Enterprise SMART firmware on home drives?
On one occasion, a SMART launched me a warning that the drive had worked "too many hours" on 160GB home drive.
There wasn't a single fault with it, even after I donated it charity, when I duly formatted it and slapped Ubuntu on it, just to deliver a working "ran when parked" machine.
On a home drive, it was a pure trolling warning. The drive didn't have a single "Enterprise MTBF" goal, put apparently, the SMART crapped all over itself because the machine ran 24/7 for over 10 years. In fact, said warning only showed up if you ran a SMART diagnostic, but it never borked on boot over that.
