GSmartControl
GSmartControl 2.0.2 is a cross-platform graphical interface for smartctl. It reads SMART identity, attributes and logs from HDD, SSD and NVMe devices and can start short or extended self-tests.
What GSmartControl provides
GSmartControl 2.0.2 presents smartctl data in a graphical interface for HDD, SSD and NVMe devices. It can show identity information, attributes, error logs and self-test history, then start a short or extended test when the device is stable and the data already has a separate backup.
Reading health signals
A device-reported PASSED state is evidence, not a guarantee. Vendor attributes, thresholds and raw values differ, and interface errors may come from a cable, bridge or controller rather than the media. Compare reports over time and protect data before running a long test on a failing drive.
Platform and hardware boundaries
Windows, macOS, Linux and BSD packages or builds are available, but USB bridges, RAID layers, virtual machines and permissions can hide or transform SMART commands. Record the model, serial number and connection path before acting. Review date: 2026-08-23.
Save to your cloud drive
Open the cloud drive to get the file directly, or save it for convenient access on another device.

GSmartControl 2.0.2 disk-health and self-test guide
Begin with read-only inspection, identify the correct physical device, save a baseline report and only then decide whether a short or extended test is appropriate.
Before you start
- Finish at least one independent backup; if a drive clicks, disconnects or reports many read errors, prioritize data recovery over testing.
- Prepare administrator or root access because physical-device SMART reads commonly require elevated permissions.
- Record the model, serial number, capacity and interface so the test cannot be applied to the wrong drive.
Installation steps
- 01
Choose the platform package
Use the Windows installer or portable ZIP, or the trusted package or build for macOS, Linux or BSD, then verify that the displayed version is 2.0.2.
- 02
Start with necessary permissions
Refresh the device list without changing standby, automatic offline or SMART settings, and identify every drive by model and serial number.
- 03
Save a read-only baseline
Open identity, attributes, error logs and self-test history for the target device and save the report so later changes can be compared.
Quick start
- 01
Review logs and key attributes
Look for unfinished commands, media errors, reallocated or pending sectors and interface errors, while interpreting vendor raw values with the device context.
- 02
Run a short test first
Pause workloads after backup, start the short test and wait for the device estimate; avoid sleep, unplugging or heavy I/O until the log is updated.
- 03
Decide on an extended test
Start an extended test only when the connection is stable, the data is backed up and a longer surface check is useful; stop if new errors or disconnects appear.
Usage tips
- SMART trends are more useful than a single green status; compare attributes, logs, temperature and power-on history over time.
- CRC errors can indicate a cable or controller problem, while media, pending-sector and uncorrectable errors deserve immediate data protection.
- A saved smartctl report can be reviewed as read-only evidence without touching the original drive again.
Troubleshooting and uninstall
Why is no drive visible?
Confirm administrator or root access and check whether RAID, virtualization or a USB bridge hides the device. Record the connection path before changing hardware settings.
Why was the self-test interrupted?
Check sleep settings, USB power, cables and controller resets, save the current log and repeat only in a stable direct connection after protecting the data.
- Save the diagnostic recordExport the final report, test times and conclusion, associate it with the asset record and remove serial numbers from any public copy.
- Close and remove the applicationConfirm that no self-test is running, exit the interface and uninstall it through the platform; uninstalling does not repair a drive or replace a backup.
Frequently asked questions
Does PASSED mean the drive is completely safe?
No. It is one firmware signal and cannot rule out sudden failure, power issues, filesystem damage or deterioration below a threshold. Keep an independent backup.
Can an extended SMART test delete files?
A normal device self-test is a diagnostic operation, but it adds sustained I/O and runtime. When a unique data drive is already failing, recover data first instead of starting a long test.
Why does a USB drive show no SMART data?
Some bridges, enclosures and RAID controllers do not pass SMART commands or require a device-specific mode. Confirm hardware support rather than repeatedly writing to or opening the drive.
