Unless it's the FULL RETAIL VERSION, it's locked to that older CDRW drive. But since you didn't tell the version I can only share the bad news.
i have an e machines t 3092 with a combo burner. want to add external burner. what happens to existing nero software on my machine since new burner comes with nero express oem. do i have to install the new software, or just use existing nero express already on my hard drive?
