Zeromizer

Free. Generates files populated with either all zeroes, all ones, or random bits.

Uses:
  • Populate drive with files of all zeroes, then all ones, to make free space unrecoverable
  • Populate drive with files of all ones or all zeroes to make a bit-by-bit image (like from dd) much more compressible
  • Populate a VHD with files of all ones or all zeroes to make it much more compressible, for smaller backups
    • Example: I copied and gzip'd a VHD from a virtual machine; the one that had zeroed free space became 2.6gb of 15gb, the other became 6.3gb of 15gb
  • Populate drive with files of random data to make free space unrecoverable
(In the above cases, you would generally delete the 'zero' files as soon as you fill your drive to an acceptable margin)
  • Can be used to dimension a raw disk, which could then be used in Bochs, Virtualbox, etc
  • Can be used to dimension an empty file, then use mke2fs on it, then mount it with -o loop, giving you a super secret "partition"
    • Can also create zero files inside the mounted file to make a backup of it much more compressible


Please don't attempt to use the tool if you don't know what these mean. You'll just fill your hard drive for no reason. May as well poke yourself in the eye while you're at it.
