You probably want the NTFS drive to be mounted and accessible everytime you log in your system. If so, create a folder where you would like to mount the NTFS drive, for example /NTFS. Find the corresponding partition (/dev/hd**) Open then the /etc/fstab file with your favorite text editor and add a line similar to the following:
/dev/hd** /NTFS ntfs auto,user,ro,umask=1000 1 0
Remember to replace the two asterisks with the appropriate letter of device and number of partition ("fdisk -l" will show what is where) and use the directory you just created, if not /NTFS.
