windows recognition probs

[squareyes]

Hi all, 
have just installed Ubuntu, had a run around with 
install formatting partitions previously used by
Mandrake 10, but made it.
I have modified fstab 

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hda5       /               ext2    defaults,errors=remount-ro 0
1
/dev/hda6       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   udf,iso9660 ro,user,noauto  0       0
/dev/hdd        /media/cdrom1   udf,iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
/dev/hda1       /mnt/windows    vfat    unmask=000      0       0

but will not show any files in /mnt/windows.
Nautilus shows the folder but no files/folders.
Do I need to set any permissions to access them?
Have ppp setup and running with pon , but is there
any way I can tell how long I have been connected with Gnome?
Have a dial up connection with limited hours.

Am very new to command line, have muddled through this far
having been unable to get Deb to work. Have printed out 
Unofficial Guide.
I would be very grateful for any help in what I am 
not doing correctly.
Thanks in advance,
Take Care
Winton
