USB flash drives require full formatting or destruction to secure data

To prevent unauthorized access to sensitive personal information, unused USB flash drives should be thoroughly erased or physically destroyed. Standard file deletion and ‘Quick Format’ options are insufficient for data security because they only hide the file path rather than removing the raw data from the memory chips, leaving it vulnerable to recovery via specialized software.

For Windows users, a ‘Full Format’ is recommended by unchecking the ‘Quick Format’ option during the formatting process to ensure sectors are overwritten. macOS users can utilize the built-in Disk Utility to manage erasure. For highly sensitive data, such as financial or professional documents, experts suggest physical destruction of the internal memory chip to ensure the information is completely unrecoverable.
