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!

    Thanks for all the help! Lots of good suggestions in this thread I can try for further troubleshooting. Most importantly, you all confirmed I should be able to unplug an optical drive, put in a new unformatted ssd, and generally move drives around - and linux should still boot. I did not think things would behave that way, so when I had issues I figured it’s of course pilot error. Also explains why I was having such a hard time finding information on the arch wiki ;)

    Now I know something ain’t right, and my guess is its some user configuration (because it does boot, it just hangs later). This has now turned into a side project (what the heck did I break), I’ll update the thread if I figure it out. It’s a pretty clean install, very few AUR packages (mostly flatpaks), and has been otherwise pretty stable-it’ll be interesting to see how it actually broke.

    Thanks for the suggestions!
