Bought DVD-RW discs for additional backups. My laptop has a DVD-RW drive and I checked with device manager and it says its working properly. I checked online for a driver update and it came back that the latest driver is already installed. I put a disc in it and first it didn't see it. After several tries it finally saw the disc and I was able to copy the installer packages I saved as backups. Then when I tried to copy other folders it came back saying the drive is a CD-ROM and not re-writable after I had already moved several folders to it. Now I tried to create a system image and put it on another disc. It formatted the disc and ran the backup. An hour later it came back saying Windows found errors on the disc and canceled the image. Now I insert a disc and it is not even being seen. I encountered this problem on other machines, not just my laptop. Why is this always a problem?
