If my hard drive reverted down to PIO mode would that cause the S.M.A.R.T. utility to tell me "Primary Drive is Bad...Backup and replace" upon startup? Would the PIO mode make my hard drive run so slow that S.M.A.R.T. thinks it's bad or would S.M.A.R.T. still be correct about the error message regardless of the PIO/DMA setting?
