GSmartControl review
A free, open-source desktop tool for detailed cross-platform SMART inspection.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GSmartControl is a free, open-source graphical interface for smartctl and the smartmontools package. It is designed for users who need to inspect hard disk and solid-state drive health across Windows, macOS, Linux, FreeBSD, and other BSD-style operating systems. The interface displays drive identity, capabilities, attributes, statistics, and SMART information, while automatically reporting and highlighting anomalies. It also supports SMART self-tests and can enable or disable SMART on supported drives.
Its strongest fit is detailed local inspection across different drive technologies. GSmartControl supports SATA, PATA, and NVMe devices, along with selected USB bridges and RAID controllers. Users can configure global and per-drive smartctl options, giving the tool more control than a simple read-only health summary. Saved smartctl output can also be loaded as a read-only virtual device, which is useful for reviewing previously captured information without connecting the original drive. Integration with smartctl and smartmontools keeps the product closely aligned with the underlying command-line utilities.
The main boundary is scope: GSmartControl is primarily an inspection tool rather than a centralized monitoring system. It suits technicians, administrators, and technically minded desktop users who want graphical access to SMART data, anomaly indicators, configuration controls, and self-tests without paying for the software. It is less suitable for teams seeking a centralized fleet view, continuous operational monitoring, or a broader alerting workflow. Users with specialized USB or RAID configurations should also confirm that their controller or bridge is among the supported configurations. Choose GSmartControl for cross-platform drive inspection; choose another category tool when centralized monitoring is the priority.
