I'm trying to backup all of my old backup CDs from over 10 years ago to simple DMG files on my harddrive - since CD's die (already have one that won't read) and they take up a ton of physical space!
I've picked DMG files since they're 1) simple/easy and 2) compressed. Certainly open to other suggestions however.
After creating a few of the images, I've noticed that not all of the content from one of the CDs is in the image that Disk Utility is producing - only one of the folders is present when there should be 4. I can't figure it out, but my best guess is that it was a multisession/track CD. But the CD doesn't appear as unique in DiskUtility or in the Finder.
Any ideas what could be the cause? Or is there a better way to do what I'm trying to do?
