ok. i have done partition with bootcamp and i like to undo it. however, i just couldn't figure it out. another thing is, when i check my apple HD volume, it says i got 30G free volume. however when i check HD volume just right-clicking on icon, it says i got 20G free. whats up with that? anyone out there who can tell me how to undo my partition and make my apple HD "read out" sane again, please help me. i just switched from window to mac month ago. and i really love my mac. so little step by step guidance will be much appreciated. thanks in advance.
