Probs not your hdd, you can use crystaldiskinfo to see if you have dead drives, but I dont think it would work at all if they were. Strange, have you thought about getting an ssd and then a 1tb normal drive?

EDIT: Maybe even upgrade to win 10, I think you can still upgrade for free, its just not avertised
