When it comes to full read and write support for windows drives, OS X can only do so on FAT32-formatted partitions. The newer and popular NTFS format is a more stable option for Bootcamp and other applications; however, it is only readable by OS X. One of Apple's selling points for OS X is the enhanced Windows compatibility, but the lack of write ability to NTFS drives makes transferring files between the Mac OS and Bootcamp rather cumbersome. Luckily, third-party utilities enable this missing feature.
