Hey guys, I was on an unstable version of MIUI a month or so back and I ended up borking two of my sd cards. I got a new one but I picked up a transformer on black friday and I'd rather not buy another sd card if I can help it. They won't format on my computer or phone, I tried everything from formatting using cmd prompt to low level format tools. Any ideas?? I feel like there has to be a way to fix them since they were working perfectly fine before the rom.
