Yeah, so use readcd to make an ISO file from the CD. > Comparing the .iso's md5 > to the original is the way to be sure. Well, if you're going to use dd in a script instead of readcd, why not do it all the hackish way? My point is, by using the right tool to begin with, there's less of a chance of error. readcd knows more about your CD than dd does. > And if you do decide to mount the .iso, be sure to mount it READ-ONLY! > (I've been bitten...
