Segmentation fault on Rebuild BS

#1 Post by armifer » 23 Aug 2017, 17:39

Hi ppl! How are you?

This is my first post and first I wanted to thank you for all the effort you make.

Thanks to testdisk, I have fixed several old hard drives, which were in RAW format.

This time I have a Hitachi 500gb hard drive that is failing on "Rebuild BS" with an uncontrolled exception. In addition, it is always the same sector.

I'm running testdisk on ubuntu desktop liveCD.

I leave a catch of error so that you see the case:
