I have bought this cable in order to use a separate USB adapter to power my desktop hard disk (3,5")
At one end is a normal USB male connector, and on the other end is an adapted 15-pin plug. These are the connected pins, I believe. Which I think they are correct pinned
Should I connect anything else to turn the hard disk on? Or should this be enough? Am I doing anything wrong?
There are many cables like the one in the image below, but what I want is to manage the data cable be independent from the power cable. Is that possible? I was looking for a cable 7-pin SATA male to USB male but I couldn't find any. I want to connect the disk to a Raspberry and use a different power adapter to make it work.
Any suggestion would be appreciated.
