Monitoring your hard drive or SSD is essential for keeping data safe. One of the most trusted tools for this task is GSmartControl, a free and open-source application that provides an easy way to access S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data. With GSmartControl, you can run Short, Extended, and Recurring self-tests, check for reallocated sectors, and evaluate your drive’s health in detail.

However, like any diagnostic tool, GSmartControl may occasionally run into problems. Some users report that GSmartControl does not detect their drives, while others struggle with interrupted or incomplete tests. This article walks through the most common issues with GSmartControl detection and testing and provides practical solutions to get everything running smoothly.
Why Troubleshooting GSmartControl Matters
When GSmartControl fails to detect a drive or run a test properly, the reliability of your monitoring routine suffers. Without regular S.M.A.R.T. diagnostics, you risk missing early warning signs of failure. Addressing these issues promptly ensures you:
- Continue running accurate Short and Extended self-tests.
- Keep track of changes in your drive’s attributes.
- Get the full benefit of GSmartControl’s diagnostic capabilities.
- Maintain a proactive backup and replacement strategy.
Common GSmartControl Detection Issues
1. Drive Not Detected in GSmartControl
The most frequent problem occurs when GSmartControl cannot detect the hard drive or SSD. This can happen for several reasons:
- The drive does not support S.M.A.R.T. monitoring.
- S.M.A.R.T. is disabled in the system BIOS or UEFI.
- The drive is connected via a USB adapter that does not pass S.M.A.R.T. commands.
- Outdated or missing drivers prevent proper communication.
Solutions:
- Check if your drive supports S.M.A.R.T. (almost all modern HDDs and SSDs do).
- Enter BIOS/UEFI settings and enable S.M.A.R.T. monitoring.
- Use SATA or NVMe connections directly instead of low-quality USB adapters.
- Update chipset, storage, and USB drivers.
If you rely on external drives, make sure your USB enclosure or docking station explicitly supports S.M.A.R.T. passthrough; otherwise, GSmartControl will not recognize the device.
2. GSmartControl Requires Administrator or Root Access
On many systems, GSmartControl needs elevated permissions to interact with drives.
Without administrator (Windows) or root (Linux/macOS) privileges, detection may fail.
Solutions:
- On Windows: Right-click GSmartControl and select Run as Administrator.
- On Linux: Launch GSmartControl with sudo gsmartcontrol.
- On macOS: Use a terminal with sudo if graphical launch fails.
Always confirm that your user account has the correct permissions to access raw disk devices.
3. Virtual Machine Limitations
If you are running GSmartControl inside a virtual machine, you may not see host drives at all. Virtualization software often abstracts away physical disks, preventing S.M.A.R.T. commands from reaching them.
Solutions:
- Run GSmartControl on the host system instead of the VM.
- Configure the VM for direct disk passthrough if supported.
- For critical diagnostics, avoid virtualization entirely.
Common Testing Issues in GSmartControl
1. Tests Fail or Abort Prematurely
Sometimes a Short or Extended test in GSmartControl ends early with no useful results. This may indicate:
- Heavy system usage during the test.
- Drive firmware limitations.
- Power interruptions or system sleep.
- A failing drive unable to complete diagnostics.
Solutions:
- Avoid multitasking while running Extended tests.
- Ensure your system remains powered and awake.
- If failures persist, suspect hardware damage—back up data immediately.
2. Extended Test Takes Too Long
Extended tests in GSmartControl may last several hours, especially on large HDDs. Users sometimes assume the program has stalled.
Solutions:
- Be patient: a 2TB HDD may take 4–6 hours.
- Monitor test progress in the Self-Test Logs tab.
- If the test never completes after multiple attempts, the drive may be failing.
3. Self-Test Results Seem Inconsistent
Occasionally, GSmartControl reports different results for consecutive tests. For example, one run may show no errors, while another flags pending sectors.
Possible Causes:
- Marginal sectors that intermittently fail.
- Temperature-related issues.
- Drive firmware quirks.
Solutions:
- Run tests under consistent system conditions.
- Check S.M.A.R.T. attributes over time for trends.
- If inconsistencies grow, treat the drive as unreliable.
4. USB Drives Not Supported in Testing
Even if GSmartControl detects a USB-connected drive, it may not run self-tests. This happens because many USB-SATA bridges do not pass advanced commands.
Solutions:
- Use a quality USB enclosure that explicitly supports S.M.A.R.T. passthrough.
- Connect the drive directly to a SATA or NVMe interface for reliable testing.
Advanced Troubleshooting Steps
Update GSmartControl and Dependencies
Outdated software can cause compatibility problems. Always download the latest version of GSmartControl and ensure related packages like smartmontools are current.
Check Logs for Errors
GSmartControl provides logs under the Self-Test Logs tab. Reviewing these entries can help identify whether the issue lies with the program, the operating system, or the drive itself.
Use smartctl Command Line
If the GUI fails, try running smartctl directly in a terminal. For example:
- sudo smartctl -a /dev/sda
This can reveal detection errors or unsupported commands more clearly than GSmartControl alone.
Test with Another System
If GSmartControl consistently fails on one machine, try connecting the drive to a different computer. This helps determine whether the problem is system-related or drive-specific.
Preventing Future Issues with GSmartControl
- Keep firmware updated on drives when the vendor provides safe tools.
- Use reliable hardware connections (avoid cheap USB bridges).
- Maintain regular backups so test failures don’t lead to panic.
- Run tests during low-activity periods to avoid interruptions.
- Check your operating system’s power settings to prevent sleep during long diagnostics.
By following these preventive steps, you reduce the likelihood of GSmartControl detection and testing issues interrupting your workflow.
FAQs About Troubleshooting GSmartControl
1. Why won’t GSmartControl detect my SSD?
Your SSD may be connected through an adapter that doesn’t pass S.M.A.R.T. data. Connect directly via SATA or NVMe for accurate detection.
2. Can GSmartControl test external USB drives?
Only if the enclosure supports S.M.A.R.T. passthrough. Many budget USB adapters block these commands.
3. Why do my GSmartControl tests keep aborting?
The system may be sleeping, under heavy load, or the drive may be failing. Ensure stable conditions and try again.
4. Does running GSmartControl harm the drive?
No. Self-tests are designed by the manufacturer. However, they can stress failing drives—back up data before running tests.
5. How do I fix inconsistent results in GSmartControl?
Look for trends in S.M.A.R.T. attributes rather than single test results. If errors increase, replace the drive.
Conclusion
GSmartControl is a powerful utility for monitoring hard drives and SSDs, but like any diagnostic software, it can face obstacles. From detection failures to incomplete tests, most issues can be solved by enabling S.M.A.R.T. in BIOS, using proper connections, running the tool with administrator rights, and avoiding unreliable USB adapters.
By learning to troubleshoot effectively, you ensure that GSmartControl continues to provide accurate insights into your storage health. Combined with a solid backup plan, regular testing gives you time to act before drives fail, protecting your data and keeping your systems reliable.
