Fujitsu Windows Diagnostic Tool is a powerful utility designed by Japanese IT manufacturer Fujitsu to help Windows users assess the health of their IDE and ATA hard disk drives. This tool offers two types of analyses: a quick test that performs random reading/writing tests and completes in just three minutes, and an exhaustive test that thoroughly examines the disk surface, taking between 30 to 100 minutes. It supports Windows 2000, Windows XP, and Windows Vista, and is also available for DOS. Additionally, Fujitsu provides Diagnostic Tool Ver 2.3 for users with Fujitsu SCSI hard disk drives. Ensure your hard drives are in optimal condition with Fujitsu Windows Diagnostic Tool.

Very helpful! This tool pointed out some glitches I didn't notice. My system is running more smoothly now. I do feel like it could improve the user feedback. Still, a good experience overall.
