For several years now I have used an external PX-716UF with OS X and Toast. I use it both for audio extraction from cds/cdrs and for burning. The problem I am having is that the unit is starting to leave scratches on commercial cds when I am extracting, usually at the distance that the tray has the indentation for the 3 inch cds. Any ideas why this is happening? Is the cd getting clamped too close to the tray or is it uneven?
I had this problem with an older Plextor I purchased 6 or 7 years ago and thought it was unique to it. Plextor never heard of this problem and neither has anyone else with their drives, although it seems to happen often with DJ cd players (the professional Denons I have used at nightclubs for years eventually leave a ring on some discs after lots of play). I am sure few people look at their cds before and after reading but I have always been anal about this, particularly since many of the cds are rare/collectable/valuable discs and many are like new.
If I can't fix this, I will continue to use this drive for burning but am ready to buy a new drive. I need an external with very reliable audio extraction (some rare discs I get from the 80's are somewhat damaged) and perhaps a different parent maker of the drive.
I understand that all Plextors are now rebadges as far as the actual hardware.
Plextor suggested their PX-Q840U (they have terrible customer service and wouldn't easily admit the drives weren't made by them anymore). Any suggestion as to a good external? Perhaps a Lite-On?
