CD drivers

I just put in a CyberDrive 24x in my Performa 6115CD. I installed the CD SpeedTools software that came with it. The problem is that audio CD's aren't recognized. I get "This is not a Mac disk. Do you want to initialize it??!!" I've tried many things and nothing seems to help. I'm running 7.5.5. Any help would be appreciated.

I am not familiar with this CD brand, but have you tried looking at FWB's CD-ROM toolkit? It may support this drive model and may even be a better driver to use for the drive.
FWB is pretty dependable and regularly upgraded/maintenanced.
