Did you try to read the TOC of a data CD-ROM with cdda2wav too? It might
sound stupid to use cdda2wav to read the TOC of a data CD-ROM, but a CD
recording front end cannot know if there is a data CD-ROM or a CDDA
inserted in the drive.

It might be a problem with the SCSI controllers we use. Which controller
do you use?

I connected both drives to the SE mode connector. And termination should
be Ok. Everything works - from high data rate CD ripping to reading TOC
with cdda2wav. I checked aic7xxx verbose output to check if the
automatic terminators on the SCSI controller are correct too. 3 things
have to come together to cause the problem :

1) I use cdrecord -toc to read the TOC
2) a CDDA disk is inserted in my drive
3) I use my Plextor PX32TS 

If I change any of these 3 items, it works without problems.
