This is totally different than NTFS, so put all ideas of using mount_ntfs out of your mind since it won't help. The FAT32 support in FreeBSD currently doesn't support "large" disks. I don't know the specific value of "large", but there is some comments in the code that point at certain calculations that break for "large" disks. -- Matt Emmerton
