If you need to access your Windows NTFS partition to your CentOS and/or Fedora machine you can do so by following these steps. The software library you will need is called ntfs-3g. This how to assumes your NTFS drive is physically attached to your CentOS/Fedora box.
On your Linux box:
1) Create a directory where you will mount your NTFS partition. This directory can be in any location and it have whatever name you want.
2) As root run the fdisk -l command in order to see under which directory your Linux box sees your NTFS drive.
Here is an output example. You are interested in the first line
Disk /dev/sdb: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x665e665e
3) Mount your NTFS drive to the directory you previously created.
mount -t ntfs /dev/sdb1 /mnt/ntfs
The mount command may complain about not finding the drive. In that case just add or remove the number 1 from sdb.
