Each subsequent attempt "cycle" fails the same.

I can image /dev/sda1 on the host using dd.

Is this expected behavior?

It works first try if I use a Samsung 256GB 250 PRO SD card + USB reader; image boots to weston. The above is with a SanDisk 32 GB USB3 storage drive known to work on other targets. USB/SD boot is fine to start; it works.
