Fino all'altro giorno non avevo mai usato il masterizzatore riconosciuto come - Hp DVD-RAM GH40L -, e quando ho provato ad usarlo, sia con slackware che con ubuntu, ho buttato due cd su cui ha inciso qualcosa ma male.
Di seguito incollo i vari output (più o meno simili sia usando slack e cdrecord, sia ubuntu e wodim) sperando che qualcuno possa suggerirmi qualcosa.
Ringrazio e saluto.
