Problem solved...
I did a complete uninstall/reinstall of the drive.
1) flashed firmware to latest (didn't solve problem on it's own)
2) removed all dvd drives from device manager
3) removed ide controller from device manager
4) shut down computer
5) unplug all power and data cables going to drives
6) system bios - disable ide controller (sata controller still enabled)
7) reboot into winxp (restart a couple times, run cc cleaner, etc)
8) system bios - enable ide controller & reboot into winxp
9) shut down and reconnect cables to dvd drives (1 at a time) and reboot so win reinstalls
everything works
Thanks for the help
