This is a difficult issue for some new Mac OSX users. They have their external HD drives, formatted in NTFS, and when they plug it into their mac, they find they don’t have write access to the drive. You can easily solve this without having to install third party software. (at your own risk)

1. Open a terminal, and type this
diskutil info /Volumes/**THE NAME OF YOUR DRIVE**
where you change **THE NAME OF YOUR DRIVE** to the actual name of your HD drive (or usb stick…)

2. You will get a whole list of info on that drive. Look for “Volume UUID”, and copy the corresponding value.

3. backup the file /etc/fstab if it exists on your system by typing
sudo cp /etc/fstab /etc/fstab.backup

4. edit the fstab file with ‘nano’
sudo nano /etc/fstab

5. insert UUID= and then the value you copied from step 2. after that press space, and type none ntfs rw you must see something like this:
UUID=123-456-789 none ntfs rw

6. save, exit nano, reboot system.
ctrl+o (=save)
ctrl+x (=quit nano)

now check if it works… and it will
that’s it!
