Identify corrupted files by bad sector pattern

[Alkemist]

I need to exclude corrupted files from a recovery result.
Corrupted files have bad sector pattern on their hex code.

Someone can suggest a software capable to identify and separate them? (or just delete corrupted)
Thanks

pc3k data extractor has best option for that task.

Yes, true (PC3k non need any external tool).

But I need for data recovered using MRT.
It save good and corrupted files, but can fill bad sectors with pattern.
So to delete corrupted need axternal tool.

MRT's latest version is supposed to split good and damaged files, somewhat similar to PC3000, though it has been reported by some that it doesn't work...it did for me on my test case.

Yes is a new function but:

A: not any manual and not any explenation about
B: Impossible to contact support by skype neither email (never answer).
C: After a lot of testing not only a broken file has been moved to the special folder (!BAD)

So:
I'm unable to use it ? (....ok probably)
It is an incomplete/buggy function ?? ..............

If you have all files copied out, on a good hard drive, you can use any file manager which supports search inside the files, especially if the pattern is text. I use FAR myself, https://www.farmanager.com/ but any other will do. Even Windows Explorer will probably do the job just fine, if the pattern was text.

Total commander can search inside a file, text AND HEX
and deleting/moving/copying those files

Hi

In DE options, in Copy type tab, select black , red and yellow square. Press OK and try to save some broken files with File explorer . The broken files should go to that folder "Bad Flies"

Not sure it's relevant to this particular case, but it might still be useful to someone.

– With ddr_utility, there's a tool called ddru_ntsffindbad which can identify corrupted files based on ddrescue's logfile (after a completed recovery on a volume with unreadable sectors), and the MFT (provided that it could be fully recovered otherwise it won't be reliable). Another tool called ddru_findbad can do the same on non-NTFS filesystems, but I haven't tried it yet (according to the author it's generally less efficient).

– With ddrescue's “generate” function you can automatically identify empty sectors : it will create logfiles marking empty sectors as “non tried”, then you can visualize them with ddrescueview (I used this method to assess the damage on large video files containing unreadable sectors after cloning a failing HDD, as explained here), or fill them with a specific pattern using ddrescue's own “fill” mode. It might be possible to automate the process with a script.
