I thought I should prefer the newest drive. The shop offered parallel the 1628.
Fw 1.3 seems not to support PIE errors in CD-DVD speed and probe2.
No options in Nero 6 and 7 to (de)activate SB. In CD-DVD speed (all versions)
SB is not ticked for computer Asus A8N MB with Atlon Toledo48. On older P4 machiche it is ticked, but Nero does not show switch on/off options either.
I detected, that I can change SB however with QSuite 2.1. The help file of QS however seems not to match at all with what I see.
Scan results of CD speed with Sony 720 are mostly fair. Currently I use the Nec4550 as measure, because the results are utmost critical. Dirty MCC 004 I scan between 070 and 097 with 4x burning speed !!! At higher speed the scan results are often 0.
Any contributions are welcome.
