Hello, newb here asking a newb question,
I just purchased an external HDD, which has 2 USB ports (for "charging your devices"). I plug the Pi power cable into one of these ports, and the Pi turns on and runs great.
But then if I connect the HDD data cable to the USB port on the Pi, the Pi shuts right off. It won't turn on again until I unplug the data USB.
Has anyone been tried to make this work? Is there any risk to running off the HDD power?
Thanks for any assist!
