Hi,

I have several thumb drives and had disks. To be able to exchange the
hard disks, all devices are bootable. I have tested the setup some time
ago and it did not give me problems to boot from the external media via USB.

I will take two hard disks as an example:

=>       63  976773105  ada0  MBR  (465G)
         63       1953        - free -  (976k)
       2016  976771152     1  freebsd  (465G)

=>        0  976771152  ada0s1  BSD  (465G)
          0   10240000       1  freebsd-ufs  (4.9G)
   10240000   32768000       2  freebsd-swap  (15G)
   43008000   10240000       4  freebsd-ufs  (4.9G)
   53248000   10240000       5  freebsd-ufs  (4.9G)
   63488000  102400000       6  freebsd-ufs  (48G)
  165888000  810883144       7  freebsd-ufs  (386G)
  976771144          8          - free -  (4.0k)

=>       34  976773098  da0  GPT  (465G)
         34        128    1  freebsd-boot  (64k)
        162          6       - free -  (3.0k)
        168   10485760    2  freebsd-ufs  (5.0G)
   10485928   33554432    3  freebsd-swap  (16G)
   44040360   10485760    4  freebsd-ufs  (5.0G)
   54526120   10485760    5  freebsd-ufs  (5.0G)
   65011880  104857600    6  freebsd-ufs  (50G)
  169869480  806903648    7  freebsd-ufs  (384G)
  976773128          4       - free -  (2.0k)

The system started from ada0. It fails to start from da0 now.

Before I switch the disks, does anybody know of something which causes
the problem?

If this matters, I did this with an X220 ThinkPad.
