For the life of me, I cannot find the speed of my computer's DVD burner. Nowhere on the computer. I googled the various model numbers and still can't find it. Help? I am also having trouble finding out about copy/write verification. It seems Windows Explorer cannot verify if my copied files are "perfect". Suggestions? Is write verification only available on after market back up programs? Link to Microsoft answer: http://answers.microsoft.com/en-us/windo...9b-e6e45b21edd5 Does this mean that if I manually back up data by copying files to my backup media, there is no way to verify "exact" copies? But, if I backup through a backup program, that it does verify the information is exactly the same?
