CrystalDiskInfo9.9.4

CrystalDiskInfo reads the condition of hard disk drives and solid-state drives, showing health indicators and device information that can help users identify storage trouble early. It can display S.M.A.R.T. data, temperature readings, and statuses such as Caution or Bad for compatible drives.

The utility works with internal storage and supported connected USB devices, while also covering parts of Intel RAID and NVMe configurations. Its partial support across these connection types makes it useful for checking a desktop drive, an external device, or storage managed through a supported RAID setup. The latest email-notification features require .NET Framework 4.8 or later.

Developed by Crystal Dew World, the open-source System Tools software is version 9.9.4 for Windows 8 or later and Server 2012 or later, using the x64 architecture. NVMe support requires Windows 10 or later or Server 2016 or later. It does not support Windows XP or Server 2003, Windows 95/98/Me/NT4/2000, or Server Core.

This release fixes a misleading FAKE label on AMD RC2 RAID and a false positive involving Samsung SSDs under AMD RAIDXPERT2. It also improves Samsung enterprise SSD support, high-DPI handling, and Croatian, Korean, and Vietnamese language files.
