Just to add to what TankerKevo has stated, you first need determine where your NTFS partition is, then you need to decide where to attach it, then you need to mount it. To view your disks, run this command as root
That will display the hard drives and partition information. Make a note of NTFS partition. As TankerKevo explained, if will be something like /dev/hda2 or /dev/hdd1, etc, depending on where it has been installed and what other partitions co-exist on the hard drive.
Next you want to make it accessible to your system. If you don't already have a mountpoint created for it, you will need to create one, perhaps something such as /mnt/ntfs.
Finally you will want to mount it, exactly as TankerKevo stated, but you need to make sure that the device identifier and partiition number correspond to your exact NTFS partition.
Code:
mount -t ntfs /dev/hdxy /mnt/ntfs
where x is the device identifier and y is the partition number.
Just for future reference:
/dev/hda = primary master
/dev/hdb = primary slave
/dev/hdc = secondary master
/dev/hdd = secondary slave
That ought to do it. Good luck with it -- J.W.
