Hi there, I've just ruined 40 CD's witch all have errors at 60min. and some of them is starting with the errors at 2min. It's those kind og errors that plays fine in the CD player but just doesn't have excactly the same data as there was in the original file. I've tried 1x,2x and 4x speeds. The controller and burner are both terminated corectly. The burner is testet with IDs from 0-3 with no effect on the errors. I use Sequoia with an Adaptec 2904 and a Plextor PX-W124ST. I've tried TDK and Hispace media. Everything looks perfect when the CD's gets burned until Sequoia is testing the CD for errors and comparing it to the original file. Sometimes I can burn a CD with 40 minutes with no errors ?!? It's like there is a turnpoint at 60 minutes!? Have anybody in here tried this? and what did they do...? ...I've tried almost anything the last 4 days! anything in XP is deaktivated, my PCI buses is empty except for the Adaptec card. And no powersafe or screensaver used.... I'm totally ^#$%ed!!
