[QUOTE="rbpeirce, post: 1948668, member: 410088"] I looked thru the Disk Utility User Guide and I guess my big problem is how do you know which is the first and last partition? For example, to enlarge a volume you must delete the volume that comes after it but you can't enlarge the last volume. [Volume, in this case, seems to mean partition, not volume in a container.] How is that defined? There is a tiny little partition at the top. Call that the first partition? Do we go clockwise or anti-clockwise from there? My guess is clockwise but I'm not sure. Here's where it gets tricky. I don't want to try this until I've backed up the drive, but I can split the large partition into two pieces and the new piece falls between the Time Machine partition and the occupied part of the split partition. So far so good. Now, if I want to enlarge the Time Machine partition I need to delete the partition I just added and adjust the size of the Time Machine partition to fill that space. If it is "the last" partition I won't be able to do that. If it isn't I may. However, if I delete that partition wouldn't one of the other partitions automatically fill that space? I can wait until I have more drives to play with but maybe somebody knows. [/QUOTE]
