Hi there, I am currently executing Drive Genius from an external Mavericks installation onto my internal hard drive. The internal drive has been zeroed on all sectors using the Shred option. On last pass, it found and spared 31 bad sectors, and I am currently running a second pass, where it found 15 bad sectors. Should I continue running it until it doesn't return anything? The reason I am so obsessive about these is that Western Digital refuses to honour 5-year warranty under the reason they never received previously defective HDD (and I can't find its tracking number, it was too long ago).
