I've got a Samsung G3 external, and it looks like I can use it horizontally or vertically ...but it only has rubber feet for vertical standing. ...that means I don't know how to use it horizontally "label up" instead of "label down" (...which I'm told is very important when it comes to drive longevity, because of how heat dissipates).

I'm really not a techy person, so does anyone know if I can figure out which is the right way up without pulling apart the enclosure?

one guess I had was that the power socket is on the right side of a drive that is facing label-up, so maybe that's the way I should sit it. ...but there is a label with a serial number on the 'bottom' (when vertical), and that would be upside down if the power plugged in at the 'left' (when horizontal).
