Snow Leopard 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:

  1. 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.
  2. Back up /etc/fstab if you have it; it shouldn’t be there in a default install.
  3. Type sudo nano /etc/fstab.
  4. 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.
  5. Repeat the above steps for any other NTFS drives/partitions you have.
  6. 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.
