I have beaten 2.80.10 using the tip with Discdump and Nero.
Clonecd will not work.
Using Liteon 24/10/32s
The game is The Sims Beestenboel (Unleashed)
what version of diskdump did u use?
Where do you download Discdump?
i think that it is ddump 1.10 but the the frontend is 1.4a3.
Final version of discdump is 1.10. You can find instructions for its set-up and use here .
Yoy can also use the freeware burnatonce which incorporates a slightly modified version of discdump. Link to download page and instructions are in the same thread referred to above.
(Interesting that freeware succeeds where commercial software has failed. 
)
I have a TDK 48x16x48 same as a lite-on. I tried to copy Sims Unleashed with clonecd and failed several times. I use the ddump method and came up with a perfect copy, I also found that the easiest way for me to make a perfect copy was to use CDMATE and the default settings for safedisc 2.
this is not only in this case. often freeware will work when commercial fails.:Z :Z
