The gist is format the USB stick (file system doesn't matter) and mount it. Then sudo f3write /mnt sudo f3read /mnt But the thing is, transient errors from USB sticks is a real thing. Also, I once had a USB stick that would transiently corrupt on writes if the dd bs size was too high. I forget the value. But somehow it'd either lose writes or reorder them, and I'd get a completely bootable USB stick but it'd spew piles of file system errors during the installation. https://github.com/AltraMayor/f3 https://fight-flash-fraud.readthedocs.io/en/latest/ > > Side note: With 0207 I once again encountered the white screen sad face. > when I rebooted after the initial install to do the complete the install > tasks.

This could also be transient corruptions on read. USB sticks notoriously do not report discrete read errors, they just return bad data. -- Chris Murphy _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
