From bios with NO drive it still shows older boot options and i dont
see a way to clear/delete them. ( ami bios ). Soooo i assume its
`efibootmgr` is your friend.
It's the most curious thing.

With the old drives, the front panel LED never lit, even when I was using the new drive I added later.
Now that the old drives are gone and there's only the new one (plus an old spinnyrust for backups of my machines up at the data center), the front panel LED glows red during disk activity.
Same machine, same motherboard, same operating system. These are all SATA drives because I am not cool enough for NVMe yet. What gives? Is there such a thing as a bug on an old disk firmware that would stop all drives from being able to light the controller's LED?
No! So the controller is responsible for the activity light. On NVMe systems, the NVMe controller signals the SATA controller to turn the light on and off, because of course the PCIe bus should be used for such shenanigans. /s
Most likely, the drives were drawing a bit too much current for the LED to light up, and now that you're on SSD you have some current leftover to not starve the light.

My vote too.

Sounds plausible, but the old drives were SSD as well, and the one spinny
disk is still there. The difference in current draw is negligible, unless
a couple of eight year old Intel SSDs really drew that much.
I didn't know about the NVMe to SATA LED signaling. That's pretty sad. Although with NVMe we are probably approaching the end of the era of even having an HDD LED at all. These damn kids and their M.2 sticks! When I was their age a hard disk drive was the size and weight of a brick and had its own LED sticking out the front of the machine!

I've actually extracted and kept the platters from a couple of old disks just for the off chance that some day I can show some whippersnapper and go "back in my day we used to store data on tiny particles of rust!"
