NOTE: The mere presence of this debug message is not an error at all. If the program continues to open open disc after this message, there is nothing to worry about.

29.01.2019 Current status:
The "03" update was just released. You should get the "DEBUG: Code 03DF/03/XXXXXXXXXXXX" and everything should just work. Please reply if it doesn't. Make sure to restart MakeMKV and let it download the updates, if you still are getting "03DF/02" code instead of "03DF/03".

The original bug might have caused your drive and/or SATA controller to hang - the easiest way to ensure that everything is right is to power cycle the device.

For external drive:
Turn off the drive, wait 5 seconds, turn on the drive.

For internal drive:
Shut down the computer, wait 5 seconds, turn on again. Mere reboot might not be sufficient.

29.01.2019 status:
Original bug is fixed, only a small (really!) fraction of users encounter a bug when program prints "DEBUG: code 03DF" and the program and drive just hang. If you encounter the issue, please post the full debug code printed by the program before it hangs. The code should look like "DEBUG: Code 03DF/02/XXXXXXXXXXXX". The fix should be ready by tomorrow, providing you post your debug string.
Thank you!

Original post:
With an update published today, January 26 2019, you may encounter an issue when MakeMKV no longer works for BD or UHD discs at all, producing error code 0272 or 03DF, and failing on AACS. This is a bug, we are working on fix.
This should be fixed in a few hours. If you encounter the issue, please make sure to do the following:

Close MakeMKV if it is running (this is very important!)
Launch MakeMKV, open any BD or UHD disc.
If it fails, please send the produced AACS dump and log file to support@makemkv.com

The bug should be fixed in a few hours. Please do not downgrade to the earlier versions.

Thanks!

This should be fixed now.

I'm still having the same Problem.
The disk hangs at "Analysiere Datei: /AACS/Content000.cer"
MakeMKV v1.14.2 win(x64-release) gestartet
Direkter Zugriffsmodus wird verwendet
DEBUG: Code 03DF

Is there something that needs to be done to get the fix? Because I'm still having the same problem.

Same here

I've tried restarting the application. I've also shut it down, renamed the data directory, and then reopened it. This is what I get when I try opening a blu ray disc:

The point at which I start getting the "OS error - This device does not exist" errors the drive (which is a BU50N connected via USB) stops showing up in the OS. I can send either the SD dump file or AACS dump files if they will help.

Ok. Fixed for most, but now we have a corner case.

Turns out some USB enclosures hang on certain SCSI commands. If you get a code 03DF, followed by debug codes, and then your drive disappears - please send the log and dump to support@makemkv.com. Please write here the model of your enclosure - USB2 or USB3, USB device id if possible, chipset name if you know it.

Thanks!

Hi Mike,

I've run into a similar issue. I just emailed support@makemkv.com with all the necessary information and attachments.

Just posting as a heads up.

Thanks!

Hi Mike,

still got problems, too. (Had DEBUG: Code 03DF, but no program stops...)
I have a drive out of an external one, reflashed to old Firmware and internally setup: SCSI\CdRomHL-DT-STBD-RE__BE16NU50_1.01
Opening a disc or trying to backup program gets a failure and has to be closed.

Before with DEBUG: Code 03DF I could not access the device manager any more and could not normally restart without a reset...

Same issue here too. Emailed my info.

Enclosure Info:
NexStar DX USB3.0 Enclosure
Model: NST-536S3-BK

Drive Info:
LG WH16NS40 Ver 1.02

I can still rip DVDs, but no BD.

Hi Mike,

opening or backuo now just results in a failure and program close for me.
Before today I had DEBUG: Code 03DF and could not normally restart the whole computer after it but do a reset...
Drive is SCSI\CdRomHL-DT-STBD-RE__BE16NU50_1.01 (reflashed external LG internally assembled)

get this when disc is in already before makemkv starting:

Thanks!

I'm experiencing what I believe is this issue as well, although my drive (ASUS BW-16D1HT v3.01) isn't a USB drive, but SATA. I get as far as it "Decrypting" and then I get the "DEBUG: Code 03DF" in the log area, and then it just hangs. Being my first time at the support thing with this, I'm hoping ya'all can tell me: is the dump_SD_<HEX STRING>.tgz file listed in the log output the AACS dump file that I'm supposed to send ?

Thanks!

Please try collecting the debug dump if the program actually crashes, per instructions at http://www.makemkv.com/onlinehelp/dump.html

p.s. That was supposed to be such a small seamless update, that was tested for months...

Mine has been up and running for a few hours now.

Thanks Mike!

It's still not working for me. I'm still getting the DEBUG: Code 03DF error and the drive just won't stop trying to read the disk. If it's now fixed, how do I download the fix? I just purchased a key. I hope I get my instance to work again. I've only tried BD's. Thanks.
