I am having the same problem as the original poster.
I just got an external DVD burner, Drive F. Installed the software (CyberLink PowerDVD and Nero 7 Essentials) and the firmware.
But when I insert an empty Verbatim DVD+R into the drive, PowerDVD tells me "No disc in drive F:" (and I have tried using different empty DVD+Rs). And if I try to open Drive F with Windows Explorer, I get the error message "F:\ is not accessible. Incorrect function."
I get the same error messages when I insert a blank CD into the drive.
A few other things that might be relevant:
- Unlike the original poster, I don't think my problem is caused by power issues. Because my external DVD drive is the one recommended by Michael (LG GE20LU10), which has an external power supply.
Just to be sure, I connected the drive to a USB port at the back of the computer (instead of a USB hub), and still have the same problems.
- When I insert a commercial DVD, it does detect the commercial DVD, and can play it.
Can someone help me troubleshoot this? By the way, the store where I bought the hardware has a 7-day exchange policy, so if it is a hardware problem I can exchange for a working one.
