DiskFiller is a lightweight space-overwrite utility designed specifically for Windows storage devices. It supports high-speed full-disk fill writing on mechanical hard drives, solid-state drives (SSDs), USB flash drives, and SD cards, helping you proactively expose counterfeit drives (with fake capacity), bad sectors, and drive dropout risks. Additionally, it provides full zero-overwrite erasure of sensitive data space, completely eliminating the risk of data recovery and leakage. Key features: - High-speed concurrent write testing: Quickly fill the entire disk to verify actual capacity and stability. - Secure zero-wipe erasure: Overwrite free space with zeros to prevent recovery of deleted sensitive files. - Wide compatibility: Works with HDDs, SSDs, USB drives, and SD cards on Windows. - Portable and green: Single executable file, no installation required, runs natively. Usage guide: 1. Download and run DiskFiller.exe (no installation needed). 2. Select the target drive from the list. 3. Choose either 'Fill Test' to check for fake capacity or 'Zero Erase' to wipe free space. 4. Start the operation and wait for completion. The tool will report any anomalies found.
