Snow Leopard: Enable native NTFS read/write support Storage Devices

Snow Leopard(Mac OS X - 10.6.x) has the ability to mount NTFS volumes as read/write, but it's not enabled by default -- just read only is supported, as in 10.5. Here's how to get full read/write support for NTFS drives in Snow Leopard. First, uninstall NTFS-3G or Paragon if you're using either one.

Here's how to get read/write support for NTFS drives in Snow Leopard:

In Terminal, type diskutil info /Volumes/volume_name, where volume_name is the name of the NTFS volume. From the output, copy the Volume UUID value to the clipboard.
Back up /etc/fstab if you have it; it shouldn't be there in a default install.
Type sudo nano /etc/fstab.
In the editor, type UUID=, then paste the UUID number you copied from the clipboard. Type a Space, then type none ntfs rw. The final line should look like this: UUID=123-456-789 none ntfs rw, where 123-456-789 is the UUID you copied in the first step.
Repeat the above steps for any other NTFS drives/partitions you have.
Save the file and quit nano (Control-X, Y, Enter), then restart your system.

After rebooting, NTFS partitions should natively have read and write support. This works with both 32- and 64-bit kernels. Support is quite good and fast, and it even recognizes file attributes such as hidden files.
