After the iso image is burned, the contents of the image cannot be seen

[dddachui]

The rufus software can choose either iso mode or dd mode, and the contents of the USB flash drive can be seen after burning in iso mode
But after I use balenaEtcher, I can't see the contents of the flash drive

[lurch]

Etcher always operates in "dd mode".

I can't see the contents of the flash drive
