This doesn't really answer your question, but if you issue the command "smartctl -a /dev/sdx" and see either a Reallocated sectors count, or a Current Pending sector count that's greater than 0, then you need to keep an eye on the drive. It could be failing. (replace /dev/sdx in the command with your drive's actual device) Reallocated sectors count is for failed write attempts, and that number tends to grow after the count gets larger than 0. Current pending sector count is for failed read attempts, which could be a fluke and might correct itself later. It's not as serious as Reallocated sectors.
