GUYS -- SMART UTILITY IS *TERRIBLE* AT INTERPRETING THE DATA IT READS.
It screams bloody murder and FAILURE when it shouldn't. One of my drives was once two degrees hotter than the manufacturer thinks it should get. This was in the dead of winter, when the heating in my room was maxed out, so the drive's temperature was that high because of the ambient temperature in the room, not because the drive was malfunctioning. (This was six months ago, and the "failing" drive is still fine.)
Nonetheless, the drive's SMART mechanism recorded that the drive had exceeded its maximum safe temperature theshold once, meaning that even though all other SMART values are "Never Failed", that single one is "Failed". Which in Smart Utility's illogical universe means that my drive is dead, which it's not.
I have another drive that had three bad sectors. It wasn't fun to fix them -- I had to move all 400GB to other places, low-level reformat the drive, then copy everything back -- but the fact that it had three bad sectors (that are now reallocated, i.e. "fixed") means that Smart Utility has given up on the drive.
Note that drives actually have a threshold for how many bad sectors they tolerate, and three is below that, so my drive didn't even fail the bad sector category in the SMART listings.
There's a lot of nuance to this, and while it's helpful to look at what the drive itself thinks are issues, use your brain to interpret what it means. Obviously, you should ALWAYS have backups, and obviously, if you hear clicking and have degragded performance, those are bad signs. For all the rest, keep a level head.
