I have NEC 1300A drive enclosed in usb enclosure (provided as external drive by Cendyne).Works well with DVD+R.I tried using supermedia DVD-R but doesn’t work. Supermedia support says it needs 1.0A firmware. I have 1.06. Can anyone guide me to a detailed procedure for upgrade of usb drives as all I could find here procedures for internal drives which said of disconnecting usb drives.
Windows flasher should work fine on your USB drive!
Download the flasher and test it out!
FYI: 1.0B is the latest official fw.
