Tried both OSMC and OpenElec.
On OpenElect when connecting HDD, the system restarts and hungs during boot

Note that the external power supply usually only provides the 12V for the motor.
The 5V for digital logic probably comes from the Pi and may be more than it can provide.

Might be worth trying connected through a powered usb hub.

is typically an insufficient power issue.
