exFAT

There are no such drivers. OS X can read FAT and NTFS only. You may need to copy what's on the drive to another drive formatted so it can be used on the Mac. Or you can install Windows 7 on the Mac.

Windows on Intel Macs

There are presently several alternatives for running Windows on Intel Macs.

1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak 2 or Vista. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.

2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.

3. VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.

4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.

5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.

6. Last is Q. Q is a freeware emulator that is compatible with Intel Macs. It is much slower than the virtualization software, Parallels and VM Fusion.

Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.

See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.

Boot Camp is only available with Leopard or Snow Leopard. The Boot Camp Beta that was used with Tiger has expired and is no longer available for use. So contrary to the other poster's comment, Boot Camp isn't truly "free." You must purchase Leopard or Snow Leopard to get it.

Why put the complete blame on Microsoft?
Apple needs to take the blame as well. Yes, Microsoft licenses the specification, but apple could get the license and providevthe exfat driver. Right now you think it is a hard drive issue, but it will soon become a camera issue. The SD card association has adopted exFAT exclusively for the SDXC memory card, and although very expensive right mow, give it 18 months and those cards will be everywhere. If you are going to want to shoot HD video on 64 GB or larger memory cards and work on those videos on the Mac, someone is going to need to come up with those drivers sooner or later.

The newest Macs ship with an exFAT driver included. This driver will probably also be part of the upcoming OS X 10.6.5 update.

OS X 10.6.5 has exFAT support.
