Extract and repair corrupt .jpg files due to bad sectors

#1 Post by gekonvoo »

Hi all!

I've managed to clone my failing NTFS hard drive to another hard drive using ddrescue.
Then, I've analysed what files are corrupt due to bad sectors using ddrutility's ddru_ntfsfindbad on the cloned copy.
Next, I need to extract and repair these files from the cloned copy.

Content of ntfsfindbad.log:

Code: Select all

inode=21247  errors=0028  errorsize=126464  FILE   name=./path/to/corrupt_file1.jpg
inode=24402  errors=0031  errorsize=257536  FILE   name=./path/to/corrupt_file2.jpg
Are TestDisk & PhotoRec the right tools for my task?
If yes, how can I extract and repair these exact files?
Also, would it be helpful or damaging to run chkdsk on the cloned copy first / afterwards?

Thank you!

There is no way to find my missing data from the corrupted files but PhotoRec may be useful to find a copy of the lost files or at least a thumbnail of this file...
