Before you peek into this topic to say "OS X can only read NTFS, not write to it", save the effort; I already know that. I have a 1TB WD MyBook Studio. I partitioned this drive into 2 parts, an Mac OS Extended partition and, using Win 7, an NTFS partition. Now my MBP can mount and see its partition just fine, but it refuses to mount the other NTFS partition, seeing it in Disk Utility as MS-DOS (Fat) format with a weird name. How do I get the MBP to mount the NTFS partition?
