Hi
I compiled and istalled both packages on my linux computer .
It works but , it can't see the optical drive . With or without a disk inside . Mounted or not .
It works fine using a ISO file .It sees and extracts the content .
Here is the content of MakeMKV_log.txt file :

Debug log started at Fri Jan 31 19:31:18 2025 , written by MakeMKV v1.17.8 linux(x64-release)

005042:0000 The program can't find any usable optical drives.

My questions are :
Can I point the program to a location to find the drive ?
Is there such an option , at least from the terminal ?

My drive can be found at /dev/sr0 .
VLC finds the drive , PBurn ( burns discs ) finds the optical drive .

Edit :
I must add that I used an USB attached external drive an old Philips SPB3000CC , which is a DVD/CD drive .
Looking more on the forum pages , I uderstand that my kernel is compiled without SCSI GENERIC support module , which is needed . I shall try to compile and load it.
I'll also open up my desktop , which has no space for a 5.25 drive and try to attach via SATA cables the Pioneer BDR -212V drive I just bought and give a try to MakeMKV .

Both drives showed fine in Windows 10.

I did have the sg module but it was not loaded .
As seen in other forum's posts solved the issue .
Now MakeMKV sees optical drives , even inside usb enclosure .
It's true that when starting the program there should be no disc in the optical drive .
