This question already has an answer here:
Are the red ports below eSATAp that can power a 3.5'' HDD?
I saw this post about 12V eSATAp and I would guess that they are. However I have a cable like this:
which claims to support 3.5'' drives on 12V, but the disk does not even start spinning. I'm trying to understand if the cable is faulty or the port is not the one I think it is (the disk works fine, by the way).
