Yeah I have been encountering this recently, wonder if thats what fubared my new hard drive... only had it 4 days when installed 3.13 with NVIDIA IDE driver and drive started to fail. This is a bit of a joke to be honest NVIDIA should be testing their drivers before public gets them so it dont fubar the drives, had alot of weird hdd detection problems then eventually it hard locked on every boot. Stuck a new HDD in rolled back to default XP MS driver and seem's fine thank god. Also noticed with NVIDIA IDE driver in the event viewer CD ROMS were whining about bad blocks even though there was no disc's loaded! Sometimes the same with the hard drive, NVIDIA IDE drivers do seem dodgy.
