Well as Kahless has asked you he is absolutely right if you are trying to mound your windows partition in the same computer then all you have to do is this
1. Log in as ROOT
2. create a dir => $ mkdir /mnt/vfat
3. Now you have to find out the partion no. your windows files are and you have to use this command
4. $ mount -t vfat /dev/hda1 /mnt/vfat
5. here hda1 denotes C drive and u can find your partion in the harware browser if you are using GNOME.
6. Do not write this command from the /mnt/vfat directory
7. Now you can simply change your directry to /mnt/vfat to view all the files there.
8. And yes you have mount it everytime you log in... just a simple command.
Well if you are looking to mount drives on network running windows or other os then you have to configure and let me tell you i am also looking for that
