I am new to Raspberry and just got my Pi 2. I got 2 pcs of 32GB Class 10 Sandisk micro-SDs and when I started to use these for NOOBS and OPENELEC, I had problems - both won't boot up; nothing on the screen. I formatted the SDs with SDFormatter and wrote the .img files with the Win32Diskimager - tried a few times. Subsequently I shifted to 3 pcs of 16GB Class 10 Samsung cards, and these work without problems.
After a day of playing around with the 16GB micro-SDs, I was curious and went back to the 32GB cards. I found that some times they work; but most of the time they don't. I searched the net and what I read was that 32GB cards should be OK for the Pi B+. So, my experience with the 32GB is confusing. Anyone having the same issue with the Pi 2?
