I only know what I have read, since its on the web it must be true. ;) Pictures help. http://www.howstuffworks.com/cd.htm http://www.howstuffworks.com/dvd.htm use the next page tab at the bottom of each page. My only firsthand experience with a bad backup seems to be a imation cd which has a chip out of the label side on one of the shiny, uncoated bits that make up the background of writing. The cd will load but crc errors are the result on some files. On the other hand I have a OS disc, cracked from the center to the edge which will still install without known problems, can't buff that sucker out. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
