Dell Dimension R450 PII-450 W2K/SP2 via NT4 upgrade. Added HP CD-Writer+ 9900j CD-RW-DVD as 2nd CD. Using HP-provided Roxio software. Problem is that, after a boot the first time I write to the CD drive all seems well ... but after the 2nd time I write, the system hangs, cannot reboot, drive will not eject. Must power off/on !! Good grief. Is there some way to tell what is hung? Some way to avoid power off? DVD works fine. Note that there is no special driver required for the CD. Also, there's nothing on the HP Website of any use. Do you think this is hardware or is the Roxio software screwing things up? At latest version of Roxio as far as I can tell.
