If would take few hours to fill a drive from /dev/zero, but it could take a few weeks to fill it from /dev/random.Īlso, I don't know if Mac OS X does this, but Linux will sometimes block on reads from /dev/random while it waits for more genuinely random input from the outside world (say mouse movements, or network traffic rates or some such). However, if you are anxious to do bad stuff like fill your root drive, then you definitely shouldn't do it from /dev/random, because /dev/random requires vastly more CPU power to generate data for than /dev/zero does. First of all, you shouldn't fill the boot disk of a running machine because it will cause problems, so the hint is a bad idea anyway. "Wouldn't you be much better off using /dev/random instead?"
