SD Card not reading.. what to do..

I have a built in SD card reader but is not working.. It turned out to be a breeze to get it going.. Follow the link below.. http://goinggnu.wordpress.com/2009/11/12/read-your-sd-card-with-your-ubuntu-laptop/

copying that below....

First, we’ll go into the command line (Applications-> Accessories-> Terminal) and make a backup copy of the file we’re going to modify, which is the modules file in the /etc directory.
sudo cp /etc/modules /etc/modules.bak

Now we’re going to edit the file and add one line.
gksu gedit /etc/modules

Tag this on to the end of the file in a new line:
