Features of "Disk Shredder 4"

  • Can be used repeatedly with no limit
    Having one piece of the product CD-ROM or floppy disk enables you to erase the data of hard disks any number of times or units of PCs. The more you use this software, the more you save the unit cost. Besides, you don't have to count the use of a data-erasure software or licenses.

  • OS is unnecessary
    "Disk Shredder 4" boots up from a piece of media(CD or FD) and erases all the data of a hard disk completely. It does not matter which OS(old versions of Windows or Linux) is installed. It does not matter whether a hard disk includes OS or not.
