Thanks I trust the experts here then. I got a bigger amount of the Verbatim 43888/BU40N already ,also to sell. Will simply rip one out and get a 5,25 adapter kit then.

Thanks but that is in the USA? I am located in Europe, Germany. So you would prefer a slim BU40N in an adapter over this Asus? What I mainly dislike is the tray and that you must put it in manually after eject. From the BU40N slim ones I got quite a lot

Well I am looking for a new 5,25 drive that can run libredrive. The only option I found is this ASUS TurboDrive BW-16D1X-U. But it comes in an external case and does not say which drive is inside. I would like to take it out of the case and use in a normal PC tower. From reading here a bit I found ...

Well I got a few of these fullsize 5,25. On official firmware they can`t do 4k.
Can you really just flash them to enable that mode?

Drive Information
OS device name: H:
Current profile: CD-ROM
Manufacturer: PIONEER
Product: BD-RW BDR-209D
Revision: 1.51
Serial number: nope
Firmware date: 2018-05-08 ...

Well anyone interested can write me an email with his location for a price quote. 2 drives in one packet are also possible.
All are new, opened only for the flash. I will ship in the original Verbatim sales box with all cables and a nero burning rom software on cd.
Packed into a neutral carton box ...

Well I got a bigger stockpile of exactly that model. It is the 43888 with the 4k UHD sticker on the box.
HL-DT-ST BD-RE BU40N model running 1.05 firmware out of the box.
Flashing to 1st 1.03MK and then to 1.00 worked fine and shows up in makemkv.
Some boxes are laying around here for maybe 2-3 years ...
