The Panasonic UJ890 drive used with me on an ASUS UL30 notebook 64bit. The drive we immediately recognized and can be operated without additional power supply. It's enough a normal USB connection. The drive provides good firing results and is relatively quiet (usually it is also not permanent operation !!!). The workmanship is good and all the necessary cables are included. Comparable drives cost more. Big advantage is still the size of the burner - very small as a Slimlaufwerk.
