My CD-RW drive is the AOpen CRW-1232Pro. I have Windows XP and I'm using Nero 5.0. I've been burning all kinds of things to CD-Rs with no problem since I bought the drive last year. But a couple of days ago I tried to burn to a CD-RW for the first time. Every time I tried I got a message asking me to insert a blank media even though the CD-RW was already in. I bought a pack of 5 CD-RWs (700MB) and I've tried 2 so far with the same results. They are meant to be recorded to at 4X (or lower) which is the speed that I tried. I went to the AOpen website and downloaded and installed the latest driver they have. That did not fix the problem. I don't know what's wrong. Any help will be deeply appreciated.
