i need to replace the CD/DVD combo drive in my laptop. but how do i know what brand fits inside? i was searching on newegg.com and there are a few models by LG and sony, but it doesnt say what laptops these fit in. are all the drives pretty much universal? i have a fujitsu N5010. its pretty much the same as a toshiba laptop. the CD drive currently installed is a toshiba combo drive. i think the drive is pretty outdated so i wanted to get a newer different brand model.
