Actually, another option is to put the legacy OS into a VM where it

Then you can LVM this external drive instead of partitioning it, and
then make an LV (or two or three or whatever) to use as backing for
the VM, and then those VMs will see each LV as a drive, which you can
partition and format with that legacy OS's tools however you want. Or
use qcow2. Lots of options.
Very interesting. Very worth trying out.
Thanx!!
This being an MSDOS partition you're talking about, there is a concept
in the Windows world known as an active partition. I don't know if it is
germane to this discussion, so I haven't raised it until now.
Microsoft's CLI took for manipulating disk partitions is a called
diskpart. The online documentation for diskpart says this about active
partitions:
active
On basic disks, marks the partition with focus as active. This informs
the basic input/output system (BIOS) or Extensible Firmware Interface
(EFI) that the partition or volume is a valid system partition or system
volume
Only partitions can be marked as active.
Important
DiskPart verifies only that the partition is capable of containing an
operating system's startup files. DiskPart does not check the contents
of the partition. If you mistakenly mark a partition as "active" and it
does not contain the operating system's startup files, your computer
might not start.
I have no idea about the mechanics of active partitions (i.e., which
bits get flipped to make a partition "active") It may be what you have
been discussing all along, but I thought I but this on the table. Seems
to me that if you mark a partition as not active, the BIOS will not try
to boot from it.
Or not.
Ignorance is my superpower
