I keep seeing documents like this saying to use FAT32, but I just don't understand it.
real-life experience has told me many times over that FAT(12/16/32) is a piece of CRAP!
NTFS does not take longer to defrag compared to FAT32 on the same size hard-disc, it takes much less time to defrag compared to FAT32.
as far as FAT32 being faster for disc access, that may be so, but I have to yet to have any problems working with 12+ channels of multitrack audio on a NTFS drive.
