Story has it, this hard drive caught fire. Afterwards, the owner replaced the burnt bit and now the drive still works.
Lucky guy, especially if his hard drive is house to a lot of important files. Since the NSA incident, I have been very reluctant in using cloud services, but one never knows when their physical drives could one day get up and commit suicide. So what the heck? Look on NSA scums, you might not like what you see. ;-]
