Every hard drive or SSD eventually wears down. Failures often begin with subtle errors long before total breakdown. The best way to spot those warning signs is through S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) monitoring. GSmartControl is one of the most reliable tools for this task. It provides a graphical interface for the command-line smartctl utility, making it easy for everyday users to run diagnostics, view S.M.A.R.T. attributes, and test drive health.
But sometimes things don’t go smoothly. Drives may not show up in the interface. Tests can abort unexpectedly. External enclosures might block access altogether.

This article explains how to troubleshoot GSmartControl detection issues and fix common testing problems, so you can keep your drives monitored without interruptions.
Why GSmartControl Troubleshooting Is Important
When GSmartControl fails, it isn’t just an inconvenience. Missing a self-test means you could overlook bad sectors, reallocated blocks, or early failure warnings. A skipped or aborted test can delay data backups and leave you unprepared for sudden drive failure.
By learning how to troubleshoot GSmartControl, you ensure that:
- Drives are always detected correctly.
- Tests (Short, Extended, or Recurring) complete successfully.
- Results can be trusted for making hardware decisions.
- Data protection strategies stay effective.
Common Detection Issues in GSmartControl
1. Drive Not Detected
One of the most common frustrations is when GSmartControl does not detect a drive. Several factors can cause this:
- The drive doesn’t support S.M.A.R.T. (rare on modern HDDs/SSDs).
- S.M.A.R.T. is disabled in BIOS or UEFI settings.
- Low-quality USB adapters block S.M.A.R.T. passthrough.
- Outdated drivers prevent proper communication.
Fixes:
- Verify that the drive supports S.M.A.R.T. monitoring.
- Check BIOS/UEFI and enable S.M.A.R.T. features.
- If using an external drive, switch to an enclosure that supports S.M.A.R.T. passthrough.
- Update SATA/NVMe drivers, as well as chipset and USB drivers.
2. Permissions Problems
On some operating systems, GSmartControl requires elevated privileges to access drives.
Fixes:
- Windows: Right-click the shortcut and select Run as Administrator.
- Linux: Launch with sudo gsmartcontrol.
- macOS: Use sudo in terminal when GUI fails.
Without proper permissions, the software can’t access low-level device data.
3. Virtual Machine Limitations
If you run GSmartControl inside a VM, you may notice no drives appear. Virtualization often hides hardware behind virtual layers.
Fixes:
- Use GSmartControl on the host machine instead.
- Configure passthrough for physical disks if your VM software allows it.
- For critical diagnostics, avoid virtual environments altogether.
Common Testing Issues in GSmartControl
1. Tests Abort Prematurely
Sometimes, a Short or Extended self-test ends before finishing. Common causes include:
- The system entering sleep or power-saving mode.
- Heavy I/O activity interfering with the test.
- Drive firmware restrictions.
- Failing hardware unable to complete scans.
Fixes:
- Disable system sleep before starting tests.
- Avoid multitasking during long Extended tests.
- Re-run the test after a system restart.
- If failures repeat, treat the drive as unreliable and back up immediately.
2. Extended Tests Taking Too Long
Users often think GSmartControl Extended tests are frozen, but in reality, they simply take hours.
Fixes:
- Allow plenty of time (a 2TB HDD may take 5+ hours).
- Monitor progress via the Self-Test Logs tab.
- If multiple attempts fail to finish, suspect drive issues.
3. Inconsistent Results
Sometimes one test passes while the next flags errors.
Causes:
- Marginal sectors that intermittently fail.
- High drive temperature.
- Early-stage hardware deterioration.
Fixes:
- Run tests under stable conditions.
- Record attribute data over time rather than relying on single test results.
- Replace the drive if inconsistencies increase.
4. External Drives Won’t Test
USB-connected drives often won’t run self-tests in GSmartControl, even if detected. That’s because many USB-SATA bridge chips don’t pass advanced S.M.A.R.T. commands.
Fixes:
- Use an enclosure known for full S.M.A.R.T. passthrough.
- When possible, connect drives directly via SATA or NVMe.
- Advanced Troubleshooting Steps
- Update GSmartControl and Dependencies
Old versions of GSmartControl or smartmontools may lack compatibility with new drives. Always run the latest release.
Check Logs
Review the Self-Test Logs tab for details. Error messages often indicate whether the problem is due to user permissions, unsupported hardware, or drive-level faults.
Use Command Line smartctl
If the GUI fails, test the drive with smartctl:
sudo smartctl -a /dev/sda
This can confirm whether the problem lies with GSmartControl or with drive communication itself.
Test on Another System
If GSmartControl consistently fails on one machine, connect the drive to another computer. If the problem persists, the drive is likely the cause.
- Preventing Future GSmartControl Issues
- Keep BIOS/UEFI firmware updated.
- Use high-quality enclosures that pass S.M.A.R.T. data.
- Schedule tests during idle times.
- Back up regularly regardless of test results.
Monitor changes in attributes like reallocated sectors, pending sectors, and error rates.
FAQs About Troubleshooting GSmartControl
1. Why won’t GSmartControl detect my hard drive?
This usually happens if S.M.A.R.T. is disabled in BIOS, the drive is connected through an adapter without passthrough, or administrator rights are missing.
2. Why do GSmartControl tests keep stopping early?
Tests often abort due to power-saving features, high system load, or failing drives. Disable sleep and rerun the test under light usage.
3. Can GSmartControl work with external USB drives?
Yes, but only if the USB enclosure supports S.M.A.R.T. passthrough. Many budget adapters block the commands required for testing.
4. Why does GSmartControl give different results each time?
Inconsistent results often mean marginal sectors are degrading. Track long-term S.M.A.R.T. data trends rather than focusing on single test runs.
5. Does troubleshooting GSmartControl fix a bad drive?
No. Troubleshooting helps you run diagnostics correctly. If a drive shows bad sectors or increasing errors, replacement is the only safe option.
Conclusion
GSmartControl is an invaluable tool for monitoring HDD and SSD health, but occasional detection or testing issues can interfere with its effectiveness. Most problems come down to disabled BIOS features, poor USB adapters, insufficient permissions, or failing hardware.
By applying the troubleshooting steps outlined here—checking BIOS settings, running with administrator privileges, updating software, and using reliable connections—you can restore GSmartControl to full function. With accurate tests and reliable monitoring, you’ll know exactly when it’s time to back up data and replace aging drives.
Keeping GSmartControl working properly ensures that drive health checks remain part of your routine, protecting your data and preventing sudden failures.
