Thanks for the reply.

I can burn single CD and it works OK. If I do multiples, I get the error. The media is Ritek. I dont buy off brand CD's and I've never had a problem burning 100's of CD & DVD's in the same drives. The drives are NEC3550A's. Any known problems with Alcohol working with these drives?

I'll see if I have some other media to try, but I think it's a bug. I reported this to Alcohol support. I'm hoping they can test it with the same parameters. I can even send the image (.mds) file if they need it to test. It's about 65mb.

Thanks,

Mike
