You will probably want to backup /etc/fstab beforehand.
Here's an example of a ntfs entry:
Code:
/dev/hda2 /mnt/ntfs ntfs users 0 0
It mounts the second partition of the master hard drive at /mnt/ntfs and should allow anybody to mount it.
If you have Fedora CD1 keep it handy. Boot from it and run
and you should get a text environment to recover.
If you feel brave see the man page for mount with the
command.
