  • Can I dd copy an sdcard image to a USB stick for a Pi 4B?

    From Chris Green@3:633/10 to All on Mon Mar 9 16:51:00 2026
    Does a bootable USB stick for a Pi 4B have the same format as a
    bootable SD card? I.e. can I just use dd to copy one to the other
    (not on the Pi itself) and expect it to work?

    My experience is that you can.

    While I don't understand the 'format' bit, yes you can absolutely dd a USB to and SD for a Pi image...

    dd if=/dev/xxx of=/dev/xxx

    (There are other options you can use that I prefer;)

    dd if=/dev/xxx of=/dev/xxx bs=4M status=progress conv=fsync

    Find USB/SD devices:
    lsblk

    Verify write after dd:
    sync
