I've also been having problems with SafeDisk 2.8 disks (specifically SimCity4 and Civ3), only my problem is that I can't even get an image from them. I've tried Clone-CD, Alcohol, and BlindRead. But all that happens with any of them is that I get about a million read errors.
My burner is a MSI 52x24x52 CD-RW drive, and I've also tried to get the image using my MSI 16x DVD drive.
The disks look and work like new, so I don't think it's a physical problem with the disks.
What should I try next?
