Part 1: Introduction to LG BU40N
The LG BU40N is an internal ultra-slim UHD Blu-ray Disc writer developed by LG electronics. It mainly features M DISC support, which is a superior data protection technology, which utilizes a rock-like recording surface instead of organic dye to etch your data onto a disc. It also features silent play, which greatly reduces the noise produced by spinning discs during playback (by automatically adjusting the playback speed according to criteria). With the LG super multi compatibility, you can easily read and write different types of disc formats in one convenient package. The read and write speeds for Blu-ray Discs are a decent 6X, while it is 8X for DVD writing speeds.
The newest LG BU40N ultra-slim Blu-ray Disc writer firmware is version 1.04. Unfortunately, this firmware version makes the device ‘unfriendly’, which is a basic term to describe the advanced AACS2 protection. Fortunately, there is a way to make the device ‘friendly’, and we will show you how to do so. This optical disc drive is compatible with Windows XP, 7, 8, 8.1 and 10. You can get this device for about $95 on eBay, Amazon, memoryC and other participating retailers.
