You need to erase the disk and use APFS.

hi tnx for the fast answer
i format it to OS x extended (journaled) , GUID. I can see the disk when i am using the old OS
or do you mean other type?

Yes, other type, APFS. But your mac should be able to recognize the USB disk anyway, check the ports and cable. Also, check with ”diskutil list” in Terminal when you have booted with the installation stick. Then all disks should be listed.

It seems you have your install media on the USB disk you are trying to install to, which is impossible. You need to make an installer on a USB pen drive and then install from that to the USB disk.

I see. Then there is a problem with that disk, its enclosure, cable, or port/ports. Try another disk or drive, different cable, different port, and so on.

OP:

Not sure if this will help.

In your original post, look at the 3rd pic from the top (disk utility).
What happens if you go to the "view" menu and choose "show all devices"
????
