Thank you very much for confirming that this is a bug. May I steal your time again and ask what you would do in that situation? Throw away the device because we can't trust it, or format it with 8 bytes of metadata and hope that the PI works correctly then?

In every case, I have seen in the meantime that the firmware on the device is hopelessly outdated. At first, I'll try to upgrade it. If that works, I'll repeat the test and report back.

Thanks again, and best regards,
