Hey folks. I have an HP zx5078cl laptop that came with a Toshiba ODD-DVD SD-R6252 that is I believe only 4X DVD+R/RW capable. I want to upgrade to not only a faster burner but dual format and possible dual layer capable. Anybody had luck with swapping drives in this laptop? Was it good or bad? And what drive and model will fit this thing. I'm thinking there are many that will fit as long as I have the caddy, which I have on the factory drive.
