Ok, so my DVD drive started giving me trouble. If blank media was inserted it gave me a "drive not accessible" message. Then it started doing it with all media. i updated firmware and also the mobo drivers to no availe. In the BIOS it showed that I had a LITEON L18***** whatever, but under My Computer it said CDROM. Click on properties, it said what it was, and no faults found. So as it was 3 months old I rang the supplier and told them, they said send it back and they'd check it out. 3 days later I had a new drive on my doorstep, now a LITEON L20 version. Plugged it in, and ARRGGGH, same problem! What is the likelyhood of it being DOA? what else should I be looking at? Again, BIOS recognises it, but if you double click on the icon with or without a disc in it says "drive inaccessible"
