Hi guys. Yesterday, I plugged in an external hdd into my computer in order to watch some movies. The first thing that popped up on my screen was a message saying the drive has to be formatted. I can't format the drive because it's not mine and the owner has very very important info on it. I've tried it on another system and it says the same message. Please help me. Is there a way I can salvage the information on it? Or recover it? PLEASE help me. Thank you. P.S. I've used the hdd to watch movies before and it never had a problem.
