1. I'm not sure there is new firmware for that drive yet, but these people keep up with firmware, and I'm sure when a new firmware is released they will post a link to it quickly:

2. Often they improve media compatibility, allowing the drive to make better quality burns with a wider variety of media. Sometimes they enable new features like Mt. Rainier.
3. Recent LG drives use MediaTek chipsets, so you can use MtkFlash to back up your firmware:
4. One way is to run Nero InfoTool, select the drive in the drop-down box, click the "Drive" tab, and you will see the Firmware Version in the upper right corner of the information display.
Replaced mtkflash link with a link to our own dhc014's mtkflash page.
