Adding NTFS support to Linux

Usually most of the linux distributions come without NTFS support. For adding NTFS support to linux we use NTFS-3G driver. The NTFS-3G driver is a free and commercially available and supported read/write NTFS driver for unix-type (Linux) operating systems. It provides safe and fast handling of the Windows XP, Windows Server 2003, Windows 2000, Windows Vista, Windows Server 2008 and Windows 7 file systems.
The latest stable version of NTFS-3G can be found at http://www.ntfs-3g.org/

NTFS-3G uses FUSE lib ( Filesystem in Userspace ). FUSE provides set of functions to implement file system in a userspace program.
The latest version of FUSE can be found at http://fuse.sourceforge.net/

Installation:

Download NTFS-3G and FUSE from above links
Untar FUSE
Install fuse with following command

#./configure
# make
# make install

Untar NTFS-3G package then type

#./configure
# make
# make install

If there is no error in the installation, ntfs drive can be mounted in read/write mode
mount the drive with -t ntfs-3g option as follows:

# mount /dev/sda1 -t ntfs-3g /mnt/win
