Some my recommendation is to move this drive to a trashcan.
If it is in the RAID1  and another drive is good - just disconnect it from the RAID, and do dd if=/dev/zero of=/dev/sdX bs=1M to overwrite it completely. May be it will help.

The question is how to do I clear this error so smartctl can continue the scan ?
