Hi Meino, The "difficulty" with shrinking partitions is that you need to shrink the filesystem in the partition first and then change the partition information (which you can then do if you're careful with your favorite partition tool.) There are definitely tools to do this and I'm surprised parted says it doesn't touch the filesystem in the partition (but that might have been a recent parted change?) Personally, since you're going to play around with the partitions and resizing existing filesystems, you should really have a backup. If you're going to have a backup then the easiest thing to me is to create new partitions and then filesystems and then restore from the backup. However, if you really want to live dangerously, the last gparted boot disc image I used could shrink FAT32 filesystems and partitions. You might want to see if it still can do so. Good luck! Todd
