OMG i tested it and its really a hardware failure :sad: Sent it back where i bought it. Now waiting... No burning for some time.
BTW: I have a thermalthake tsunami case which not only cools my system, but the whole room . And i'm only using tested media (Verbatim, Imation, Memorex, TDK) so no noname sh!t. Had no problems before.
I had before Plextor PX-W1610TA was really a better drive for burning CDs. I burned more CDs with it and it's still works (my friend has it).
