My father has an old Asus G73JW laptop. I believe it's a first generation i7. I had him run HWiNFO because I wanted to make sure his fans were running. It's been overheating due to old TIM. He noticed that it said "failure" on one of his HDDs. I had him run CrystalDiskInfo to double check the SMART status. CDI didn't report any errors. Is it possible that HWiNFO is reporting a false positive?
It is possible that some of the SMART thresholds are set too restrictive by the firmware for non-critical values. I know that CrystalDiskInfo has a certain tolerance for some parameters. But it's hard to say more without knowing exactly which SMART parameter is causing this and what's the actual value.
You will need to check in the main window with the complete list of hardware (a tree on the left side). Find that drive and check the S.M.A.R.T. details.
