IT guy checking in.
The only time I've even seen drive temp sensor alarms is on server raid arrays and other similar hard drives/SSDs.... Never in my life have I seen one available on a consumer device, nor have I seen any alarm for and drive temp, go off. Out just doesn't happen.
IMO, this is one of those language barriers where people call their computer chassis (and everything in it) the "hard drive".
Applying that assumption, their updated statement is: His computer over heated.
Idk what kind of shit system he's running on that 60k rows would cause overheating, but ok.
