You are writing a very large file. Does your system work if you use a smaller file?

You have this Roxio driver installed, you might Google it to see what you want to do (CDRALW2K.SYS). I would probably remove it.

NT-SPTI used
Nero API version: 7.2.3.2
Using interface version: 6.3.1.4

You are one of the folks using a Nero 6 interface with the Nero 7 version. I don't know if this would cause problems, but you must not have used the Nero 6 cleaner before you installed Nero 7. I would go back and uninstall 7 and use the cleaner for versions 6 and 7
