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!
Oh ya, forgot to mention that. It boots fine if I just unplug the optical drive. It’s when I plug in a new ssd into the same sata motherboard port - that’s when it hangs. It’s funny - it actually makes it to the login screen, it hangs only after trying to log in. I can’t even break out to another tty terminal.
Edit - the motherboard and chip and ram and video card are all new. It’s the old stuff I’m resuing-case, power supply, old hdds, ect
SSD is sus.
Make an install USB of any Linux. Remove all your SATA devices and install only the new SSD. Ensure that your BIOS can see it properly, and that it can try to boot from the drive with a no os failure. Install your chosen Linux to the SSD and ensure it boots. If it does just wipe it from the live USB again and try with all your previous sata devices connected. Sounds like it's trying to mount the drive and it's got problems or something else electrically is wrong and it's making rhe motherboard lose its shit.
Hmm lots of suspicion at the new drive. I wasn’t as deliberate as you described, but that new ssd now has arch on it and boots fine.
I guess maybe I’ll ask this question. Should I be able to just unplug an optical drive, and plug in anything else into that sata port without linux hanging? I wouldn’t expect the new drive to DO anything until it’s partitioned/formatted/mounted etc. but can I just swap components and expect to be able to boot?
Yes you should be able to safely swap all drives around without any issue, unless you had an unusual setup (such as a swap file, or your bootloader, on a separate drive from your linux install partition).
Sometimes drives can be formatted/initialized incorrectly from the factory. Most drives, especially those for internal use, are shipped uninitialized, aka they have no file table system whatsoever, which linux should handle safely (but maybe it didn't). Less often they are shipped with a formatted file system, usually on external USB drives as fat32 or exFAT, and sometimes that FS can be corrupted real good in my experience. Idk. If its working fine now and passes all its self checks its probably just a weird fluke.
Check your boot order in your bios. Perhaps the optical drive's sata port was first in the order and now the drive is there instead. If this drive doesn't have a bootloader then it can't boot. And since you are tripling booting maybe the bootloader is on a different drive which needs to be first in the boot order.
Edit: Also I would take out all drives and try them one at a time in that first port until i could get one to boot, then I would put the other drives into the remaining slots.
The boot order is uefi hdd (which I can then pick the hard drive’s boot order in a sub menu), then uefi usb, then uefi optical drive, then network. I don’t think that’s the issue - it should always find something to boot before the optical drive.
I’m going to try the one drive at a time in that first port thing and add/move the rest around. I haven’t been as deliberate with the troubleshooting here as I should have (I immediately went towards a software issue - fstab or something similar). I could have a port / mobo problem. Need to separate software from hardware issue better. Luckily I have three installed operating systems on three drives and plenty of bootable isos to play with. ;)
100%. Keep us updated. I personally love a good puzzle.
My vibe is the OS checks the new drive on startup, and gets mad that it’s not formatted instead of moving along.
Oh, in that case it sounds like it is having issues reading the SSD drive for some reason. I have seen system hang trying to read a drive over and over again. Usually the drive is bad when that happens. But it could be a bad SATA cable or maybe some kind of a weird format.
