Making disk image from damaged CD

[Viro]

I'm trying to make a disk image from my MATLAB documentation CD so that I don't need to have it in the drive when I launch MATLAB. From what I have managed to find out, MATLAB student edition comes with a documentation CD that contains *many* errors in the first 12000 sectors of the disk.

These errors on the disk prevent Disk Utility from making a disk image. Anyone know how I can get Disk Utility to keep on going and ignoring those errors? I know I can use a Linux utility like k3B to burn the CD, but I just want a disk image so I don't need to remember to bring the CD to uni when I want to use my laptop there.

Companies who do such things with their products are so annoying....

You can try copying just the files you want off the CD, then create a disk image from those files you copied on your hard drive.

Do you have Toast? You could try using that to save as a disk image and then burning that to a new CD and see if that works.

The errors on the CD are there as a sort of 'signature' so that you can't just do a simple copy of the CD. I tried that and it doesn't work. I need to make a disk image that maintains the specific geometry of the disc so that files will be at the correct sectors that MATLAB expects.

I know this is the case, because I can copy the CD in Linux when using RAW read and write. Thing is, I don't want to copy the CD since that means that I can still lose the copied CD and its a hassle since I tend to forget to take the CD with me to uni and then find that I've forgotten it when I'm ready to get some work done (Doh!).

So I figure a disk image is the best way to go since I can't lose it. Now getting a disk image that copes with the errors.... that's my current problem. Does Toast handle this?

It would depend on the amount of corruption. If you have Toast, try it. I've not tried it with a corrupted disk before but that method works perfectly for games. Saves from having to insert discs.
