I am using from couple of weeks Banana PI M3. From beggining I was using external drive. It was WD device. I have got some issues with this device connected with some read/write operations (I've similiar problems with this device plugged to Raspberry Pi) so I decided to buy new, bigger and better drive - Seagate Expansion 4TB Portable External Hard Drive USB 3.0.
Unfortunately more problems have occured.
When I plugged my new hard drive, M3 stopped boot. When I unplugged hd, M3 started to boot properly.
When I have tried to plug device later, during runtime, there Was no issues, but sometimes after some time of heavy copy & paste operations on hard drive, my banana was turning off completly
Currently I'm using Ubuntu Mate 16.04 and official Banana DC adapter 5V 2A. I have no other usb peripherials.
I've already set max_usb_current=1 in /boot/config.txt
Do you have any suggestions, what can be wrong?
