SD card corruption

I had miui on my phone and now my SD card is corrupt. Got a new SD card and loaded miui again, and within 10 hours my SD card is corrupt. Can I fix this. Can my phone run miui?

Edit: I formatted my old sd card, but it still won't work in my phone. My phone keeps saying blank external card and asks to reformat it. When I reformat it nothing happens, and the same message pops back up. How do I get my SD card to work now?

I took my wife's and my SD card out and made a backup on the labtop today because of people saying sds were crashing. Had an adapter for it, when I went to put hers back in, it kept saying it was bad, so I formatted it then put back in labtop and put things back on it and now its working fine back in the phone. Mine never acted up at all.

MIUI IS THE BOMB
