Best Practices for Effective Cleaning
Follow these tips to safely achieve optimal results when wiping and optimizing your USB storage devices:
- Use the right software for your specific goals – Don’t rely on a disk defragmenter for military-grade data wiping, for instance.
- Back up important files first – Copy irreplaceable data to another drive or cloud storage to avoid accidental deletion.
- Close other programs during cleaning – This prevents files from being locked or in use.
- Disconnect external drives not being cleaned – Avoid accidentally wiping the wrong drive.
- Run built-in error-checking utilities – Scan for file system and data integrity issues before and after cleaning.
- Defragment after optimizing space – Reorganizes files so they can be accessed faster following cleanup.
- Use wipe patterns that match your data sensitivity – Multiple DOD passes remove all recoverable traces for highly secure data.
- Eject and reinsert USB drives after cleaning – This remounts the drive to reflect cleaned state.
Following security best practices like enabling encryption and strong passwords also helps protect data on USB devices after sanitization.
