Hello, I'm still having this problem. <snip>

For me, it's permissions, as downgrading to 1.10.8 didn't help.

makemkvcon shows drives when run as sudo, but not as a regular user. I've even added myself to the optical group, but I shouldn't have to do that.

Running arch linux. Anyone have any ideas? I don't want to run makemkv as root.

Edit: had to chmod 777 sr0 and sg4. Seems strange that I'd have to do that, but I'll deal with it later.

I came looking here because I had a similar problem, "can't find any usable optical drives". In my case, I'm using makemkv inside VNC (Linux, Fedora 29).

And the fix was "chmod a+rw /dev/sg1"

Hopefully folks Googling VNC, MakeMKV, and doesn't work will hit on this solution :)

Fedora 29
MakeMKV 1.14.3


I have a bluray USB drive (/dev/sr1), but MakeMKV only shows the installed DVD drive (/dev/sr0).

I know the drive works since I used VLC to play dvd's.

Is there a setting somewhere that I missed that can tell MakeMKV where the bluray drive is?

Figured it out after trying to use

Code: Select all

downgrade makemkv
and reading the error message.
First type

Code: Select all

su
Then type password.
Then type

Code: Select all

echo sg > /etc/modules-load.d/sg.conf
Then

Code: Select all

reboot
Worked like a charm
Note I'm on Manjaro, so you may need a different folder than modules-load.d.

Another related problem, check and see if there are zombie makemkvcon processes. If so, they will lock up the drive and when you run makemkv again it can't find any drives.

Only fix I know is to use an external drive (buy a USB3 external case), and power it off/on. This will clear the zombies and next run of makemkv will see your drive as normal.

I am running MakeMKV v1.14.5 linux(x64-release) on Ubuntu 19.04. I have tried everything in this thread and have been Googling for hours to no avail. I've tried loading sg using the instructions but didn't really get anywhere. I can confirm that I have two optical drives (/dev/sg1 and /dev/sg7). They both mount fine within the Ubuntu environment but won't pick up in MakeMKV. The issue started when I updated to the latest version. After exhausting every option, I even tried a clean Ubuntu install - still nothing. There has been a lot of mentions of Docker Containers which is totally new to me. I just installed MakeMKV through the Ubuntu Software store so...

Anyway, I am totally out of ideas and could really use a little direction. Anything anyone can suggest would be much appreciated.

Just updated to Fedora 30 and purchased ($50) MakeMKV

Fedora 30 (x86-64)
MakeMKV 1.14.5

Code: Select all

root> lssci
[0:0:0:0]    disk    ATA      ST500DM002-1BD14 HP73  /dev/sda 
[1:0:0:0]    cd/dvd  PLDS     DVD+-RW DS-8A8SH KD13  /dev/sr0 
[2:0:0:0]    disk    ATA      WDC WDS200T2B0B  90WD  /dev/sdb 
[6:0:0:0]    cd/dvd  Optiarc  BD ROM BC-5500A  1.86  /dev/sr1 
I was hoping that the purchased copy would help with finding the USB bluray drive. Looks like it's still a waiting game for Fedora types.
