Hi all,

I've run into quite a weird issue here. I have a BU40N made in 2019 that I was successfully able to flash with the DE_LG_BU40N_1.03_MK.bin firmware. It was running just fine while plugged into the SATA ports in my homelab desktop running Ubuntu 24.04. Then, I decided to turn the desktop into a PROXMOX server, but I was having trouble properly passing the drive through in a way that MakeMKV would recognize. So instead of a SATA passthrough, I figured I'd try a USB passthrough - the only problem was I needed to get a slimline SATA to USB adapter.

Last week, the adapter came, but when I plugged my drive into my laptop (running Windows 11), now the drive is just showing up as a "Generic External" drive. What's more, the SDFtool Flasher is telling me that it's not on the MT1959 Platform anymore so I can't even flash the drive fresh.
I tried to do some digging and found an event in the device properties that says the device settings weren't migrated "from previous OS installation due to partial or ambiguous device match." The date of the event aligns with when I plugged it into my laptop, but I don't know what to do with that information.
Any advice on how to get it back to "specific" and not "generic"?

Just a junky adapter good slim adapters have become very hard to find.

Best to just get a full size sata to USB adapter that works in makemkv from guide and just throw a slim sata adapter on it.

You can even get the owc plus a 9.5mm adapter I sold a few bu40n like this.

Ok, great news! I was able to repurpose an old slim case (from an LG "portable super multi drive") and everything's showing up as it's supposed to! What's more, I was able to passthrough the device via USB to my VM running Ubuntu 24.04 and it shows up in MakeMKV perfectly. I was even able to test out a BluRay disk and it copied over now problem whatsoever.

Thanks for the advice and the reassurance that it was just the adapter, and not anything to do with the drive
