Hello
A lot of people talk about LG BU40N.
I own two drives saying they are BU40N. But they also say HL-DT-ST as the maker. And this, on the outside sticker and on the firmware.

Code: Select all

CD-ROM            HL-DT-ST BD-RE BU40N      A100 PQ: 0 ANSI: 5

So, are they LG made or else ?
Thank you for your knowledge !
Have a nice day.

Hl stands for Hitachi/LG they have a partnership on them.

But see guide below for how to flash or email me or Marty for a automated flasher.

So my drives are made by Hitachi, if I understood correctly.
As per flashing, they read UHD fine and Makemkv is happy also...

To confirm I've just read a Marvel Black Panter II. The backup seems fine but I'll erase it because i'm short on disk space.
Thank you for your response and have a nice day!
