Just wanted to say thanks for those replies. After doing a lot of reading around this and other forums I decided to dump my Memorex 12maxx and replace with a Lite-on LTR 52246S.

I ended up using ClonyXXL+Alcoholer+Alcohol120 (all latest versions) and made perfect back-up copies of Sims EP6. So good that I installed and ran the game on a seperate partition using the back-up disks.

It might be a bit of a cop out using Alcoholer, but it worked for me. I suspect changing my burner had something to do with it. Going from no sheep to 2 must make a difference.

Anyway thanks again you guys for pointing me in the right direction.
