Please post the contents of /etc/fstab file.

Give some more information as said by harken, we cannot read your mind.
Wich internet connection do you have, modem, ADSL?
If you have ADSL or some kind of broadband connection there is lots of other threads that WILL help you.
Just use the "search" tool on this homepage.

Does Red Hat 9 include support for NTFS? (I use Fedora, which doesn't.) If not, you'll need to install the NTFS drivers.

In any case, you need to mount the NTFS file system to some mount point (which you need to create) before you can browse the files.

That was the point of the criptic "post contents of /etc/fstab" entry. /etc/fstab is where the mapping between the physical devices (e.g. /dev/hda1) and the file system (e.g., /mnt/ntfs/c) would be defined.

All this is explained fairly clearly the the "How-to" section of the NTFS project at http://linux-ntfs.sourceforge.net/index.html

Hope this helps
