Have a Sony CD-Burner:
I use Roxio and just purchased CD-Rs(8x-multispeed by Memorex)
Roxio doesnt let me append data on a burned cd. I just burned a 10K-file and wanted to added few more files but it doesnt accept the same CD-R, even though it says 'Insert a blank media or media with free space'.
I have another PC which has HP-external-burner-8230
HP's software allows me to do the above(I'm using the same Memorex CD-Rs).
What could be wrong here????
