Be more accurate when using the example of the mbr.

If you erase your first 512 bytes, you are most likely erasing your
partition table as well.  And there is no way the grub plugin will
be able to recover anything without a partition table.

 Sometime after receiving fedora 9 from his hacker friend, Joe gets the word that fedora 10 was released with a bunch of updates that might be interesting to him.  Being a curious and adventurous person by nature, Joe thinks its a good idea to upgrade his system, so he gets his hands on a fedora 10 DVD and fires up the upgrade process.  As usual its a very user friendly interface and after answering some configuration question that he does not completely understand, the upgrade finishes successfully.  Joe is eager to restart his laptop to begin to use all the wonderful updates that he had read about in fedora site.  So he reboots and waits impatiently for the system to come up again.
 
-Success!, fedora has upgraded to its next major release.  Joe is happier than ever.  He is so happy that he begins to look for more information on the new release.  In all his searching he comes upon a site that tells him how to modify the background of his grub.  He has a really cool image that he thinks would look really nice at the grub menu.  He decides to follow the instructions on this particular site and see if he can make his cool idea work.  When the tutorial tells him to backup the first 512 bytes of his hard drive he gets mixed up and copies `dd of=/dev/zero of=/dev/sdb bs=1 count=512` on the command line, with root access.  He completes the rest of the tutorial and reboots when he thinks he is done.

He completes the rest of the tutorial and reboots when he thinks he is done.
 
 Joe waits a couple of minutes before realizing that the black screen with a white cursor at the top left is not the expected boot screen.  He feels scared because he does not have any other way of booting the system and all his work for the semester is in this particular computer.  He immediately thinks about all the important information that is contained inside and starts panicking.  He reboots the machine several times to find that the behavior does not change.  In a state of complete panic he calls Fred.  Fred's girlfriend picks up and says that Fred has gone out of the country and left his cell with her until he comes back.  But, Joe is not discouraged and he goes to a friends house to get on the web and try to find a way to fix his problem.  He spends the weekend trying to make his notebook boot with no success.

 \section{What is Firstaidkit}
 Firstaidkit is an automated recovery tool that brings together common recovery processes and applies them to a system.  The way that Firstaidkit handles the recovery processes is by means of plugins.  The idea being that a plugin will focus on a particular issue in the system, like grub, init scripts or Xserver.  Firstaidkit is designed to automatically fix problems while focusing on maintaining user data integrity.  In other words, Firstaidkit will try its best to fix your system while maintaining your data intact.
 
-Here we can recall Joe's situation.  Lets recreate the end of the story with the only difference being that Joe had Firstaidkit on a rescue disk or liveCD.  Joe just wants his computer to boot, he knows that he somehow shot himself on the foot, but now he would want an easy way out.  In this case Joe may run Firstaidkit in diagnose mode to see what is wrong with his system.  Firstaidkit will notice the missing grub in the first 512 bytes of the drive and will tell Joe that he needs to fix his grub.  After looking through the Firstaidkit man pages and searching through the plugin list, Joe finds that he needs to run the plugin named "grub".  He tells Firstaidkit to run grub in fixing mode and reboots his machine after the process ends.  He waits impatiently for the machine to go past the blank screen with the cursor at the top left.  When the computer boots normally, Joe is very pleased that all his information was not lost and continues his daily activities.

 Joe's situation is just one of many in which an automated recovery tool would make peoples life easier.  It is not restricted to the Linux user that is a beginner and can be extended into administrator recovery tasks like a SELinux analysis process, deleted partition recovery process, init scripts recovery, rpm database recovery, etc.  The list extends into most, if not all, the OS subsystems.
