My hard drive is a 3.0 1TB seagate with Wi-Fi (NTFS). It needs 5V and 2A.
My device is Raspberry Pi 2 B running Raspbian.
I created a Y-Split USB 3.0 cable. One end is going to the Drive (obviously) There is one end going to a wall charger (the one that came with the hard drive) ---> ONLY THE GROUND AND POSITIVE WIRES ARE ATTACHED.
The other end goes to the RPi where the Ground and Positive wires are completely disconnected since I am getting power from somewhere else.(But the data wires are all still connected.
I tested it on my Windows desktop and my Windows laptop and the drive works perfectly fine.
nstf-3g installed on the pi.
The drive has always been used with windows machines previously.
When I type
sudo blkid, the drive does not show up.
I tried googling for this issue for a while now.. Every forum says it is because the Hard drive is not getting enough power and to connect the drive to a USB hub. But my drive is getting full power from the wall outlet.
I'm starting to wonder if the problem could be: since the positive and ground wires were completely disconnected from the USB cable's end going to the Pi, the Pi somehow does not know there is a drive connected there? I find it weird that it works on my windows machines then?...
If you need anymore information let me know.
