Clay: It wasn't so much the "This is a BETA" as much as the "use at your own risk, we assume no responsibility for anything that may happen".

dattani98: Most likely there's a swap partition on your RSMMC card, I've had varying degrees of success with Windows being able to see non FAT/NTFS partitions. Best bet is to get a linux boot CD/disk, run fdisk, and remove all partition data. If you're stuck in Windows, partition magic or the like should do it. www.tucows.com should have a load of free software to destroy partition tables with.
