"They might not be included in the drive's firmware" Normally when we buy a DVDRW, if the DVDRW specifications includes CD-RW, we should be able to use any CD-RW disc. Am I right? I understand that bad quality discs causing I/O errors and waste. Does it mean that I have to find the correct drive's firmware that has the Princo CD-RW disc type? How can I verify that? Thanks for your reply.

I have tried to erase these 4 disks in another PC without success. Is it possible that old discs definition are no longer support and not included in the program database? Or simply the physical disc quality does not store and hold data correctly so it becomes unusable after 1 or 2 times!
