
Whatever happened, the file system has been partly demaged in a very special way I have never seen before:

The stick *can* still be mounted and accessed. The root folder and all other data are intact except one folder:
When openening the DCIM-folder (containing the photos and movies from my camera) I don't get its content shown but only one single big file with a cryptic name (like USB[@sdfsödlkö#23²\f...).

I have already run PhotoRec for a while in deep mode and the first results are very good. Pictures and movies can be restored (though the movies are segmented in the two ftyp- and mdat-parts that can easily be concatinated).

Here my question:

As the files have *not* been deleted and the patition table and even even (most of) the allocation table an directory structure are ok - is there a faster or even better (filenames) safe way to restore the lost data in this special case?

Stephan

You can use chkdsk under Windows as administrator to fix the filesystem.
See https://www.cgsecurity.org/testdisk.pdf chapter "Repairing filesystems from Windows".
Sometimes chkdsk fix the problem by removing all corrupted directory entries (~ all files), so you may want to keep the files recovered by PhotoRec for the moment.
