1. With DU, you cannot resize the uppermost partition in the graphical partition window. All the ones beneath that, you can.
2. If you really want to juggle partitions around, and are not afraid of Linux, I can strongly recommend running the Gparted Live distro.
That is a lightweight live linux with a very powerful partitioning tool as its sole purpose. I've put it on a USB disk for myself, but have not actually had the need to use it.
Mind you: there are 2 versions: a 32 and a 64 bit version. Choose the right one for your Mac.
And: backup, back up and back up before you try it.
Thx for the insights. Not a huge deal, outside of the fact that it just bothered me to have a missing 30G. The best part is that this is a near back up laptop. I had 80GB> of stuff to back up. Mostly apps, not tons of data.
Was given a few options: some via terminal, some 3rd party options like listed here (thanks to all). But was also told that a simple route would be to back up and re install. which I might do. I want to reduce this to 2 partitions. Anyhow, Thanks for all the suggestions. Was never mega versed in working w/ partitions. great lesson.
