Stubborn CDs refusing to back up... (Optiarc AD-5540A)

[qanda]This thread is about the Optiarc AD-5540A. Click here to see full specs[/qanda]Hello Everyone,

I have been able to backup most of my game CD collection using Alcohol 120%.

However, a few games stubbornly refuse to be copied: Carmageddon II, Theme Park World, the play disc from Might and Magic VII…

The cds are not scratched, and CD CHECK ( has not reported a single error so far.

Do you have any advice on this issue?

Many thanks,

I get Disc read errors entries in the log, and they usually start around 800.

I always stop the operations midway.

Disc read errors are normal for safedisc protected cds and, yes, they generally start at about sector 800 (and stop at about sector 10,500). Just be patient and allow the reading process to complete.
