I ran testdisk and it suggest me to runThe filesystem size (according to the superblock) is 1220279319 blocks
The physical size of the device is 536870911 blocks
Either the superblock or the partition table is likely to be corrupt!
I tried that without success. I tried other superblock locations and failed as well.e2fsck -b 98304 -B 4096
I can still see the files on the partition using Advanced -> List. I have copied the great majority of the files but would really like to fix this drive. Any suggestions? Thank you in advance.
