umm...yeah, no...disk errors do show up and then go away. I have wiped disks before, and then run test software (starting with chkdsk and going from there. In particular, I use AOMEI Partition Assistant Pro for surface analysis) that show the HDD is healthy. A repartition, reformat and clean install of the OS result in a usable drive. I've done this, myself, on multiple "bad" HDDs that have gone on to live long, healthy lives.
