I have a 1T Western Digital external hard drive. I'm using it mainly to store movies. When I try to format to NTFS, I get an error message that says 'Windows was unable to complete format'. However, it will format to exFAT without any problems. Is there a any real reason why I should not just go with the exFAT system?

ETA: I'm running Vista.

exFAT does require at the very least an up to date version of Windows XP, so it's slightly less interoperable than NTFS. Also, if you're going to use with a Mac, that will require Snow Leopard and Linux has yet to have usable support.
