Okay! So, my macbook hard drive fried. I have like 5 PC hard drives. I've called the Mac store and was told that I could convert a PC Sata hard drive to put osx on it and use it in my macbook. I've tried ever step by step guide on the net. The partitions, the formating, the journaled. And I haven't been succesful. I realy don't want to go out and buy a anew hard drive, when I have 5 that I'm told could work. Thanks so much guys and girls !
