And what will the terminal say to this, for example:
diskutil eraseDisk HFS+ BigData /dev/disk2

"Don't go to the grandmother" - the problem is in three places - in makosi, in combination with a large volume of the disk, and even an external one.
Since the disk itself, together with the container, works on another computer with Windows, then you need to test it on the current computer by installing Windows there.

In my case, it was required to make an EFI 210MB partition on the disk. Mac OS'and it's needed for some reason, even if it's not a boot disk.
After doing so, I was able to break the rest of the disk into the necessary sections and use it calmly.
