<< The Ricoh 9060A does CDRWs and DVD... >>
Indeed it can, it's a 6x4x24 CDRW and a 4x DVD ROM
They also have a 9120 coming out soon, it's a 12x10x32 with a BURNProof type thingy, and I believe it's 6 or 8x DVD...
I'd venture to say that he has a DVDRom and didn't know it.
An Asus Tray Loading DVDRom looks nearly indentical to their CDRoms for example. And a DVDRom will of course read both.
But a plain simple CDROM can not. (Because of the laser, as has been said)
