If XP does the same thing earlier Windoze OS's do, that might not be a great idea. I've found alt-ctrl-del will freeze all processes until the Close Program window is dismissed. That would really put burn-proof to the test! :bigsmile:
This page has a lot of great freeware monitoring utils, check out "Process Explorer" to see how hard (or not) your CPU is really working:
I can highly recommend it from personal experience.
Slowing down the burn will (obviously) help, but the root cause is that something is hogging your CPU at the wrong time. The drive has a huge buffer, but that means it also takes a long time to fill it when it runs down. There's probably nothing wrong with your drive.
A budget hard disc on a 100/133Mhz bus is probably the likely culprit. The Plextor drives don't seem to use up very much CPU, esp. compared to other ODDs.
Plextor's 8MB buffer might actually be useful for the slower CD burns but at 12x DVD speed (16MB/sec), that's only half a second's worth of data. Better hope whatever's holding up the burn doesn't last longer than that!
