My drive got corrupt after a thunderstorm. It used to be 1 partition of 2.5tb but now it shows 2 partitions. It's weird because 300gig free space is about how much it had before corrupting, but it was part of the first partition.
I tried
$ sudo resize2fs -f /dev/sdb1
Resizing the filesystem on /dev/sdb1 to 536870911 (4k) blocks.
resize2fs: Can't read an block bitmap while trying to resize /dev/sdb1
Please run 'e2fsck -fy /dev/sdb1' to fix the filesystem
after the aborted resize operation.
sudo e2fsck -f /dev/sdb1
e2fsck 1.42 (29-Nov-2011)
The filesystem size (according to the superblock) is 610471680 blocks
The physical size of the device is 536870911 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort? n
....
Error reading block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes
Force rewrite<y>? yes
Error writing block 537395215 (Invalid argument) while reading inode and block bitmaps. Ignore error<y>? yes
... A lot of these.
I can't use e2fsck -y because the first question aborts if I say "y". If I put a weight on the 'y' key it fails because none of the errors were really fixed.
I asked this question before and tried using gparted but gparted fails because the first thing it does is:
e2fsck -f -y -v /dev/sdb1
giving the same error. The disk status says healthy. There are no bad blocks. This is very frustrating because I can see the data in testdisk and it looks like it's all there. I already bought another 2.5tb drive and made a clone using dd. The next step if I can't fix this is to wipe that drive and just move the data with testdisk, but it seems certain folders will copy infinitely until the drive is full because of symlinks or errors so it's also a difficult option.
sudo fdisk -l

badfile is empty
I also tried changing the superblock with "fsck -b" but all of them are the same.
