Everything you need to know about CrystalDiskInfo.
CrystalDiskInfo is a free, open-source utility that monitors the health of your HDDs and SSDs using S.M.A.R.T. data. It provides real-time temperature monitoring, health status, and alerts to help prevent data loss.
Yes, CrystalDiskInfo is completely safe. It is open-source software that only reads diagnostic data from your drives. It does not write to your disks or modify any data. The code is publicly available for inspection.
Some antivirus software may flag system monitoring tools as "potentially unwanted programs" because they access low-level hardware information. This is a known false positive. Always download from the official site and verify the digital signature.
CrystalDiskInfo shows three main statuses: Good (healthy), Caution (some issues detected, monitor closely), and Bad (critical issues, backup data immediately). The color-coded interface makes it easy to understand at a glance.
