Nico, There's not an easy way that I'm aware of. You can use Panther's Disk Utility to back up your partitions to another drive by making disk images of them (make compressed versions as you're low on space). Then reformat your drive the way you want using the Disk Utility in the Panther install cd (you must boot up from the cd - it's in one of the drop down menus). You can then restore the backup images to your new partitions. Expand (not restore) the disk image of "B", select it's contents, and add it to your new "A" partition. If you're out of space and don't have an external drive, maybe you can backup a partition or two to DVDs and expand or restore those using the Disk Utililty of a working OS on your newly formatted drive. Hoping it's not as confusing for you to read as it was for me to write! Rick > My G5's hard drive has 5 partitions.
