yeah right.. it will take approx. 4x4gb DVDs to make urself recovery disks, in the event of a crash of OS, those can be used to reinstall and bring back ur lppy back to factory condition...
wats ur laptop make..?? Sony Vaio...?? watever brand it may be, jus look for the options in the start menu..
and plz (while creating) Recovery Disks, plug in ur lappy's power cord as it will take approx. 120-150mins to create the disks..
