How can one create a disk image recovery package for their computer?

Really, the easiest way is to just dump everything on your computer onto a CD or memory box. CD's will generally not be large enough, so try and find a large memory box. My friend has a 1 TB box; that's 1 terabyte (1,000,000,000,000 MB) of memory--more than enough (the average computer has at the most a few GB of memory).

If you relay want recovery disks contact the computer manufacturer.
