Yup, some devices can be picky about memory cards. I've had SanDisk compact flash cards fail in a Nikon dSLR yet work fine in other cameras. And a Class 10 SanDisk 32GB micro SD card never did work reliably in my Ion Speed Pro video camera, yet does in my tablet and smart phone. Yet a cheap, no-name 16 GB micro SD card works fine in the Ion Speed Pro, while that same type of card is rejected as "too slow" by my phone.
