Optical Drive not being found

[agressiv]

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?

[dnlaua]

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)

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.

Hey Mike,

I'm having the same issues here with the drive not being found.

Fresh Install: Ubuntu 18.04.3 LTS (Desktop)
Makemkv 1.14.5:
I've tried installing from the Ubuntu Software module, and I've tried manually installing (snap install makemkv)... both with the same results.

Both /dev/sr0 and /dev/sg8 were present after install.

I've tried everything listed here, and still get the dreaded: "The program can't find any usable optical drives."

Any help would be greatly appreciated.

Please disregard my previous post, issue resolved.

To everyone who is experiencing this issue on Ubuntu....

Run

Code: Select all

snap version

snapd MUST be 2.41 or higher.

Run

Code: Select all

snap refresh

As soon as I did this, MakeMKV sees the drive.

[troyBORG]

I have to do this every system reboot:

sudo modprobe sg

Then it will see the drive.

[marknate24]

on Pop_os 19.10 with makemkv 1.14.7 and a usb bd reader.
snap is 2.41
sudo modprobe sg didn't seem to do anything

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.

Glad it worked for you. No luck here (1.15.1 and Ubu18)

[nastyjungle]

Ubuntu 18.04.4 LTS x86_64, was using 1.15.1 and then like the lot of you, makemkv no worky worky now.

Read this thread, installed 1.12.3 (1.12.0 I did not see on http://www.makemkv.com/download/old/)

Fired up makemkv get some fun errors:
Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - AUTHENTICATION FAILURE' occurred
Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' occurred w
Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive

damnit!

Just for giggles I opened 1.15.1 back up, and it seems to be working for now.

What should I do when this stops working again? Should I post any logs or what? (am linux newb)


edit: has stopped working again after i put in the next disc

[nastyjungle]

This is my current error on repeat:

Error 'Scsi error - MEDIUM ERROR:UNRECOVERED READ ERROR - AUTO REALLOCATE FAILED' occurred while issuing SCSI command 460200100..00100 to device 'SG:dev_21:5'

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

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.

Not really. I have been using makemkv on fedora for the past 5 years.

Is your user part of the cdrom group?
if you do "ls -l /dev/sr?" you will likely get something like this

brw-rw----+ 1 root cdrom 11, 0 Oct 7 19:39 /dev/sr0
brw-rw----+ 1 root cdrom 11, 1 Oct 7 19:38 /dev/sr1

As you can see root is the owner and cdrom is the group (in fedora at least) and both have read and write permissions.
If your user is part of the cdrom group you can use the device easily.
