Hi BillyBob,
I am wondering if it has anything to do with the aspi layer? I am using win2kpro so this is just a guess. I don't think that you need the aspi layer for winxp but I believe that I have read some threads that have said that installing an aspi layer in winxp may help... Use this link to read up a little about it and you may find some useful info.
http://aspi.radified.com/ Also this link to download "forceaspi", a file that allows you to change the version of your aspi layer on your system.
http://www.cyrus.troy.btinternet.co.uk/downloads.htm also download aspicheck to check and see what if any aspi layer is installed before you begin.
I run my CDRW on secondary IDE slave. with a toshiba DVDrom as secondary IDE master. I have heard that you may want to try your drive out as the only drive on the IDE if that is not already the case because some drive types don't play together well on the same cable...
one last thing to ask, is your winxp not recognizing the drive or your burning software? If your using the software that came with the drive this should not be an issue with the burning software...
good luck...
