I had 2 partition in my Mac : Macintosh HD and Back-up. I wanted to erase the Back-up partition to increase Macintosh HD's capacity. I had no problems to erase the Back-up partition but resizing the Macintosh HD is lasting much more then I expected... It has been around 30 minutes and says : Preparing to partition disk. I did partitioning and resizing lots of times before but lasted only a few minutes. What should I do?

If the hard drive light is active, wait !! (I'm not a mac person, but I'm positing that there is a lot of information which needs to be moved arround, and copying is a very slow process) –  davidgo Apr 29 '13 at 8:52
    
There is no hard drive light on Macs! –  moray95 Apr 29 '13 at 8:56
    
Leave it this way for a couple of hours. If it's still at "preparing", you could abort it, give your Mac a restart and try again. Also, make sure you stopped the Time Machine so it's not trying to backup any changes to that partition you want to delete. –  Radoo Apr 29 '13 at 9:01
    
Actually the delete part is done, no problems there, Time Machine is off. It's just the resizing process of the main partition. –  moray95 Apr 29 '13 at 9:03
    
Patience, then! :) –  Radoo Apr 29 '13 at 9:22
