Somehow I have deleted or lost the software on my toshiba laptop that automatically reads cd's or dvd's in the drive. When I put in a cd or dvd to install or run a program from it, not only does it not automatically read it, but when I go to "computer", my drive doesnt' even show up there. I have just gotten a new laptop and am trying to install "pcmover" to transfer my files to my new laptop, but can't get the old laptop to recognize/read the cd. What software do I need to reinstall in order for the drive to be recognized so that I can run the software? Thanks!
