For sure we will not use kind of a shred program that tries to overwrite files, we will use kind of a dd command with a random pattern, zeros or else. On Thu, 2024-10-10 at 04:57 -0700, Ronald F.

By https://unix.stackexchange.com/questions/229354/how-to-ignore-write-errors-= while-zeroing-a-disk a "sdd" command is mentioned, wich seems to be provided by https://sourceforge.net/projects/schilytools/files/ and it might be available for FreeBSD, https://www.freshports.org/devel/schilybase . FWIW the Arch User repository provides schily-tools-sdd, but Arch Linux doesn't provide a live media. Ubuntu and friends provide a live media, but they don't provide schilytools, but it might build without issues on an Ubuntu or so live media, https://www.unixmen.com/install-schily-tools-on-linux/ .
