Howdy all, I have a fairly newly installed Arch linux installation. I'm having some issues. I am running XFCE and Thunar. I've installed the Thunar VolMan and gvfs as well as verified that I am part of the optical group. I am using an external LG blu-ray disk drive that has worked great on my other distros. When I put a blu-ray in, the link appears in Thunar and it created a folder on my desktop for the blu-ray. However, nothing I can do seems to get MakeMKV to see that drive nor the builtin DVD rom. MakeMKV was built from the Arch AUR. The debug for the app in the log is:

I'm at a little bit of a loss as to what to check next. There are several threads here with similar titles and descriptions, but they are either very old or don't seem related to my OS or particular issue. Anyone have any thoughts?

Have you checked the solutions listed in the other "can't find any usable optical drives" topics in the Linux section?

The vast majority of the posts appear to be Windows OS related so they don't offer me any help. And the few linux ones I have like This one don't have any answers or follow ups and are several years old.

So I'm hoping someone maybe knows the right thread to point me to or has some other ideas. I've covered all the basic stuff. I've removed and reinstalled, I've attempted to run it as root, I've cleared my ~/.MakeMKV directory. No changes.

Drive not been found is a common problem, here is how i fixed it on Manjaro

Open a Terminal, Note: running with sudo does not work
su root
Enter your Password
echo sg > /etc/modules-load.d/sg.conf
Exit
Reboot

After this my drive has been found (pioneer drive)
This also helps for Nero not be able to find a usable drive.

Ah! The generic SCSI module. I didn't even think of that. That was what it was!

And just for reference, you dont need to go through all that reboot non-sense for a kernel module. You can dynamically load it on the fly with:

"modprobe sg"

Which works fine with sudo.

Try adding your user name to the cdrom group.

sudo usermod -a -G cdrom <your user name>
