Wiping Hard drive

http://forums.fedoraforum.org – Hi All, The standard way I wipe a HDD is to use Code: dd if=/dev/zero of=/dev/sdX many places say that this is not enough and that you need to use /dev/(u)random instead. This however increases the time to wipe the disk from 90mins to 900 - 1600 minutes (500Gb disk). Ignoring whether this is a better way of wiping data etc (many other threads are dedicated to this), I was wondering how the following would compare. If I create a file by doing Code: cat /dev/(u)random) > file.dat and then let this grow to say 1GB and then do: Code: for i in `seq -w 0 600`; do (HowTos)
