OSX NTFS Mount

sudo vifs

will pull /etc/fstab into vi. Add the line:

UUID=9EA62218-DFC0-447D-8E0E-EC8225E1A256 none ntfs rw,auto,nobrowse

Replace the UUID with the Volume UUID of your NTFS drive. This is how you get it:

diskutil info /Volumes/HP\ Portable\ Drive/

This will give you info for "HP Portable Drive"
