The latest version from Fedora Repo is f3-8.0-8.fc41.x86_64 There is a newer version on https://github.com/AltraMayor/f3 Link to download latest https://github.com/AltraMayor/f3/zipball/master Change log show Version 9.0 - Mar 27, 2025 * f3read/f3write: Avoid the execution stack to list files * f3read/f3write: Add dynamic buffers * f3read/f3write: chroot(2) to source/target dir if allowed * Portability improvements for Ubuntu, ARM, OpenBSD, and Apple * Automated test of the code with GitHub Actions * Improved documentation Version 8.0 - Oct 29, 2020 * f3read: add parameter --max-read-rate * f3read: report speed, percentage, remaining time like f3write * f3write: improve speed measurement (commit 791acdc32627...) * f3probe: handle rare assertion failure (issue #82 ENODATA) The files it includes are f3brew f3fix f3probe f3read f3write Have found it useful for testing USB devices. It finds fake devices, and can try to correct to real size, which is usually very small. Generally, just throw away fake USBs. Good Luck. > > -- > George N.
