Yesterday I had a need to not just read but write as well to an external USB NTFS formated drive. (I only run Photoshop on my Macs.) I found NTFS-3G to work, as usual, quite nicely. If you’re not familiar with it I would suggest heading over to their Q & A section for a few minutes.
“The NTFS-3G driver is a freely and commercially available and supported read/write NTFS driver for Linux, FreeBSD, Mac OS X, NetBSD, Solaris, Haiku, and other operating systems. It provides safe and fast handling of the Windows XP, Windows Server 2003, Windows 2000 and Windows Vista file systems.
NTFS-3G develops, quality tests and supports a trustable, feature rich and high performance solution for hardware platforms and operating systems whose users need to reliably interoperate with NTFS.
The driver is in STABLE status since 2007. It is used by millions of desktop computers, consumer devices for reliable data exchange, and referenced in more than 20 computer books. Please see our test methods and testimonials on the driver quality page. “
