hi i have nu ddw 061 my dvd read the dvd only and not read the cd or cd-r

i don’t no what the problems i try all firmware but it’s the same plz help me

Could be a bad drive. Retest with another PC. Multiple burn applications can also result in similar conflict.

Did you get this problem after a hardware/software mod?

i buy my dvd and try it but it’s not work and i buy another one now i want to use it but it’s not work with cd only with dvd
