Reclaiming a partition: small issue

It what is almost a double entendre, I do have a small issue.

Amidst all the OSX update that were taking place, and seemingly overnight, I had created some small partitions (30G) to give the OS's a quick run just in case to feel them out (I do this @ work).

had a main 10.9, with another 10.9 which were my 2 main ones (one is for everyday, and the other is for tinkering w/ music)

then I had two smaller ones of 10.10 and 10.11 to test out.

I went to delete the 10.10, and reclaim it. After deleting it, I dragged the window (in disk utility) and hit apply, got that animated bar, and nothing else. The 30G remains unclaimed.

Any quick insights before I escalate this?

Thanks - and cheers.

H!

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.
Happy tinkering!

Gparted will do what you want, as noted by hexdly. A Mac program that will do this is iPartition, but it costs about $50 US to buy.

Test future versions of OS X on an external hard drive, is all I have to say.

There may also be several "Recovery HD" partitions to be dealt with as well.

If you install via Target Disk Mode and before that run Disk Utility & format/ repartition your drive, you"ll be rid of the Recovery partition.

The big deal is: do you really want to get rid of it? This Recovery partition is only 650 MB in size, and can be a real lifesaver. Just my 2 cents...

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.
