dd is a utility to create a disk dump by reading every single block on a disk, e.g. your hard drive. Its architecture is laid out so it can do much more than creating a dump. Here is what dd can do for you:

  • manage a disk backup
    • create a backup from a disk to a file
    • restore a backup from a file to a disk
    • clone a harddisk
    • create a disk image and transfer it over the network
  • create an iso image of a CD
  • rescue a file that contains bad blocks
  • analyze your disk by displaying selected blocks
  • create your own operating system by dumping your bootloader to the boot sector
