Lite-Ons have a single eject button on the right end shaped like a cold capsule (straight, parallel top and bottom with a emicircular ends), a single rectangular red-greed LED, and a single adjustment wheel.
All your CDRW answers are belong to CDFreaks forums, including discussions of how to identify the actual manufacturer of various models and the flashing utilities you'll need to convert to those made by Lite-On to the actual Lite-On firmware.
You can't just flash a rebadged drive with Lite-On's firmware until you convert it, but once you've made the conversion, updates are straight ahead. The software to do it is
mtkflash ver. 1.48 which can both back up your drive's original firmware as a BIN file and flash a new Lite-On BIN file. You will also need
litefirm.exe to extract the BIN file from the current Lite-On Windows flashing file. Read the instructions carefully, and DO back up your original firmware in case you need to return the drive for warranty service on something not related to the flash, such as a broken mechanism, etc.
