What I am trying to do now, but cannot if it is plugged into a
motherboard port, hence the repeat of this exercise on the 2nd sata
card.

This I am still trying to do, the first pass copied all 350G of /home
but went to the wrong drive, and I had mounted the drive by its label.
It is now /dev/sdh and all labels above it are now wrong. Crazy.
These SSD's all have an OTP serial number. I am tempted to use that
serial number as a label _I_ can control. And according to gparted,
labels do not survive being incorporated into a raid as the raid is
all labeled with hostname : partition number. So there really is no
way in linux to define a drive that is that drive forever. Unreal...
Interesting to see in how many differents ways you can use the
term "label". BTW I have no idea what an "OTP serial number" is.
OTP=One Time Pad, never to be used again.

You see that there? You should find this symlink on your system:
/dev/disk/by-id/… …GST02TBG221146
pointing at some random /dev/sdX. Where you put /dev/sdX,
put /dev/disk/by-id/… …GST02TBG221146 instead. Then you'll
know you're referring to that disk. Likewise the others.
