I know this thread is already a little aged, but nevertheless I think there hasn’t been major changes to its core statements:
The general rule of thumb for CDR scanning is to do it at full speed, as this is the most difficult test to pass.
That is where the laser has the most trouble writing as the speed is the highest.
Well, on the very same CD I experienced a better C1/C2-Scan @48x than @32x. [Have a look at the attachments: 3897 C1s & zero C2s @48 - 4298 C1s & 1 C2 @32x!]
Scanning drive is LiteOn SOHR-5238S (4S09), a known (fairly) good (enough) scanner for CDs.
I’m a little confused, as this is no single case. I experienced this with some other CDs too that sometimes lower ScanSpeed showed up a worse scan than scanning with max Speed.
Has anybody the same experiences or explanations for this phenomenon?
Which scan can I trust more then?
Thanks for any insights…
