What GSmartControl is
GSmartControl is a free desktop application for viewing drive health through smartctl, part of the smartmontools package. It displays drive identity, capabilities, SMART attributes, and device statistics, and highlights reported anomalies. Users can run drive tests, enable or disable SMART, and adjust global or per-drive smartctl options. Saved smartctl output can be opened as a read-only virtual device for inspection. Supported drives include ATA (SATA and PATA) and NVMe, plus some drives connected through USB bridges or selected RAID controllers. SCSI and SAS drives are unsupported, though the application may show some information about them. GSmartControl runs on Linux, Windows, macOS, FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, and Solaris; QNX support is described as untested. It is GPLv3 free software. Downloads include Linux packages, Windows installers and portable archives, FreeBSD ports, macOS packages, and source code. smartmontools is a runtime requirement, but the official Windows packages include the required software. Root or Administrator privileges are needed for useful operations because operating systems restrict direct hardware access. Immediate Offline Tests are unsupported. Its SMART information can help with inspection, but good SMART data does not guarantee a drive will avoid failure.
Good
- Displays drive identity, capabilities, attributes, and device statistics.
- Automatically reports and highlights anomalies.
- Runs drive tests and configures SMART options.
- Opens saved smartctl output as a read-only virtual device.
- Supports Linux, Windows, macOS, BSD systems, and Solaris.
- Free software licensed under GPLv3.
Watch out
- SCSI and SAS drives are unsupported.
- Useful operations require root or Administrator privileges.
- Immediate Offline Tests are unsupported.
- smartmontools is a runtime requirement outside the official Windows packages.
Who it suits
GSmartControl suits desktop users who want to inspect SMART attributes, device statistics, and drive-test results on supported drives. It is also useful for viewing saved smartctl output or adjusting SMART and smartctl options, provided the user can run it with root or Administrator privileges.
Verdict
Choose GSmartControl if you need a free graphical way to inspect SMART data and run tests on supported drives. Look elsewhere if you need SCSI or SAS support, or Immediate Offline Tests; SMART data also cannot guarantee a drive will not fail.

The full review of GSmartControl
Overview
GSmartControl is a graphical front end for smartctl that lets desktop users inspect SMART data and run tests on supported drives. It suits people who want drive-health information and controls without relying on a command line. Its free price and broad operating-system support make it a practical utility, though useful hardware access requires administrator privileges.
Key features
GSmartControl displays a drive’s identity, capabilities, attributes and device statistics, and automatically flags anomalies. That makes potential warning signs easier to find during a health check, but the readings need perspective: good SMART data cannot guarantee a drive will not fail.
The app can enable or disable SMART and configure smartctl options globally or for individual drives. It can also open saved smartctl output as a read-only virtual device, which is useful for reviewing a captured report but does not provide controls for the drive represented in that file.
Drive support covers ATA devices, including SATA and PATA, and NVMe, as well as some drives connected through USB bridges or RAID controllers. SCSI and SAS are outside its supported range, even though the app may show some information for those devices. Immediate Offline Tests are also unavailable; they are described as mostly obsolete.
Pricing
There is one plan: Free, at no cost. It includes desktop SMART monitoring and drive-health inspection under the GNU General Public License version 3. With no paid tier to unlock, GSmartControl is a straightforward choice for individual users and organizations that need its supported features. There are no seat counts or usage quotas to weigh.
Platforms
GSmartControl is offered for Linux, Windows and macOS, as well as FreeBSD, NetBSD, OpenBSD, DragonFlyBSD and Solaris. QNX support is described as untested. The downloads include Linux distribution packages, Windows installers and portable archives, FreeBSD ports, macOS packages and source code. Official Windows packages need no additional software; on other systems, smartmontools is a runtime requirement.
Root or Administrator privileges are needed for useful operations because operating systems restrict direct access to drive hardware. That requirement can make the app less convenient on locked-down or shared computers, even when the software itself is free.
Who it's for
GSmartControl fits desktop users who want to inspect SMART attributes, check for anomalies or run drive tests through a graphical interface. It is particularly suitable when a supported ATA or NVMe drive is attached to a system where the user can obtain the required privileges. It is a poor fit for SCSI or SAS hardware, or for anyone who needs Immediate Offline Tests.
Pros and cons
- Pros: Free GPLv3 software provides SMART monitoring and drive tests without a paid plan.
- Pros: Automatic anomaly highlighting and a detailed view of drive attributes and statistics help users identify issues worth investigating.
- Pros: Saved smartctl output can be opened for read-only review, and the app supports several desktop operating systems.
- Cons: Useful hardware operations require root or Administrator privileges, which may not be available on managed computers.
- Cons: SCSI and SAS drives are unsupported, and Immediate Offline Tests cannot be run.
- Cons: SMART data is not a guarantee against failure, so the app cannot make drive health certain.
Alternatives
smartmontools is the natural alternative for users comfortable with command-line tools: it is also free and provides the smartctl and smartd utilities, including the command-line foundation GSmartControl uses.
Consider Hard Disk Sentinel if you want to compare paid software with a limited free trial and Linux or Windows support. DiskMaster, nvm, DRevitalize, Active@ Hard Disk Monitor, CrystalDiskMark and HDAT2 are other listed alternatives.
For related comparisons, see Disk Diagnostic Software, Hardware Diagnostic Software and Disk Health Monitoring Software.
Verdict
Choose GSmartControl if you want a no-cost graphical way to inspect SMART data and run tests on supported desktop drives, and you can access the necessary hardware privileges. Its clear anomaly reporting and wide OS reach make it a useful drive-checking utility. Look elsewhere if your drives are SCSI or SAS, you need Immediate Offline Tests, or you need certainty that a reassuring SMART report rules out failure.
Getting started
