So... About 160 hours ago your disk failed to read one sector of the disk. The recent self-test seems to indicate that the disk has been successful in reading the entire disk surface, but I'm not sure that I trust this. I'd keep an eye on the disk, and if at some point in the future it fails (again) to read a sector, you'll notice another entry in the disk error log and the pending sector count go up by one again. If this happens, get the Quantum/Maxtor SMART disk utility, and run it. It may be able to force reallocation of the bad sector.
