Painful installs due to faulty disc or something else

Install IS 2012 on two well functioning computers, and whilst it did take out the old copy of  2011 360, it also blew out the dvd drives on both computers.  Many hours latter figured out the disc was the common attribute.  Many more hours latter found the cure for the driver issues on microsofts answer forum.  I urge extreme CAUTION if using the hard copy disc to install.  Sadly, this website is so user unfriendly I am posting here rather than directly to tech support since they make it user unfriendly to have a person to describe their problem to.  I have a love hate with Norton.  Now i remember why!
