When I want to copy a CD, the process starts with “Scanning Tracks”: The burner jumps to each track to verify the correct starting points (please correct me, if this is wrong). The copy process starts after this procedure.
(The same procedure is also done, when one is testing c1/c2 errors).
Normally the “Scanning Tracks procedure” lasts for some seconds (no matter if CDRs oder manufactured CDs are read). But sometimes the procedure lasts some minutes (more than 5 minutes!!), especially with older CDs (manufactured in the 80ies). The burner is searching very long for each starting point, then for the next one etc. When testing these CDs, the error rates are normally low, thus this seems not to be the problem.
Used Software: Plextools Prof
Burners: Plextor 48-24-48, Plextor Premium, Plextor 712 (all are external burners). All burners show the same problem.
