Probably because you have done other things as well, like you said here:

First of all, let's be clear what you are trying to do.

I think from your first message you are trying to do this:

1. Fresh install of OpenBSD on a new 64 Gb USB stick
2. Test that it boots - OK
3. Erase the files on the partitions that you made using the installer
4. Copy your old files from the 32 Gb USB stick to the new stick
5. Boot from the new stick

That is not the _best_ way to move your existing OpenBSD install to a new
USB drive, but if you want to do it that way it can be made to work.

If that is _not_ what you are trying to do then tell me exactly what you are
trying to do.
