    And to clarify - CloneZilla does the trick when boot up
    independently of Fedora, as a live-iso, yes?
    If so then it rather is - as you presumed I guess - OS/software end.
    Then I'd presume that your BIOS has:
    - AHCI and not RAID
    - ports Spin
        Up Device is "Enabled"
        - also there is/should be "SATA Device Type"
        
        I'd play - imagine you did too - with: 'signal-first-then-power'
        VS 'power-first-then-signal'
        
        Other than that Fedora, Centos. which I mostly use which is
        older&behind-Fedora, normally do not need much - I always
        try not to forget to "enable" that in BIOS -> different
        vendor might have different nomenclature for it: hot- plug OR
        swap
        
        I've only glanced at your 'poking' re/scan, I think it's rather
        the host/controller you want to poke.
        If you have not tried already:
        
        echo "- - -" > /sys/class/scsi_host/host0/scan
        
      (& port/connector might want to give/chose
    different)
