I didn't look for it, but I very much doubt it and would strongly discourage you from trying it if you are somewhat interested in your files' integrity. At least, it's not possible using the GUI maybe it can be done using diskutil in the Terminal. If you want an NTFS disk, you have to do the formatting on a Windows machine. It is not possible, not even in 10.4.1, to create an NTFS partition or disk.So the user experience is now like with formatting in any other format.
MAC FORMAT NTFS PARTITION MANUAL
I can't remember for sure (although I did it just a few minutes ago), but I think you don't need to do manual unmounting in 10.4.1 any more Disk Utility will do it for you. This hint mentions it is possible with Disk Utiliy, but only after initial unmounting.



MAC FORMAT NTFS PARTITION MAC OS X
This has saved me a lot of trouble: It is now possible to reliably read NTFS disks (NT File System, as used by modern Windows versions such as 2000 or XP) under Mac OS X 10.4 (tested under 10.4.1).
