That's exactly what I was looking for. Thank you all

Not exactly, cause when you open the explorer it will start running (or not?)

Hy, I'm looking for a way to add an extra hard drive to my pc. However, it should only start sometimes, because it is not always needed, like a backup. Is there a solution like a switch or a button so I don't have to open the PC every time. I mean something like a SATA adapter that I can activate.
