Hi. I don't know if this is something had been discussed already, but the question is: Why ISO image reports 1.17Gb when DVD(software) reports 4.12 Gb? Is it something to do with file system, file table or Daemon compresses data to save space on HD? :confused:

Thank you.

What kind of DVD, how did you create the image (software and settings used)?

Problem solved:


I don't know if I overlooked something, but couldn't find any error report in properties. It appears to be bad disk and programm didn't report about it just finished making image. Thank you for responding, Copytrooper. I used Daemon-Tools Panel -> Disk imaging shortcut, that's it.
