Data Shredder (also known as CBL Data Shredder) is a data destruction utility designed to securely erase a hard disk or digital storage device, completely removing the data and making it unrecoverable. The software utilizes the Gutmann method[1] of destroying data rather than other means of data destruction (such as: ATA secure erase, crypto-shredding, degaussing, physical destruction).

International Data Destruction and Demand[edit]

Widespread need for secure data destruction meant that language-variants of the program needed to be developed to support demand. Coverage of the product in countries like Germany and Singapore led to excessive downloading. A large increase in electronic waste due to high quantities of old computers being thrown out as garbage in dumps and landfills made security of data stored on hard drives a bigger concern of the general public.[2] Data destruction became a part of regular service offerings from the company as press coverage highlighted the step in the data recovery process.[3]
