I see, Aere,

Maybe the method used in the Startup Disk Creator is too complicated, or
the programming is too sloppy, so that nobody really knows what is
happening inside it, and therefore one bug after the other appears.

It is nice when it works, but Unetbootin is much more stable for
creating persistent drives.

mkusb using the cloning method is very simple and just works. Its ISO
9660 read-only file system resists many attempts to overwrite it, but I
have not been able to store persistence in the same drive (only in
another drive, internal or external).
