I am having a similar problem. I have tried a number of times to burn a data cd without success and using a couple of different brands of disk too, including ones I have had no problem with before (I'm currently trying TDK CD-R Gold. I've also tried Prime CD_R 52X, which, as I say I've used successfully in the past.
The error I get is :
Error with write address
Sourcefile : Sense Data 05 21 02
There is no problem that I can see with capacity, the last attempt involved less that 500mb.
Any suggestions on how to fix this ?
