PiDrive 314GB random beeps

CK_WD,

RPi is connected like above schema with original pidrive cable. You can not connect in different ways. To the point 5 is going 10cm usb cable + power adapter 5V/2A.

Also I tried, that point 4 was unplugged and I added there new 5V adapter, so both devices are powered separately.

Result is as i wrote before, pidrive is random beeping.
