richwhite: Yes. Doing this formats your SD card. (The simple tutorial way, at least, but it doesn't get much easier than that.) Just like reformatting your drive, you'd lose whatever's on there. On the other hand, why can't you just copy your stuff from your SD card to your computer, then do this? Just do that, then after putting MeeGo on your SD card, you can make another partition after the MeeGo partitions, and put your files in there.
