I’m trying to understand what happens with optical drives in general, and failing.

Backstory: I still have a SATA burner mounted in an expansion bay. I’ve been upgrading my pc for 15+ years and that bad boy is still kicking through all the upgrades. I bought a brand new ssd. When I went to plug it in, I realized I had run out of sata ports on my motherboard. I do have a usb portable optical drive so I really don’t need the old burner. So I unplugged the optical drive and plugged in the new ssd into the same port.

Now I knew something would break upon boot, but I didn’t care - let’s learn. It of course hangs on boot. If I undo the optical drive/ssd swap, it boots fine. Manjaro btw. But what file knows about that optical drive that needs to change? It’s not fstab-that’s just regular hard drives (no opticals listed there). Everything says that optical drives get mounted at /dev/sr0, but clearly something somewhere else needs to be deleted ala fstab file style. But what file?

I tried searching optical drive on the arch wiki and didn’t find what I was looking for with a quick skim (maybe I need to read it closer again)

Anyways thanks!

    Did that. fstab uses uuid for identification. If I plug ANY of my drives into that sata port where the optical drive was - manjaro won’t get past login.

    Maybe my manjaro installation is borked and I don’t even know it (it’s actually been pretty good for a while now)

      Interesting… Does the optical drive work on a different port? Does your bios treat that port differently?

        That I have not tried. I’ll try moving them around and see if it’s an issue with that port.

        I’ve moved drives to that one port, but I haven’t tried shuffling all the components around.

        My understanding with sata was that I should be able to move things around all I want. What would change is sda sdb sdc etc, and that’s why you use uuids in fstab. So it was strange to me that I couldn’t plug drives into that first port.

        I’ll shuffle things around more when I get home and see if I can detect any further patterns.

        Edit: as far as I can tell that port is nothing special other than it’s the first one. All the same in bios.
