Yes, several, but they are all from the same batch of TDK discs.

However, this was a batch of 50 discs, and over the past couple of years I have successfully burned all but the remaining four or five.

It almost has to be a software/firmware thing, because it will burn DVDs flawlessly, but won't even pretend to write to CDs. Well, it pretends to write, in that it says it is writing, but it really doesn't write anything to the disc.

Hmmm... I think my Windows Vista OS has something built into it for writing to CDs, I'll try that and see if it does anything. If it does, I guess that would confirm that the problem is not hardware related.

edit: Nope, Windows won't write to the CD either. Tried several different discs, no dice. Seems odd that it will write DVD but not CD data.

edit #2: Attached is a log file created by the burn failure. Maybe it will make sense to somebody?
