Zeero is a Tru64 UNIX command/utility that zeros out disks prior to rewrite.[1]

Purpose

  • It is a more efficient way of writing zeros to a disk (device file) than using /dev/zero with dd.
  • It is a way of data erasure -- removing sensitive data from a disk, or disk partition.
  • shred would be more secure, but is not installed by default on Tru64 systems.
