I have an old 27 gig ide hdd that has the smart feature tripped. I have marked and remapped the drive, as the bad sectors were at the end of the drive, I was able to partition the drive to enable the first 25 gigs to be used. I use this drive to test donated computers, and do not intend to put into anything to stay. It just annoys me to have to see this (smart tripped ) message. Any ideas as to how to reset the smart feature?
