Accidents happen. Wear and tear also happens. Over time making 50 cent backups has saved me money over $10-20 on up media replacement costs. And that doesn't even count the home software my kids use that require the presence of the CD in the drive every time its run. Or the hassle involved when you need a CD and it won't quite work. So yes, in a "controlled" environment for CDs only used rarely for installation you can probably get away without a backup. For my purposes, OS install CD/DVDs don't fit in that category because they're often used to boot the computer when hard drive problems appear. So I like to have a backup. Just like hard drive backups, they often don't seem important until you need them. > The humorous part of all of this is that copies of a commercial CD > will normally go bad before the commercially pressed CD itself. But then I can just pull the commercially pressed CD out of the cupboard and make another copy. Doing that, the commercially pressed CD will probably outlast me. -Mike
