UHD ripping works, but extremely slow

Post by seplant » Tue Jun 23, 2026 11:40 am

I am new to UHD ripping. My drive is a Pioneer BDR-UD04 running LibreDrive. Ripping seems to work with no errors, but it's taking forever. Ripping Transformers (2007) took 8 days. I'm trying Lucy now, and MakeMKV is showing a read rate of 2.3 M/s (0.5X) and estimating 82 hours remaining. My discs look clean. Any suggestions? Thanks.

Try setting the drive to Performance mode.

Right click inside the MakeMKV program folder and open a PowerShell terminal (Windows only, see below for Linux)

Do the following the see the current drive speed setting :

Code: Select all

.\makemkvcon64.exe f -d E: -t pioneer speed get
or

Code: Select all

.\sdftool64.exe -d E: -t pioneer speed get
Replace E: with your drive letter if it isn't the correct one (it could also be D: or F: and so on).

Once you have the drive speed, if it is not set to Performance, do the following :

Code: Select all

.\makemkvcon64.exe f -d E: -t pioneer speed set 1
or

Code: Select all

.\sdftool64.exe -d E: -t pioneer speed set 1
Replacing E: with the correct drive letter as needed.

This should set the drive to Performance mode.

(For the record, I've just checked the values, 0 should be Default, 1 should be Performance, and 2 should be Quiet. 2 is for playing Blu-ray discs quietly with software such as Cyberlink, VLC or Kodi and should never be used for ripping.)

Also make sure that the drive is getting enough power, you might have gotten a USB-A to USB-C adapter with your BDR-UD04, don't be afraid to use that to connect the drive to a USB-C port on a laptop, for example.

If using Linux, do *not* use a makemkv-bin version newer than 1.17.7 and do this instead (this does not need to be done from a specific folder) :

Code: Select all

makemkvcon f -d /dev/sr0 -t pioneer speed get
or

Code: Select all

sdftool -d /dev/sr0 -t pioneer speed get
Replacing /dev/sr0 with the correct device path as needed to get the drive speed.

Then, to set the drive speed mode to Performance :

Code: Select all

makemkvcon f -d /dev/sr0 -t pioneer speed set 1
or

Code: Select all

sdftool -d /dev/sr0 -t pioneer speed set 1
Replacing /dev/sr0 with the correct device path as needed.

EDIT : Once you have done this, if you're on Linux, you can switch back to makemkv-bin-1.18.4 afterwards.

Thank you, Sayaka, for this guide. It may be very useful.

In case of the issue described by the author of the thread, it seems to me that the drive doesn't have sufficient power.
Try to get a USB‑C to USB‑A 3.0 and USB‑A 2.0 Y‑cable and connect both ends to the USB ports.

A good solution, and the one I recommend is to buy a USB 3.0 hub with an external power supply.

Thanks, I'll try this tonight.

My drive came with a USB-A Y-cable, and I have both of the Y connectors plugged into USB ports on the back of my desktop machine. I could try instead plugging into two separate 2A USB power blocks. Would that be better?

I think this won't help. Tell us exactly what kind of enclosure it is. Is it a drive in a Verbatim enclosure, or something else.
Also write what motherboard model is in the computer.

Btw you probably don't need to bother getting 1.17.7 or older. The issue with newer versions affect only non-LibreDrive (perhaps even just some). AFAIK it's nothing "dangerous" anyway.

Wrong. The main issue with newer Linux versions of MakeMKV (newer than 1.17.7) is that they have a broken universal firmware tool. This also seems to be why MakeMKV freezes with some non-LibreDrive drives, it's trying to do a firmware dump and it's unable to do so. If you copy & paste the Windows firmware dump for your drive into your MakeMKV config folder on your Linux OS, MakeMKV is likely to proceed as it should. Same thing if you flash LibreDrive firmware to your drive with your Linux OS with, say, 1.17.6 and then go back to 1.18.4

The guide I posted will likely *not* work with any version newer than 1.17.7, because attempting to run the firmware tool will likely cause the program to freeze. I ran some tests with newer versions on my machine and it's exactly what happened : the program froze instantly. I had to force quit the program with CTRL + C.

EDIT : If anyone wants to test it, it should be relatively simple. Just enter the following command with 1.18.4, for example :

Code: Select all

makemkvcon f -n -t mtk19xx help
This command uses a "dummy" drive to list the dump and rawflash commands for LG MT1959 drives, among other things. So it should always work regardless of whether you even *have* a Blu-ray drive... And yet on newer versions it will freeze.

Ah right. Now that I recall I once wanted to dump whatever can be dumped from my Pioneer drive, and IIRC it did stall.

I suppose the firmware dumping / speed setting bits are not the same bits that are involved in "activating" LibreDrive / disabling bus encryption then...

P.S. It's really weird that mike seems to have no idea what have resulted in the issue. Even weirder is that I saw someone claimed that it doesn't exist on ARM platforms / builds...

If it's the Verbatim 43890, you should have a dedicated external power adapter included. Have you tried connecting the power adapter to this drive? If not, connect the power adapter to the enclosure and plug the single USB 3.0 connector (the thicker one) into the computer. How does the drive behave then?

Regarding the Y‑USB cable, if you are using a desktop PC, plug both ends of the USB Y cable directly into the USB ports on the back of the computer (to the mainboard) rather than the front panel.

If that doesn't help, try checking the drive on another computer or laptop. If you have access to a USB hub with its own power supply, check whether the drive works properly when connected through the powered hub.

Thanks for all the advice. I read where my computer has a USB 3.2 Gen 1 port, so I plugged the main power USB connector for my drive into that, and now it's ripping very quickly!
