I bought a dvdrw drive from radio shack. They had it in a bin of items they were no longer going to stock. It cost me 10 dollars. I stuck it in my computer and my computer recognized it as a Mad Dog TF-dvdrw tsh652n. It reads cds and dvds just fine, but won't burn either of them and the lightscribe feature doesn't work. I went to Mad Dog's website and apparently they aren't in business anymore because the web site doesn't exist. Any ideas?
