https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D244356 --- Comment #78 from Gary Jennejohn <gljennjohn@gmail.com> --- (In reply to vidwer+fbsdbugs from comment #77) This is an interesting idea. Unfortunately. "yes 1" produces an ASCII '1' = =3D 0x31. It would be feasible to write a bit of C code which writes out an arr= ay of 0xff (all 1s) to a file and then use dd to overwrite the USB stick with = that file. That would be fairly simple. If the file were exactly 1 million byte= s in size then it would be simple to figure out what count would be since manufacturers size things in GB, which is 1000 times one million. So for example with a 128GB stick the command would be dd if=3Dfile of=3D/dev/daX count=3D128000. --=20 You are receiving this mail because: You are the assignee for the bug.=
