I've already try to find an answer through Sony Global Web site for information but it was a completely waste of time. To my laptop model (VPCF22KFX) only appear Firmware UPDATE (No drivers) for the model Hitachi® DVD-RAM GT30N, and no other answer.
I bought my laptop at a store near my house in Mount Juliet Tennessee US but I'm working now out side of US. I'm really angry and I´ve really feel swindled by Sony, because my laptop suppose to have one kind of CD-RW but really they put inside another one from an old broken subsidiary of sony (of course). and at sony website is impossible to contact to someone (real person No robots) to solve my problem (caused by sony) unless I pay for it at "sony premium support" (very smart of sony to get money).
