Just got a Pi2 and I'm trying to write to a micro sd card. My old Pi was one of the first types that used a large sd card. So far I haven't had much luck getting a micro card to format. Before I'd use gparted to erase the card and partition it to ex2. so far I've tried 2 cards and have gotten one that won't create a partition table and another that for whatever reason apparently can't be written to. Both are Sandisk cards I had laying around.
What little searching I've done was from Wikipedia http://en.wikipedia.org/wiki/Secure_Digital
and there are some scary lines about write protection and DRM protection that can't be removed from cards. And then I clobber it with gparted, trying to overwrite the contents so I can install Raspbian. Not sure if this is an issue, I don't see anyone else having a problem, not sure what I'm doing wrong. I'm using a Fedora OS to do all this, if that matters.
