I have the drivers, but there are two problems.
1. I need to check the license and see if I can send them to you, or get permission from SONY.
2. The drivers are old. The abCD software refuses to install on Windows 2000, and I suspect it will do the same for Windows XP.
Also, you are saying that you have found updates, I have not been able to find any reference to this CD R/W on the Sony site.
I am probably going to try something like Burn4Free from download.com or zdnet.com.
