Ok I have been playing around with the OS on the mmc but now I no longer want to do that. So questions is how to do I get my card back to the way it was? Do I just sfdisk it?
Wait a mo - if I read your first post correctly, you're booting off the MMC, right? In which case you will not be able to format it from File Manager. You basically want to start from scratch with a fresh flash to the internal memory (not MMC) - am I understanding that correctly? I don't think there's an easy way to reverse the offloading of the boot partition to a MMC card.
So you're using a new 8Gb SDHC card? May I ask what brand? I'm really tempted to get one but it represents a not inconsiderable investment and the stories regarding failures leave me a little hesitant. Just for compatibility info , I have a N800 with the latest OS, booting from a internal 2Gb card.
hehe - sorry jrock, my comment and question was to iball
As long as you have nothing on your card or N800 that you want to keep, my advice would be to reflash the device with the latest OS. In that way, you can start from scratch and put the MMC booting behind you
