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 Don't forget to defrag the filesystem first! If you were making it larger then it wouldn't matter, but if you are shrinking it, then you want your files to be contiguous and not sprayed all over the partition. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I did not find a resizefat32 or similiar. You need fatresize, which doesn't appear to be in portage. The approach when reducing a partition's size is to first reduce the size of the filesystem, to slightly less than the final partition size for safety. Then delete and recreate the partition, with the same starting point. Finally resize the filesystem to fill the new partition. What tools do I need? The easiest way is probably to use GParted, which does all the hard work for you, just tell it the new size of the partition. It will also create the second partition for you, as a bonus. (beside the way to backup the SDcard, reinitialize it, put 2 partitions on it and copy back the stuff.) Given that you should backup any important data before resizing any filesystem, this may be the easiest method. -- Neil Bothwick Unsolicited advice is the junk mail of life pgpCI2nxoDgmv.pgp Description: OpenPGP digital signature
