MacBook Pro Retina won't read a specific SD Card (32 GB Extreme)

I'm using a MacBook Pro (Retina, 13-inch, Mid 2014) Version 10.10.2 and a 32GB Extrema SD Card. I used the SD Card on my laptop two days ago and it worked fine, the day after it stopped reading it. It can read other SD Cards and that card is readable on other computers but not on my laptop. I already erased everything it contained using Disk Utility on an iMac, restarted my laptop, updated it, shut it down waited and turned it on again, nothing like that seems to work.
