Not mine, his:
So I powered the system off and pulled the drive, I examined it and it looked fine, so I figured I would just plug it in while it was out of the case to make sure it was running... when I hit the power button flames..LITERALLY shot out of the bottom of the HDDOuch. I had a CD explode inside the drive once. It knocked the door off of the front of the tray, and embedded shards of plastic inside the case lining. It was loud and dramatic, but not nearly as dramatic as fire.
...End of story.
