Description
CrystalDiskInfo 9.9.0
CrystalDiskInfo reads diagnostic data reported by a drive through S.M.A.R.T. and displays its model, firmware, interface, temperature, power-on hours, power cycle count, and health attributes. It supports SATA, PATA, NVMe, selected USB bridges, and some RAID controllers.
Features
- overall Good, Caution, or Bad health status;
- temperature and detailed S.M.A.R.T. attributes;
- power-on count and operating-time statistics;
- graphs for selected values over time;
- system tray operation and audible alerts;
- text export and window screenshot saving;
- AAM/APM control for compatible devices.
Version 9.9.0 adds a fake-label indicator for counterfeit Samsung SSDs, JMicron JMS59x support, a fix for JMS586 New, and safer DLL loading.
Important: a S.M.A.R.T. warning does not predict an exact failure date. If a drive is marked Caution or Bad, back up important data to another physical device before spending time on diagnostics.
The official installer comes from the CrystalDiskInfo project on SourceForge. SHA-256: f77a051fc3c1e2d3c662fc8933e0064609da109b5fc3e8bbd17626edc4cf8aef.
