I had 3 bad tracks on my hard drive so I used Disk Genius to fix it,ofcourse the data near the back tracks were wiped out.Then I booted from linux rescue disk and run



xfs_repair /dev/sda1

xfs_repair /dev/sda2


sda1 went through ok but sda2 at some point it says"Sorry,could not find valid secondary superblock" and can't go all the way through.What other method do I have to fix it?






centos xfs

          When you have hard drive errors, it's always better to have the following:




          • a bootable USB running the same OS you're running

          • a hard drive equal to or larger than the hard drive you're recovering from

          • a hard drive to save your valuable data on


          Then you should immediately create a copy of your failing hard drive using ddrescue onto the new one and work from the copy so you can always go back and try again...



          Now that you didn't, you can't any more but I still would take an image at this point in time, because no superblocks at all means that (most of) your data is still there, it just cannot be found and you can still use:




          • TestDisk

          • PhotoRec

          • foremost


          to recover individual files.
