i just purchased a Sony AW-Q170A-10 DVD/CD RW internal drive and hooked it up. when i turned the pc on, it would not recognize it but there was power to drive. the internal CD RW drive that used to be hooked up in its spot works just fine, so i dont think it is a cable issue. this is the 2nd Sony model i have tried. i returned the first one thinking it was defective, both were different models, but both were Sony. my motherboard is an Asus A8N-E.
if you need anymore info on my pc, please let me know.
