I have the CW-8123-B, and I can read everything I have thrown at it, but I can't burn data cds. I have a version of Nero 5.5 that is supposed to have support for the drive. I can take MP3s and burn Audio CDs, I can copy audio CDs, I can copy data CDs, but I can't create new data CDs. I originally installed the OS and set it up with a different drive in place, That might be my problem. I have tried different media, but one disk that fails can be put back in and an Audio CD made. OS is Win2k Sp4 and I think I can still burn with the original drive but it is in a USB enclosure now.
This is driving me nuts. It can't read ANY (not even one) data cd. It just spins until explorer gives up. But I was able to rip all my audio cd's to mp3 without any glitch. DVD plays fine too. I have USB 2.0 through PCMCIA if that'd help.
