Its always the same sector with the > error. Just as a note, hard drives now come with a number of "spare sectors" which they map automatically to replace dead sectors. This is done because all drives ship with a few bad sectors. Usually when errors like this show up, it is because the drive is out of spares. Since problems like these tend to accelerate, it is a good idea at least to consider replacing the disk before you start losing data more than a sector at a time. You might consider getting smartmontools and seeing what the drive's diagnostics have to say. Usually that will tell you if this is a fluke or a symptom of a failing drive.
