Somehow I've gone and fouled up my SD card. Everytime I try and install a rom it won't mount the ext partition - yet it seems to be taking up space on my card when I connect it to my computer as if there's a partition there. I installed Velocity 0.4 after wiping my data, cache, and dcache, but somehow it still had all my apps that I had installed before - I'm guessing they installed via apps2sd. Is there a way I can just do a complete wipe of the SD card so that I can hopefully get a good clean install? I've tried using the tool included with Rom Manager but it still has the problem with the ext partition.
