well here is the description:
the cd itself is not damaged, since it runs perfectly well but it cant be copied.
i tryed: Nero, cdrwin, clonecd on Smart&Friendly 4x2x24, Toshiba DVD SD-M1402, and my friend's Plextor 8x4
the burning software cant read the disk and reports error, but windows explorer has no problems with it. what do you gurus have to say?
