I have a 500 gig hard drive which I dual boot with Scientific Linux and Windows. I wanted to access the Windows partition from SL and this is what worked. I ran the following command and while it worked, there was a message that something-or-other either did not exist or was already installed – I actually cannot recall. But, again, this worked fine:

yum install fuse fuse-ntfs-3g dkms dkms-fuse

Next, edit /etc/fstab as follows. To mount read-only:

/dev/hda1 /mounting/win ntfs-3g ro,umask=0222,defaults 0 0
/dev/hdb1 /mounting/win1 ntfs-3g ro,umask=0222,defaults 0 0

To mount read-write:

/dev/hda1 /mounting/win ntfs-3g rw,umask=0000,defaults 0 0
/dev/hdb1 /mounting/win1 ntfs-3g rw,umask=0000,defaults 0 0

I added this to /etc/fstab:
/dev/sda1 /windows ntfs-3g rw,umask=0000,defaults 0 0
