I have Windows XP system and am computer illiterate - almost - so please be gentle! Recently I had a new DVD drive installed because I was having trouble burning CD discs. The drive concerned is HL-DT DVT-RAM GSA-H55N and I use it mainly to copy podcasts from my hard drive to disc using CDBurner XP. Suddenly I found discs wouldn't burn because CD Burner XP wouldn't recognise there was a disc inserted. Somebody suggested going into Recording tag on Device Manager and making sure there was a check/tick on 'Enable Recording'. It was inticked so I ticked it. And it worked properly again.
