I have a 40125S and also was having too many errors. It makes no difference what CDR or speed I use. Mine is manufactured in may'02. Had it OC to 48x. I'd tested it with all the FW (in 40 and 48X) availables and nothing. So returned to the original (ZS0F) and uninstalled also the Intel Aplication Accelerator (IAA). Nothing
A few days ago I uninstall all burning SW (I had 3 at the same time: Nero, ECDC and CloneCD) and re-install Nero ONLY, without the IAA and this seems to solve the problem. Until now I had burned 20+ CDs (TDK, Imation, Ritek), at different speeds and get no (zero)errors on the Nero Speed Disk (Scan and quality check).
Can someone confirm if this corrects the problem [?]
I have also a Intel MOBO, P4 @1.7 GHZ, 256 MB RIM, 2x40GB HD and 1 PIONEER 106 DVD. All with the latest firmware/bios/drivers.
Sorry my english. Fernando
