Disk Utility not letting me partition.

Question

Disk Utility not letting me partition.

I want to create a partition to install Ubuntu on, but all I get is this, and it doesn't let me partition it.

I don't know where the grey box (free space came from). All I can do is make the grey box bigger. Nothing else.

All I can imagin is that I tried installing Ubuntu before (from a CD) and when it asked me where to install it I clicked "Free Space" because it didn't ask me if I wanted to partioon the hard drive.

Just remembered that I encrypted the hard drive. Could that be it as well?

So my two questions are:

- how can I make a partition again?

- how can I remove the "free space" partition?

MacBook Pro, Mac OS X (10.7), 13.3", 2.7 GHz, 500 GB

That definitely has to do with the encryption on the disk. Thats what that message CoreStorage Physical volume is referring to.

Sorry I don;t have a solution, if you google for that CoreStorage message you'll get some ideas. One thing I can tell you make sure you have this disk backed up if you start messing around with this. The chances of messing up is sort of high.

Thanks. I'm decrypting it as I don't really need it encrypted, and was only testing.
