GSmartControl vs STB Suite

GSmartControl is a graphical interface for smartctl, used to inspect drive SMART data and run tests. It displays drive identity, capabilities, attributes and device statistics, and automatically highlights anomalies. Users can enable or disable SMART and adjust global or per-drive smartctl options. Saved smartctl output can be opened as a read-only virtual device. The software supports ATA drives, including SATA and PATA, and NVMe drives, plus some devices behind USB bridges and selected RAID controllers. SCSI and SAS drives are not supported, though some information about them may appear. GSmartControl is free software under the GNU General Public License version 3. Downloads include Linux packages, Windows installers and portable archives, FreeBSD ports, macOS packages and source code. smartmontools is a runtime requirement, but official Windows packages include the required software. Useful operations require root or Administrator privileges because operating systems restrict direct hardware access. Supported systems listed include Linux, Windows, FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, macOS and Solaris; QNX support is described as untested.
