What Western Digital Kitfox is
Western Digital Kitfox is a free Windows utility for checking and managing supported WD drives. Device Summary displays device information, speed and security details, and available and used disk space. Device Health monitors temperatures and provides SMART information for supported drives. Diagnostics include a Short Test and a more thorough Extended Test, each returning a PASS or FAIL result. Write Quick Zeros and Write Full Zeros provide erase options; Full Zeros overwrites the media, makes data unrecoverable, and may take several hours. Device logs show configuration and SMART information, while Identify Device reports configuration details. Supported internal retail drives include WD_BLACK and WD HDD models in the Black, Blue, Green, Red, Purple, and Gold families. WD_BLACK P10 and D10 are listed external drives. Other drives may appear without being supported. Windows 11 is the listed operating system, and Kitfox is not compatible with macOS. Western Digital says version 1.1.1.1 included a security improvement to KitfoxService registration.
