First time & standing on the edge of the roof! I have a Toshiba Satellite L25-S1193. The centerpiece of the cd-rom broke (holds the cd in place). I bought a phillips DVD/CD rewritable (SPD8005BM/17). I replaced it, but my computer doesn't "see it." I'm a novice and shouldn't have proceeded, I guess. My question is: is there a simple explanation? Should my computer have "recognized" it? Is there something I should try before returning it, or hiring help? I would hate to return etc, only to find out it was something simple I 'should've' done. Any help would be greatly appreciated.
