Solved Hard Drives Always Popping Up As Autoplay

Your SSD has your system volume (your OS) on it but no boot volume, your Disk 4 (G) has no system volume but does have your boot volume so both of these needs to be ‘Bootable’ in your BIOS, none of the other drives needs to be bootable so you can try to see if turning that off makes any difference. While not ideal (your hard drive was plugged in while installing your OS so the boot manager ended up on a different drive than the SSD that your OS is on), it is workable as long as you know that you need both drives to be able to boot. If at any time you need to, or decide to, you can unplug all hard drives and do a start up repair on just the SSD drive.
I see nothing more obvious that could be causing the problem, though you may get some more information by running Seatools test on each of the drives that are the problem ones to see if there are any problems with the drives (but being on two drives, that seems unlikely).
You also may want to make sure that all SATA cables are plugged in fully and are at least the full speed of the drives (SATA II/SATA III).

You have to be a little bit crazy to keep you from going insane.
