Bad superblock, no success on backup superblocks

I've an external usb3 box with a 3tb hdd, I'm trying to mount it but the system tells me that there's a bad superblock. The hdd has a GPT partition table that is still valid. I've already find some backup superblocks, but I can't mount the filesystem also using them. I've tried to restore superblocks using e2fsck trying all backup superblocks, but I haven't success. With testdisk I can access to the disk, I can see and copy almost all the files on it.

Now, I don't want to manual copy all files (the disk is full, so there are 3tb of data on it), is there a way to recover the bad superblock?

Or is better to use testdisk and manual copy all files to avoid any data loss?

Re: Bad superblock, no success on backup superblocks

First, what is the file system on the partition you are trying to mount?
What is the output of lsmod
What are the output of uname -a and of pacman -Q linux

Modify that last command as appropriate if you are not using the stock kernel.
