Disk wiping is the process of securely erasing data from a storage device, such as a hard drive or solid-state drive. This is done to prevent unauthorized access to sensitive information, ensuring that deleted files cannot be recovered by data recovery tools. There are various methods for disk wiping, including overwriting the data multiple times with random patterns or using specialized software designed for this purpose. This is particularly important when disposing of or selling devices, as it protects personal information and complies with data protection regulations, such as those outlined by GDPR.
