Issue: How do I mount an NTFS partition from the command line and save this in /etc/fstab to mount during the boot sequence?
Resolution:If running a dual boot system with Red Hat Enterprise Linux and Windows and you are wanting to access the NTFS drive there is a unsupported and highly developmental kernel module which allows a read-only mounting of an NTFS partition. To persue this method you will need to first visit www.linux-ntfs.org/ and download the particular RPM which matches your kernel version. To know which kernel version you are running you can type the following command:
# uname -r 2.4.21-20.EL
After downloading the RPM best suited for your system install the package as follows:
# rpm -ivh kernel-ntfs.rpm
This will configure all necessary items to have the module load correctly on bootup. For now, load the module manually type the following:
# modprobe ntfs
If the module loads successfully you will be able to mount a NTFS partition just like any other filesystem type:
# mount -t ntfs /dev/hdb /mnt/ntfs
Next edit /etc/fstab and append the following line to have your NTFS partition mounted during each boot:
/dev/hdb /mnt/ntfs ntfs defaults 0 0
