HL-DT-ST_BD-RE BU50N

What is this really? It has stickers that say it was made 23 July 2016 by Hitachi-LG. I've tried the Hitachi ODD Auto Firmware Updater, it just reports the firmware is up to date.

From the info screen from makeMKV, I see this:

OS device name: \Device\CdRom0
Current profile: BD-ROM
Manufacturer: HL-DT-ST
Product: BD-RE BU50N
Revision: AS00
Serial number: KZAG8GJ4516
Firmware date: 2116-08-04 14:24
Bus encryption flags: 1F
Highest AACS version: 68

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

I've found somewhat similar drives on this forum, but not this one. I bought it to use with PowerDVD as part of a spec HTPC that can actually play regular 4K discs, and this errored out. Switched in a new WH16NS60, that works fine.

Really not sure if I should try to keep this, would only do it if there is a reliable path to make this a good UHD ripper - or get it to cooperate with PDVD. I've got another 10 days or less to decide if it goes back. Ideas, please.

You should have gotten a message like "saved FW dump as FW_xxxxxx.tgz. Please send this file ..."
Can you please check your MakeMKV data directory if you have any files named like that? You need to actually open a disc with this drive to get a FW dump.

Got it! I think I've attached the right one.

BTW, Just wondering...

I've got a new WH16NS60, it works great with my PowerDVD, and I don't want to change that. But, why does it not throw a firmware rip as the BU50N did when trying to Backup my Alien disk with makeMKV? Is that because it is already in the database?

It’s a currently supported drive. Read the guide for the current and more popular supported drives:

The forum search will also return dozens of discussion regarding that drive.

Yes, I get that much, that's why I bought it, really. Just wondering why makeMKV didn't extract another copy of the firmware. That's all. I've got the option to use IDE and do firmware the old fashioned way, so thought it might give me a .bin that I could put back after screwing around with MK versions, etc. The dang thing DOES do the freakin' sleep bug, which is ridiculous. Oh well...

Got it! I think I've attached the right one.dump_FW_575820AF2BC1C1912236.tgz
Thanks! Will be supported in a couple days. No flashing required for this one.

Splendid! i guess i won't be sending it back, then. Was seriously looking at a BU40N at NewEgg - with vy good price from MemoryC atm - and one at Bezos.com with "Firmware version- Taiwan R1.01", wondering which would be better. Still not sure why this BU50N won't cooperate with PDVD, but i guess i'll leave it to the WH16NS60. One for the HTPC, one for the storage master! This one is reasonably quiet, and the icy dock 5.25 bay gives me a nice place to put my second Startech 35FCREADBU3. All is good!

Hi Mike,

First off, love MakeMKV and all that you do to support it.
I have a BU50N drive and running into the same thing, with a slightly different firmware it would seem.

Drive Information
OS device name: F:
Manufacturer: HL-DT-ST
Product: BD-RE BU50N
Revision: GE03
Serial number: KZZI5MG2731
Firmware date: 2118-01-22 14:36
Bus encryption flags: 1F
Highest AACS version: 72

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

Not sure if you need this, but the firmware file dump that was created when I tried to rip a 4K disk is attached.

This one would require fw update. Please see email...

Well, I must say it is nice to have working LibreDrive! Firmware version: 0.AS00U popped in when I went to test last night. Thank You!!

Was making a final check in the HTPC box, moved the WH16NS60 out of the way - the effing BU50N still errored, even though Cyberlink UHD Advisor stated all was good. Switched to makeMKV, and backup kicked right in!

That was my professed criteria, so I think I'm still keeping it. It runs quiet enough. I put it back in the Fractal Design R5, when I put the sides back on I probably won't hear it - well, almost. Nice quiet woosh right now.

Curious about one thing, though. The LibreDrive info says 'Unrestricted read speed: Possible, not yet enabled'. If/when higher speed is available, can the rip speed be controlled? I don't see anything in preferences. A two layer disk backed up in ~40 minutes, three layer in ~60 minutes - this is not bad at all, IMO. Faster wouldn't break my heart, but if the little darling starts to rattle or airplane, that wouldn't be good.

Again, giant Thank You for enabling LibreDrive for my BU50N. Third disk in there now - Woo Hoo! Woosh...

Riplock is currently not enabled for any drive outside of testing at least. It will eventually be enabled/released and support announced.

Thanks for that information. That is reassuring! I've never had a drive I thought was really handicapped, but I've read lots about folks changing firmware to fix riplock over the years.

As stated before, I think the current speeds are just fine, and the woosh is the right sound to hear. No need to eliminate riplock here!

Thanks again to all involved.

Howdy Mike,
