I've got the same CD-RW drive as you, but it's been rebadged as an Iomega. I'm having problems with it though. It shipped with Nero 5.5, and when I put a CD-RW in, it locks up. I can write and read, but when I try to eject the CD-RW it reboots Windows 2000 Pro. I have to use Nero's eject function as the button on the drive is rendered useless.
It's definitely a Nero problem, because I installed the software on another workstation with an Acer CD-RW. The eject button on the Acer is likewise rendered useless, but the software eject works.
Did you have any problems with your Plextor?
I gave up on Nero, I now use easy CD creator. Works great! :)
