Hi there! I'm interested in converting HD and UHD Blu-ray discs, but I am torn as to which drive to get. This post recommends to buy a native UHD Drive, not a friendly one. Is there much of a difference besides the sleep bug? Also, it doesn't work on the latest firmware. Is it possible to downgrade, and when will it support the latest firmwares? Lastly, I'm on a bit of a budget, so if someone could recommend a relatively affordable drive I'd be most appreciative. Thanks!

This is what we were working on for a while - viewforum.php?f=19 . If you have any issues with LibreDrive mode, please discuss it in appropriate sub-forum. Thanks!

Just for my education can someone explain to me what is the "sleep bug"? It is continually mentioned in various posts, but when I search the forums I cannot find a description. I currently rip UHD discs usually an ASUS friendly drive. Am I just not recognizing this bug? Thanks!

The "sleep bug" is where the drive stops responding because it has gone into a sleep mode, usually because you stopped sending commands to it while selecting what to rip.

When you put a uhd disk in a non native uhd drive after 2 mins of inactivity the drive will go to sleep and not wake up with a uhd disk inside and make a horrible seeking noise it is easily fixed by ejecting the disk and then closing the drive

A minor annoyance at best and certainly not a reason to pick one drive over another. Two minutes is a long time when you're just clicking check boxes come on.

What's that? Oh yeah, Julia agrees with me, total non issue!

Hey all, having an issue and I haven't found an answer after trying for the past week. I have the following drive -

Drive Information
OS device name: F:
Current profile: BD-ROM
Manufacturer: hp HLDS
Product: BDRE BU50N
Revision: BW50
Serial number: KDDG96G1422
Firmware date: 2116-08-10 10:14
Bus encryption flags: 1F
Highest AACS version: 61

Any UHD disc I attempt to rip fails. For example:

Disc Information
Label: WATCHMEN
Timestamp: 2016-05-27 10:57:51
Data capacity: 85.9 Gb
Disc type: BD-ROM UHD
Number of layers: 3
Bus encryption flags: 80

Returns the following error:

I am unclear what is going wrong here. The error states the host cert is revoked, but I'm not sure how that could have happened. I bought this drive in December once I heard official support was coming and it hasn't been used for anything else.

Is the firmware unsupported? Do I need to wait for a new version of MakeMKV with a higher rev cert as some threads imply? I have placed keys_hashed.txt in the defined data directory for MakeMKV and it is putting dumps in the same directory so I assume its in the right place. I have about 10 UHD's, all do the same even ones with older AACS versions like Mad Max.

Thanks for any assistance, it is appreciated.

[jonghotti]

Yes it needs to be flashed with BU40N 1.00 which I am happy to send you. Alternatively I'll swap you a BU50N with supported firmware for yours.

[jonghotti]

The HP branded versions of these slim drives will have some funky firmware version numbers and do not appear to be supported at this time.

Hey would the person I sold a drive to that contained one of my Star Wars blu rays please speak up? I need to get that back

turn on expert mode to see if you get:
Code 03DF - your drive is working fine, you can make UHD backup with it
Code 01BE - your drive firmware version is not yet supported.

Expert mode is on, but I don't see that code anywhere. Where would I find it? One of the dump files?

no it should show up in the window idk why its not maybe another silent makemkv update because when 1.14.2 first came out those debug codes never showed up then just before LibreDrive came out they started showing up so maybe they are gone again.

[SamuriHL]

Yea you need the online update checkbox to be checked.
