I took my old 320GB SATAII Internal hard drive out of my old Windows XP PC, bought a NexStar CX enclosure to make it an external HD plugged it in and it didn't work on my MBP. So, I assumed it was a formatting issue, The HD is formatted to NTFS. I attmepted to completely format the disc but XP wouldn't let me saying (paraphrased) "you can't do this because it will make your computer not work." So I partitioned it and made the partition Fat32 because mac's can read/write this format (yes?), but it still doesn't recognize the HD at all. How can I get this to work? How do I format the HD from my PC (because the PC is the only thing that recognizes it) for mac? I'm not sure if I've provided enough information for you so questions are welcome.
