Snow Leopard has the ability to mount NTFS volumes as read/write, but it’s not enabled by default.
Here’s how to get full 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 vi /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. (Thanks go to Chrysaor, who discovered this).
