Hello muhackl,

You were right.

Now I was testing both. Here are my results. The problem is still a to low energy.

First test: Raspberry Pi 2 and HifiBerry AMP+ (with edimax wifi dongle, 2.5″ hard drive and the hifiberry amp+ power supply). My hard drive is hanging/klicking like you said.

The problem was a to low energy. For this you have to change the Raspberry Settings and set a tick under max USB current (Increases the intensity of current on USB-Ports. If enabled, the USB-Ports get 1.2A instead of only 0.6A.) – now my hard drive run without hanging.

Second test: Raspberry Pi 2 and HifiBerry AMP + (with edimax wifi dongle; 7″ touch screen and only with the hifiberry amp+ power supply)

Now my hard drive having the same issue. I restart my system but first I plug in an additional 2,5A power supply into the raspberry pi. Now the hard drive is running without a issue.

So please try these two things: activate the “max. usb current” in Raspberry Settings and plug in a additional power supply. I hope it is a help for you to solve the problem.

Best Regards.
