Darik's Boot and Nuke
Darik's Boot and Nuke is a secure cleaning tool specialized in wiping hard disks of most computers in case of scenarios that involve removing viruses or deleting sensitive information.
The package includes a self-contained boot image (ISO file format) that can be used for creating a bootable CD, DVD, USB flash drive or diskless using a dedicated third-party application.
Expert knowledge required
Taken into account that it deploys an ISO file on your computer, advanced skills are needed in order to tweak the cleaning process. After booting using a dedicated device, the tool simplifies the task by automatically detecting and deleting any hard disk that it can detect.
Where it falls short
Darik's Boot and Nuke is efficient when it comes to wiping every hard disk that it detects on a system. The process may take some time (up to several hours) but this depends on the size of the disk so it is suitable for unattended data destruction scenarios.
On the downside, when it comes to comparing it with Blancco - Pro, the application lacks several professional tools that are used for remapping bad sectors and hidden areas, securely erasing SSD, applying erasure standards for more than 6 passes, and creating XML and PDF log reports.
It cannot handle DoD 5220.2M and NIST 800-88 algorithms, third-party certifications and approvals, RAID dismantling, HW and smart tests, and user authentication. It supports the following HDD connectors: ATA, SATA and SCSI but it doesn’t work with SAS, Fibre Channel and USB.
An overall efficient utility
All in all, Darik's Boot and Nuke proves to be of great help especially for advanced users that need to permanently wipe out data from their computer without leaving any traces behind. It comes in handy if you plan to sell or donate your computer.
