I have an old hard drive that I have no use for, and want to have some fun with it at school. I have a PSU, but I'm not 100% sure how to power it without a motherboard. I know that there is a way to make some sort of switch, but I don't know the details. If you could describe it in depth or link a video to it (I'm more of a visual learner), that would be great. Thank you to those of you that help. Also, if it makes any difference, it is a SATA HDD 7200 RPM Hitachi.
