How to backup a disk with crc errors?

1

Hi,
I follow these howto to recover partition, because when I’m trying to make a backup image of the disk gives an CRC error:

When I execute scrub_disk.bat and I’m trying to repair the sectos it says me:

So it’s impossible to do the backup of the disk. Anyone could help me please?
Thanks and sorry for my English!

Does finding out the damaged files and deleting them work?

Hi! No when I delete files and then I execute another check with scrub_disk it finds others sectors :smirking_face:

Is it possible to use a live linux and then do e.g. badblocks -nsv /dev/sdb ?
