+ Every so often my system will go unresponsive. Usually within 15 min from the previous time.
+ The HDD light will stay on completely for this, although I can't hear it "thinking"
+ The mouse will move, the start menu will open, but opening a folder or app will just produce the spinning circle thing.
-- I'm guessing anything that it cached in RAM is responding, but it can not access the hard drive.
+ After a few min, the hard drive light will flash, the disk drive will audibly "think" again, and the system jumps back into action.
What I've tried:
+ SMART monitoring says the drive is healthy
+ full system error check on bootup with WIN7 didn't find any problems (although it seemed to take longer than it should.)
+ Quick Virus scan = clean
I don't hear any warning signs of hdd failure. No error messages.
I figured it out: the case fan died that cooled my harddrives. I don't know why SMART didnt catch the overheating but since I've taken the side off my case, the drive has been fine.
I have 3 of them going in there, and without airflow they baked a bit.
One more reason to go SSD I suppose...
