Hi. I have a Garmin topo-map cd, and I am trying to make a backup of it.
I have made several attempts to make a working ISO of it without success.
My dvd-drive is a NEC ND-3500A.
I have tried making iso's with CloneCD, UltraIso, MagicIso, IsoBuster, Nero Burnig Rom and Alcohol 120.
I have tried mounting the images with different versions of Daemon-Tools, and Alcohol 120.
I have also tried making 1:1 copies with nero an clonecd.
Every time i mount the images I get the error message "This program cannot run without the original cd in the drive."
So it's obviously some kind of cd-check.
I've scanned the cd with "Protection ID v.6". This app finds no copy protections, but finds a "possible cd/dvd-check string" in the setup.exe file.
Is it possible to bypass this cd-check in any way, and make a working Iso?
Thanks in advance!
