Using the Fedora 22 ISO available at: https://dl.fedoraproject.org/pub/fedora/linux/releases/22/Workstation/x86_64/iso/ and verified corrected through its sha256sum: $ sha256sum Fedora-Live-Workstation-x86_64-22-3.iso 615abfc89709a46a078dd1d39638019aa66f62b0ff8325334f1af100551bb6cf Fedora-Live-Workstation-x86_64-22-3.iso On 2 different machines (Surface 3 and Lenovo Carbon X1 1st gen) and 2 different USB keys (one Lexar, one SuperTalent), the media verification fails at 4.8% I also tested on both machines using either gnome-disk-utility's "Restore disk image" feature, or dd'ing the image to the device. This is really problematic on the Surface because USB keyboards are sometimes not initialised on boot, leading to verification and failure to boot.
It's possible that the problem is the same as: https://bugzilla.redhat.com/show_bug.cgi?id=1189345 but in my case it might be Windows writing data to that disk.
