Question about Panasonic LF D521 (LF-D521U) DVD-RAM/DVD-RW Burner
Hello, I have a panasonic LF-D521 DVD drive. It plays disk DVD's ok, but whenever I insert a DVD cartridge it keeps ejecting. I did the test where you unplug the data cable and turn on pc, to see if it ejects during boot and it didn't eject. Any idea's other than trying different media? thanks plopdog
Make a firmware flash to a111 (the original one)
