|Sorry to take so long to get back to you. I tried running System File System Check (sfc /scannow). It blue-screened and took down my system including the MBR. I had to restore from a 2 month old backup. Then, concerned that I may have a corrupted WinnXP system file I repaired XP from the OEM CD. But that was XP SP2. So I then had to download SP3 and then over 125 updates. Took a long time.|
After that, I can use the native XP copy and write to CD and it works. Interestingly, I ran the Microsoft Fixit program and it reported my CD-RW/DVD-Rom drive as non-recordable. Nevertheless it worked ok.
I have an old version of Roxio Easy CD/DVD Creator (version 6) and it cannot recognize any recordable devices when it used to work just fine.
Regarding cdfs.sys being disabled, I see that too but it didn't affect my writing files to the CD-RW drive.
