I was wondering if anyone could shed some light onto the peculiar behaviour of my 16gb Sandisk extreme pro.
It if giving me an Error message in my 5d MKIII and telling me to format it but then it won't allow me.
I initially thought the worst but all my pins are fine and I have tried 6 other CF cards on my MK3 and all of them work fine.
The Sandisk card however works perfectly fine in my MK2 as well as my friends MK2 so it just doesn't like the mk3!
I'm going to return the card back to Amazon but if anyone could give me any info on my problem that would be amazing.
