Tried fstab.but still the same it didnt work

i open /etc/fstab with gedit

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
LABEL=/home /home ext3 defaults 1 2
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
LABEL=/tmp /tmp ext3 defaults 1 2
LABEL=/usr /usr ext3 defaults 1 2
LABEL=/var /var ext3 defaults 1 2
/dev/hda9 swap swap defaults 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/sda1 /mnt/thumbdrive vfat user,noauto,umask=0 0 0
/dev/hda5 /mnt/windows/c vfat users,gid=users,umask=000,iocharset=iso8859-1,code=437 0 0

i placed hdb5 which is the /dev/hda5 .... but it doesnt work?

[root@localhost root]# cd /mnt
[root@localhost mnt]# chmod 777 windows
chmod: changing permissions of `windows' (requested: 0777, actual: 0755): Operation not permitted

i tried this few options as well but in vain!

/dev/hda5 /mnt/windows vfat users,gid=users,umask=000,iocharset=iso8859-1,code=437 0 0
