I was planning on partitioning my HD, so I made a bunch of backup DVD's with Nero 7 Premium. All were dual layer data DVD's with close to 8.5 gigabytes on them and nero confirmed each of the volumes before I started. Now that the partition failed I'm trying to move all that data to another computer while I repair the existing one. The only problem is no other computer will read the DVD's. Is there some setting I need to change in the DVD drive of the computer I reading it off of, or are all of these DVD's a bunch of coasters?
