What commenters say

• The device can be used to quickly hide sensitive information on a computer when someone approaches, providing an additional layer of security and privacy. Some commenters suggest using full-disk encryption and secure erase methods to protect sensitive data. Others propose using virtual encrypted volumes and mounting and unmounting them as needed to add an extra layer of security. There are different opinions on the best methods for securely erasing data, with some suggesting the use of degaussers or thermite, while others recommend overwriting the disk with random bits or using specialized scripts. The effectiveness of the device in preventing data breaches is debated, with some arguing that it is useful for protecting against casual snooping, while others believe it may not be sufficient against more determined attackers. Some commenters discuss the importance of using encrypted disks and overwriting master keys to prevent data recovery. The use of custom scripts and virtual encrypted volumes is seen as a way to add flexibility and security to the device's functionality.
