I just purchased a 400 GB WD mypassport essential. I have windows vista on my PC, when I check the format of the drive on vista, it says its on the default, NTFS. For some reason, however, I cant transfer my 1080p quality movies that are over 4gb into it...(a problem that should only occur in FAT32 format.?) I can format the harddrive to exFAT, but I am dont know if itll work with my mac..? I have paragon on my macbook pro so NTFS works. But yea, my question is just if exFAT will work on my mac laptop. Or if there is any way i can get the NTFS format to take files larger than 4gb.
