The speed of writing is dependent on the rotational speed of the disk, and the i/o bandwidth of the system.
You want to do dd if=/dev/zero of=/dev/rsd1c bs=1m Note that this writes to the sd1 disk! Carefully, carefully look at your disks and write to the correct one. Writing to sd0 is likely to be disastrous. Do this on a test system. dd is as efficient as it is ruthless. You can irrevocably damage a system with it. ---STeve Andre' Sent from BlueMail On Jun 1, 2020, 09:58, at 09:58, Justin Noor <justinnoor...@gmail.com> wrote: >Hi Misc, > >Has anyone ever filled a 4TB disk with random data and/or zeros with >OpenBSD? > >How long did it take?
