It could be that ntfs-3g has been damaged. That can be checked with
the command
rpm -V ntfs-3g
which should return nothing. If it does return something, re-install
ntfs-3g.
Another possibility is that the disk has been corrupted. To check
that possibility, first verify that you have the smartmontools rpm
installed (do `rpm -q smartmontools`) and then do a short offline test of
sdh, the drive which has the NTFS filesystem:
smartctl -t short /dev/sdh
After the test has been given enough time to complete, do
smartctl -a /dev/sdh
The output should end with the result of the short offline test, and
before that result the output should list recent errors detected. The
status of the test should be "Completed without error" and there should be
no errors detected. Even better, but much more time consuming, is
smartctl -t long /dev/sdh
For more information on smartctl, do 'man smartctl'.
If the disk drive is ok, and the NTFS filesystem contains some
uncorrupted version of a Windows operating system, you might be able to
boot your computer into it. In your case, when you installed SL6 perhaps
you also retained the ability to boot into Windows, and there are already
the appropriate lines in /etc/grub.conf. If they aren't already in
grub.conf, adding to its end the following lines may allow you to boot
into whatever operating system is in /dev/sdh1:
title Testing Booting into my NTFS filesystem
rootnoverify (hd7,0)
chainloader +1
The "7" in hd7 is there because 7+1=8 and the "h" of /dev/sdh1 is the 8th
letter of the alphabet. The "0" in hd7,0 is there because 0+1=1, as in
sdh1. After /etc/grub.conf has the required entries for booting into
/dev/sda1, reboot and select from your grub choices the operating system
corresponding to the NTFS filesystem. If booting into /dev/sdh1 fails,
either my instructions are wrong, the NTFS filesystem wasn't one into
which one may boot, or the filesystem was corrupted. If it works, then
the filesystem is probably ok, though if you know enough about the
operating system into which you've booted, you could try one of its disk
checking or repair programs.

Hmmm let's do it one more time (could you please give the output you get
from each command if any):
1) unmount the sdh drive (in case of)
# umount /dev/sdh1
Maybe you could rather unmount everything by:
# umount -a
Later you can remount everything using:
# mount -a
2) create a new mount directory
# mkdir /mnt/mymountdir
3) list the drives
# fdisl -l
I get this:
Device Boot Start End Blocks Id System
/dev/sdb1 1 121601 976760001 7 HPFS/NTFS
4) mount your ntfs drive to the directory
# mount -t ntfs-3g /dev/sdb1 /mnt/mymountdir
5) list files
# ls /mnt/mymountdir

Ghis,
Thank you for your reply. I tried, nothing echo, but when I check with
"df -Th", the disk has not been mounted:(
Do you have any other suggestion?
Best!

What about:
mkdir /mnt/mounted_disk
mount -t ntfs-3g /dev/sdh /mnt/mounted_disk
This is the basic mounting command for ntfs partitions, more infos on
mounting options here:

Hi,
I want to mount a NTFS hard disk. I have installed the ntfs-3g, but
there is a "Segmentation fault" information come out. I don't know how to
fix it. I am a freshman of Linux. Would anyone tell me how to mount this
NTFS hard disk? Much appreciate!
