@brooke that's odd, i haven't heard of this issue on lg drives before.
@brooke oh, huh, they have added built-in firmware upgrade support for LG drives nowadays, I hadn't realized that.
My LG drive is so old that I originally flashed it with the DOS tools that only work with a SATA controller that can be set to IDE mode :)
I wouldn't be surprised if the firmware dump is busted on 1.17.7 for LG drives on Linux too tho (i.e. even though the firmware dump runs without hanging, it won't actually generate a valid dump)
