Possibly special hard drive.

I found this hard drive at a IT place that was going out of business in a safe I pulled out of their dumpster. Probably 15+ years ago. It has writing on it, I think it says like, bc then numbers over and over and at the bottom it says "keep safe do not loose", then "safe!!" At the bottom. I thought maybe BC meant bitcoin and the numbers were amounts. But I could never get into it. The hook up is way older than I have any cord to fit. Never seen it before. Don't know if it works or what's on it. It was just a guess im probably wrong, and its just wishful thinking, but it's a gamble if you're willing to take it. I will not take a return if you plug it in and there's nothing on it. Or if it won't work. So buy at your own risk. I found 3 or four more with the same writing in the same safe it. It was locked and I had to hammer drill it open.
