OS X is able to read NTFS-formatted hard drives, but it disables writing by default. It is possible to enable read+write on NTFS hard drives on OS X using third-party software or by enabling each volume in the fstab as below.
sudo nano /etc/fstab
The following line should be added (where NAME corresponds to your volume name):
LABEL=NAME none ntfs rw,auto,nobrowse
The drive is not listed in the list of volumes in Finder anymore. Instead we need to browse to it via the Terminall.app.
To eject the drive we can use diskutil. Note that the device id may be different.
