Change the entry in your /etc/fstab to be this:
Code:
/dev/hda1 /media/windows ntfs nls=utf8,umask=0222 0 0
Once you have that fstab entry, you shouldn't have to manually mount it. It'll just be ready in the /media/windows folder when you boot up.
Oh, and make sure you actually create a folder in media called windows.
