3TB Passport very slow

Unfortunately i think it is out of warranty. I tried splitting the drive into two partitions. Still having the same problem as well as on the second partition I am getting a failure notice that says “unused node 23042 not eraced and unused node 23171 not eraced”. It seems I have a few bad sections in the drive that is causing some problems. so, I assume it is time to junk the drive and buy another. Unless one knows how to fix or ingore those portions of the drive?
