I am using the native NTFS read/write support via the /etc/fstab "hack" for lack of a better term. Since I routinely transfer files bigger than 4GB on a jumpdrive between Windows 7 and OSX I don't really have a choice but to use NTFS. I would rather use this than MacFuse/ntfs-3g since I think it is faster. When I write something to the drive and take it to the Windows 7 machine, the security on the newly written file is set to admin - I have to log in as the admin on the Win7 machine, right click and change the security settings. When I formatted the drive initially (on the Win7 machine), I set it for full control for everyone. Is there a way to force OSX to write the file with the same permissions as the drive?
