SD card corruption: power limits?

I’ve got a veritable punnet of Raspberry Pi’s and been a user since the first release, so I’m well aware of the risks of SD corruption: fortunately it’s rarely happened. However, since owning the Picade I’m having enormous problems with corrupted cards which fail to boot. I’ve tried different brands and I do always exercise good shutdown hygeine.

I am starting to wonder if there is a power issue. I have a RPi2 fitted into the Picade along with the black, slightly higher capacity official Raspberry PSU. Volume is set mid-way.

Anyone else having similar problems?
