I'd double check the SATA data cable. Be sure it's properly plugged in. You might try plugging it into a different SATA port on the motherboard. If necessary, you could replace it - those cables are pretty cheap.
Hello everyone, I have an issue with the new DVD drive (LG super multi) I bought. I replaced our old drive (it couldnt write so I had to get a new one) with plugging the same cables to the new one. The mechanics seem to work but Windows doesn't show it. Once I get to device manager, there is nothing (besides of virtual drives). I searched some forums and somebody recommended to check the BIOS whether the drive appears there or not. Well, it doesn't appear of course... I'm not that much of an expert so before tinkering I prefer asking questions from people who know it better... Please help if you have any solution.
