I recently replaced my old HDD (Seagate 80GB 7200 RPM IDE)with new one Seagate 500GB 7200 RPM SATA (ST3500418AS)
I use the speed fan S.M.A.R.T. to check my HDD status it shows fitness & performance of my HDD above 92-93%
S.M.A.R.T. tests sometimes go overboard.
Your drive is not in the database.
If 2 other tests say the HDD is okay, ignore the S.M.A.R.T. results.
Sorry can't see your image here at work.
Molex to SATA converter is fine.
