Handle NTFS partitions in GNU/Linux

To handle NTFS partitions in GNU/Linux you should install the package ntfs-3g

Note: From April 2011 the ntfs-3g and ntfsprogs projects joined forces so now everything is in a single suite: ntfs-3g.

Most likely your distribution may already have installed the suite ntfs-3g else you can do it by exec

Debian/Ubuntu

$ sudo apt-get install ntfs-3g

CentOS/Fedora/RHEL

# yum install ntfs-3g
