Verbatim External All In One Optical Writer
It has a Pioneer BDR-UD03 inside, it has been flashed with BDR-UD04 firmware and works with MakeMKV. LibreDrive is enabled and it will read 4K UHD disc.
It has been tested with a 4K UHD triple layer BD100 disc.
Check the pictures for the MakeMKV info and the successful test of the 4K UHD disc, note the serial numbers are the same for the test and the info, this is the drive you are buying.
This unit is brand new, the box was opened, the unit was flashed, and then tested to be sure it works. That is the only use this drive has seen.
Pioneer drives are the best out there for use with MakeMKV and 4K UHD disc. Pioneer no longer makes any optical drives. Get this brand new one before they are all gone and used is your only option.
