Security utility to completely wipe the disk or partition volume selected by user.


TACHYON Disk Wiper is a security utility that completely deletes the disk or partition volume selected by user so that file information saved or deleted in a disk or partition volume cannot be leaked by data recovery software.


Disk Initialization

  • Supports the feature of initializing disk and partition completely.
  • Supports 3 types of disk initialization algorithms, and can initialize disks with the wanted algorithm.
  • Prevents file recovery by repeatedly overwriting data in a disk sector.


  • Supports auto-update

Scope of supporting disk


  • * It does not support RamDisk

Go through US DoD 5220.22-M(8-306. /E) and overwrites it with random single character and do the same ‘E’ process once more




US DoD 5220.22-M(8-306. /E)

Algorithm that overwrites random data and overwrites it with complement of data and overwrites random value once more




Single Pass Algorithm

Algorithm that overwrites all sectors with “0”
