After going through different troubleshooting steps, my last resort was taking the burner out and trying it in another pc. It worked fine in there. So, I was about to change SCSIs, but decided to hook it back up to the orignal one, made sure the cabeling was in there securely and it worked. So, I should have checked the obvious first. The only reason why I didn't is because my pc had not been moved, changed or anything else. Plus, it was seen in device manager saying that it was working properly. One day the burner was working and the next day it was not. So, that's why I didn't check the obvious first and I should have since that is the first rule of troubleshooting.
