    Tell us what you are trying to accomplish. NTFS is a Windows format. OSx does not work with NTFS.

    OS X can only read from an NTFS file system. It cannot write to it or format a partition with it without buying a 3rd party solution. Why do you want an NTFS formatted partition? I assume this is all for an external drive?

    Either format the drive (I'm also assuming this is an external drive) on a Windows machine, or get a third-party NTFS Driver.


    There are a number of iffy open-source ones out there, and two commercial for-pay drivers:


    Tuxera NTFS, and

    Paragon NTFS


    Both products seem fairly well regarded (I use Tuxera personally, but it has nothing to do with any opinion I have about the relative quality of the two drivers; I simply happened to be using a free product from Tuxera when I needed to ugrade to get some additional features).  If there are any differentiators between the two, they are probably:  Tuxera is focused entirely on NTFS, and some of their developers are major contributors to the OSXFuse project which replaced MacFUSE; and, Paragon also makes an ExtFS driver (Ext is a family of common Linux filesystems) and has a bundle offer for the two drivers bought together.


    If you go the commercial driver route, you should of course research the two yourself and make your own decision - based on your own requirements, budget, and so on.

    Ah, 40GB. As you found out, FAT32 is limited to files 4GB or less in size. You could format in exFat which can easily take a 40GB file and is supported in OS X from 10.6.5 and many versions of Windows.

    Uh-oh, just saw you signature line, you are running 10.5.7 so exFat is a no an option for you. As g_wolfman said you could try 3rd party solutions.
