There are some options with smartctl you could try to force the drive to swap that bad sector with a spare one.

A full disk read could also force that. Eg. Try ' dd if=/dev/sdc of=/dev/null '.

But, I usually order a replacement when Smart tests start throwing errors.

I know 3TB is a lot for you to have to backup, but it's also a lot of data to loose...
