DMA/PIO Question

Hello everyone,

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?
 
I don't think the interface would cause SMART to do anything differently. My guess is if the drive went down to PIO mode with no reason, something's wrong with the drive.

Does it show PIO in the BIOS, or in Windows?
 
Well the cd and cdrw part of my cdrw/dvd combo drive stopped working (DVD still works however). I read that after six errors it will start reverting the DMA settings down to PIO which is what could cause the failure. Right after the CD/CDRW failure, I rebooted and got the SMART error message "Hard drive bad...backup and replace" and it is running extremely slow...im not at the computer now so I don't know if they did revert to PIO, if the drives are on the same IDE channel, or if that even matters...or if it's just a coincidence that the CDRW stopped working AND the hard drive went bad at the exact same time...
 
UPDATE - Fixed cdrw drive by dissassembling and cleading the drive, got all the dust out and used alcohol and a q-tip on the lens...Hard drive is still bad and computer overheats when gaming...Do you think the overheating could be a result of my bad hard drive? The heat isn't coming from the hard drive but is it possible that the processor is being overworked trying to process the bad hard drive?
