max usb current pi

I'm using max2play on my pi 2 b, and have had problems with the pi staying available on the network. I've put this possibly down to a power issue and have been trying to set maxusbpower to give my portable hdd some more jiuce. I've set the maxusbpower setting on the max2play web interface but the checkbox doesn't stay checked so not sure if it is set or not? Any other way I can check through ssh?

Cheers
Tony
