I have several external drives and only use them to back up files on a monthly basis. Is there an easy way to disconnect them from spinning up each time I turn the computer on. In the past, I have disconnected the USB cable from the computer thinking this would prevent them from “turning on”. Not sure if that is the correct thing to do. The top of the units are slightly warm indicating that power is being consumed even when computer is off. This may just be heat from the internal power supply and not necessarily the drive spinning.
I realize that once I use them, I could secure the computer and remove both the power and USB cables.
Any (easy) suggestions.
