This looks to be at the media level, so is most likely beyond fsck. Since you said you can afford to lose this drive's contents, I would suggest using dd to fill the drive with zeros: dd if=/dev/zero of=/dev/sdx where /dev/sdx is the designation for your drive. This might cause the drive to reallocate the bad sector, or to mark the bad sector as good again. Then, run a SMART test on the drive again. If it still fails, then that drive probably can't be fixed. If the SMART test passes this time, you can restore your backups on to it and keep using it. If you do that, be very sure to sync that drive with your other backups frequently, and don't rely on it exclusively. If you don't want to wait for dd to write the entire drive, you can try following this tutorial instead: <https://www.smartmontools.org/wiki/BadBlockHowto> It seems to be old, but most if not all of it still seems relevant as well. You will almost certainly want to run e2fsck -f /dev/sdx1 at the end of this process before mounting the drive. Good luck.
