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.
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!
