The Benq 1650 is a popular CDR scanner… but beware!
We already know that it doesn’t report C2 according to the usual rules, but there’s something else…
After having used it @24X an @32X for quite some time, I discovered three weeks ago a very, very annoying quirk which makes that most of my CDR 1650 scans are actually useless.
The hidden quirk is: ~ the drive is sensitive to severe disc defects only at slower scanning speeds, @12X being the most sensitive and @16X being the limit to detect the defects ~
The following disc has a big scratch, and has reading issues in all of my drives, including the 1650.
According to the scans performed @24X and faster, the disc has no issue. :a
I could reproduce these results with other scratched discs AND in my other 1650 unit, so it’s definitly not an isolated case.
So much for high-speed CDR scanning with the 1650!
I’ll post advanced scans later.
