I have a problem with my DVD-RW. Whenever I try to install games in my computer, the installation process stops randomly and a message will pop out, showing a cyclic redundancy check error. When I checked it in the Event Viewer, the log says "The device, \Device\CdRom0, has a bad block." The only way to install the games was ejecting the CD/DVD when the error pops out then reinserting it again and the installation would continue its progress. I'm pretty sure it's not a faulty CD/DVD because it happens in almost all of the games that I'm attempting to install, so I guess this has something to do with the DVD-RW. I'm thinking that the DVD-RW is defective, but I've been using it for only a month so maybe that's not really the case.
