CD-writer can't read media code

I have a Yamaha 2100E 16x CD-Writer.
It is a drive capable of reading the media code from the CD’s.

Since i upgraded to windows 2000 sp4 from windows 98se , it can’t read the media manufacturer code from any cd with any program.
I’ve tried Nero and cdr-identifier but both failed :confused:

I checked again and it reads the media code only on blank-CD’s , but can’t read it from CD’s with data written on them :confused:

Did it read id’s from written media before - I had another drive that could only id blanks, so it is a limitation that can be drive related.

It could read them before even with written media.I’ve been using that feature a lot in the past with CDSpeed and CDRIdentifier.
