Toshiba laptop upgrade



Hi guys,
I decided to upgrade my Toshiba Satellite M35-S359 to the DVD burner side.
After browsing around I found many post about Toshiba issue with DVD hardware.
So I contacted Newegg about my upgrade plan and they reply with a nice letter, but they don’t provide any informations about hardware compatibility.

So my question is :
How to be sure my “old” laptop will work with a brand new DVD-burner before installing the hardware ? or it’s a russian roulette game or stuff…

Thanks to clarifying the situation. :confused:
