I bought 3 tb segate internal harddrive and then bought startech enclosure for it. when i plug the hard drive into my macbook pro(2009) running 10.8.2 and it does not recognize it. Then i booted my laptop with windows 7 and it recognizes the harddrive, i installed macdrive on windows and partitioned it as HFS+ but it still doesn't recognize it. Then i plugged in my friends 320gb wd external harddrive wich is partitioned as FAT32 and it works on his MBP 2009, but it wont recognize on my when i am running 10.8.2. It would work when i run windows 7 but not when i run 10.8.2. I dont see what the problem is. Also when i plug in regular jump drive it easily recognizes it, can some one please help me out.
