vfat not mounted at boot

I just did an hd-install in beginner mode, everythings working except that I 
need to manually mount my /mnt/hdc5 everytime I reboot, here is 
my /etc/fstab:

# /etc/fstab: filesystem table.
#
# filesystem  mountpoint  type  options  dump  pass
/dev/hda1  /  ext3  defaults,errors=remount-ro  0  1
#this is the part that doesn't get mounted automatically 
/dev/hdc5 /mnt/hdc5  vfat iocharset=iso8859-15,umask=0,codepage=850  0 0

proc  /proc  proc  defaults  0  0
/dev/fd0  /floppy  vfat  defaults,user,noauto,showexec,umask=022  0  0
usbdevfs  /proc/bus/usb  usbdevfs  defaults  0  0
sysfs  /sys  sysfs  defaults  0  0
/dev/cdrom /cdrom  iso9660  defaults,ro,user,noexec,noauto  0  0
/dev/dvd /dvd  iso9660  defaults,ro,user,noexec,noauto  0  0
/dev/cdaudio /cdaudio  iso9660  defaults,ro,user,noexec,noauto  0  0
