Can you check the contents of /etc/fstab file ?
As its a very important file, backup it first.
sudo cp /etc/fstab /etc/fstab.bak
Instead of doing it on command line, do it using GUI tools please check this

Note: Its a very important file. Please double check before doing any changes.
Update : Looks like you are not able to change settings with pysdm due to some bug in it - "No matter what I do with pysdm - Mount file system in read-only mode, still remains checked."
This can be fixed by manually editing /etc/fstab file . Changed
/dev/sda1 /media/sda1 ntfs nls=iso8859-1,ro,umask=000,user 0 0
to
/dev/sda1 /media/sda1 ntfs nls=iso8859-1,rw,umask=000,user 0 0
or even
/dev/sda1 /media/sda1 ntfs nls=iso8859-1,umask=000,user 0 0
and rebooted the system.

This is the file you need to add devices that should be mounted on startup and no there is no reason for these 2 to be not on your system:
These files are not hidden and have to be on your system in order to boot.
Mine looks like this:
You need to find the UUID (look at the comments at the beginning of fstab. You also need to know some other things but you can find these by typing
more /etc/mtab | grep sdd1
Write down what is says there: you need that for editing/etc/fstab
. Editing system files requires the usage of sudo. I would also strongly advice making a backup 1st like so:sudo cp /etc/fstab /etc/fstab.20110521
You can edit fstab with:
sudo gedit /etc/fstab
But be sure to use tabs where appropriate.
