Great to hear your drives are performing well, looks like you received a very good BU40N that has performed excellently except for one disc which is very overall for this drive.MrPenguin wrote: Thu Dec 25, 2025 10:46 pmThey are indeed, thanksasmcom wrote: Thu Dec 25, 2025 8:48 am Good to hear from you and I hope the Pioneer BDR-XD08EMB-S, BDR-XD08TG and the Archgon fitted with a Hitachi BU40N drives that you purchased from us are all still running well.. I use the BDR-XD08EMB-S for the actual ripping, and keep the BU40N just for generating dumps for The Powers That KEYDB. The BU40N has only ever struggled to read one UHD disk - "Queen - Rock Montreal & Live Aid", possibly the wide-screen version. The Pioneer reads anything, although I think it also read the problematic "Queen" disk slower than usual.
Curiously, I have been able to run both UHD drives off my PC's USB2 ports without an external power supply. (Obviously not both at once!) I am wondering if this could be because my PC's own power supply is 650W? Plugging a USB hard drive into my PC's (only - it's an old PC) USB3 port, I can still rip a typical UHD in under 1.5 hours.
The BDR-XD08TG is stored in a cool, dry place as a backup.OK, so although it doesn't help us directly, it still means that there will be an ongoing market for releasing new UHD disks. Although not for recordable BD-R XL writable disks, by the sound of it.asmcom wrote: Thu Dec 25, 2025 8:48 amYou’re asking a very reasonable question, and the key point is the distinction between consumer PC optical drives and the OEM mechanisms used in standalone UHD players and consoles.
