seeing as this is the noob forum i thought it was agreed to answer questions and help even if it sounded a stupid question, but no way as near as the stupid answer you got!
I too have used a benq in place of a liteon, that was in the past when you could spoof one drive to pretend it was another, microsoft got wise to this and now it is no longer possible to spoof. If your box is jtagged or rgh (i think) you can use any drive you like as long as you have injected the correct key for the xbox.
so if you want to go on live, you need the correct drive for your box and the only way you will find that out if your box may have had a spoofed drive in is from your jf log. then simply buy one of that type and inject your key into either stock firmware or the latest iextreme firmware and play your backups
hope this helps
