I was bored… So this is a little bash script i wrote that will write zero’s to a hard disk infinately until you press CTRL+C. It uses dcfldd instead of plain dd because i like the progress output it provides.
#!/bin/bash echo -e "Which disk would you like to wipe out? (sda, sdb, sdc)? \c" read DISK read -p "You picked "$DISK", are you sure? (y/n)" -n 1 if [[ $REPLY =~ ^[Yy]$ ]] then C=1 for (( ; ; )) do echo -e "\nStarting zero Sweep number "$C" ..." dcfldd if=/dev/zero of=/dev/$DISK echo "Zero's written to Disk "$C" time(s)" echo "[ hit CTRL+C to stop ]" let C=C+1 done fi
