After lots of studying and thinking I have finally had the drives
mounted automatically when I boot Ubuntu, and made it accessible for
other users.
I did this:
Below is the fstab file of my system including the bottom two lines added by me:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda6
UUID=1f66d389-9ee8-47d8-8ee6-9c384ee1c700 /               ext3
relatime,errors=remount-ro 0       1
# /dev/sda7
UUID=5ec0269f-6867-4350-ab8c-e1d9ed7a03d6 none            swap    sw
           0       0
/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
# /dev/sda1
UUID=6488EB4A88EB18F6  /media/c  ntfs-3g
rw,auto,users,uid=1000,gid=100,umask=000,dmask=000,fmask=111,utf8  0
0
# /dev/sda5
UUID=28A7-268E  /media/d  vfat
rw,auto,users,uid=1000,gid=100,umask=000,dmask=000,fmask=111,utf8  0
0

Now it can mount automatically and be accessible by other users. But I
can't change permissions of folders/files inside the drives even the
folders/files inside my home directory. I used:
sudo chmod
But did not work. What do I do?
