Have had some issues lately with my LG DVD - not sure what the model is ( non Blu-ray tho). No boot up the IDE channel doesnt see the DVD drve even though it is on auto detection in the BIOS. Have taken it back to the place I purchased it from and they managed to get it to be see in 10 quick minutes!!! they said that it had been turned off in the BIOS. But since Im a thickie when it comes to computers I couldnt seem to turn it back on now it has disappeared AGAIN!!!
My main question is have I got some bug that none of the many scans, with the software on my computer as well as online, have failed to ID. Or do I have a hardware issue that need a tech to open up the box to fix??
Have you checked your power and data cables? I've seen this happening when the power/data cables are faulty. Test it in some other system and see how it works out (if you don't have a spare data cable or power rail)
Also, an important point to note is that nowadays it doesn't matter if a drive is enabled/disabled in the BIOS, the OS will always see it regardless.
