I found this write up (at cdrom-guide.com) on installing ASPI drivers when using WinXP:
For some Burnware w/XP you need to install the ASPI manually BEFORE installing
I see where some people were reporting success using ForceASPI however not so with me. After install running ASPI Check determined it was installed correctly, however 2 helpers were not functioning properly.
1) Use ForceASPI's KillAspi.bat
If you have a prior install with the same message I recieved.
2)Go here & D/L Aspi.zip http://xp.xyu.ca/winxp/aspi.zip
3)Run the aspi.bat file & Hit Enter twice
4)Once that's completed, run the aspi32.exe file, select upgrade, and Reboot
Upon XP's restarting you will see a Message
'x# SCSI host Adapters Detected'
Your all set!
