From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What happens with optical drives (lemmy.dbzer0.com)

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!
