How to Test Your Hard Drive Health: Windows, Mac OS, Linux

Use CHKDSK (Check Disk Utility)

CHKDSK is a built-in Windows tool that scans drives for file system errors and bad sectors, automatically repairing any issues it finds. It is reliable, does not require additional software, and helps maintain hard drive performance and reliability. TechWaste Recycling recommends using CHKDSK regularly to prevent data loss and ensure smooth system operation.

Steps to use CHKDSK on Windows:

Open Command Prompt as Administrator:

Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator. This ensures you have the necessary permissions to scan and repair system drives.

Run CHKDSK with repair commands:

Type chkdsk C: /f /r and press Enter. Replace C: with the drive letter you want to check. The /f flag fixes errors automatically, and /r locates bad sectors and recovers readable information.

Schedule a scan for system drives:

The drive is in use; Windows will prompt you to schedule the scan at the next restart. Type Y and press Enter. This allows CHKDSK to scan system files that are otherwise locked during regular operation.

Restart your computer:

Upon restarting, CHKDSK will run before Windows loads. It will check the drive sector by sector, repairing errors and marking bad sectors as unusable. The time required depends on the drive size and the number of errors that occur.

Review the results:

After Windows loads, open the Command Prompt again and review the scan summary. It displays fixed file system errors, the number of bad sectors detected, and the total disk space recovered. This provides a clear picture of driving health.

CHKDSK provides the most detailed repair and error correction, but it takes longer, especially on large drives. Windows SMART Status Check is faster and alerts users to potential hardware failures early, but it does not repair errors. Disk Management provides a visual overview of partitions and free space, making it very user-friendly; however, it cannot correct mistakes that have already occurred. The Windows Error Checking Tool is simple and suitable for casual users, but it offers less detail than CHKDSK. PowerShell SMART checks provide in-depth metrics and can be automated, but require command-line knowledge. Choosing the correct method depends on whether you prioritize speed, detail, or ease of use, with CHKDSK being ideal for thorough maintenance.

Use Windows SMART Status Check

Windows SMART Status Check uses the drive’s built-in Self-Monitoring, Analysis, and Reporting Technology to provide early warnings of potential drive failures. It is fast, reliable, and helps identify issues before they affect performance. TechWaste Recycling recommends using SMART status checks regularly to maintain system reliability and prevent data loss.

Steps to use Windows SMART Status Check:

Open Command Prompt as Administrator:

Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator. This ensures full access to drive status information. Running as an administrator is required because regular users cannot access SMART data for system drives.

Run SMART status command:

Type “wmic diskdrive get status” and press Enter. Windows will list each connected drive along with its SMART status. This quick command gives a simple “OK” or warning for each drive without additional setup.

Interpret the results:

A status of “OK” indicates the drive is healthy and operating normally. “Pred Fail” or any warning suggests the drive may fail soon and requires immediate backup or replacement. SMART warnings enable users to take action before a drive failure actually occurs.

Check detailed SMART attributes (optional):

Use third-party tools like CrystalDiskInfo or Hard Disk Sentinel to view in-depth metrics such as reallocated sectors, spin retry count, temperature, read/write error rates, and overall health percentage. These details help identify early signs of wear or potential failure that basic status may miss.

Schedule regular checks:

Running SMART status checks on a weekly or monthly basis allows for the early detection of mechanical or electronic issues. Frequent checks help maintain system stability and prevent unexpected data loss over time.

The SMART Status Check is faster and more convenient than CHKDSK, as it does not require a system restart. It is ideal for preventive monitoring rather than repair. It provides early warnings of hardware failure but does not repair errors, unlike the CHKDSK utility. Disk Management offers a visual overview and is very user-friendly, but lacks detailed health metrics. The Windows Error Checking Tool is simple but slower and less informative for large drives. PowerShell SMART checks or third-party tools provide the most detailed data, but they require technical knowledge. Overall, SMART Status Check is best for quick diagnostics, while CHKDSK is preferred for thorough error correction and repair.

Use Disk Management

Disk Management is a built-in Windows tool that provides a visual overview of all connected drives, partitions, and their status. It helps users identify inaccessible drives, check free space, and perform basic drive operations. TechWaste Recycling recommends using Disk Management regularly to monitor drive structure and detect early signs of potential issues.

Steps to use Disk Management on Windows:

Open Disk Management:

Press Windows + X and select Disk Management from the menu, or press Windows + R, type diskmgmt.msc, and press Enter. This opens a graphical interface showing all internal and external drives.

Review drive and partition status:

Check each drive for labels such as Healthy, RAW, or Unallocated. Healthy drives are functioning correctly, while warnings or errors indicate potential issues.

Examine free space and usage:

Look at the size, capacity, and free space of each partition. Low free space impact performance may be required, necessitating cleanup or resizing of the storage space.

Identify problematic drives:

Drives marked as Unallocated or not initialized may need further action, such as formatting or running CHKDSK. This step helps prevent data loss by alerting users to drives that are inaccessible or improperly configured.

Perform basic drive tasks (optional):

You create new partitions, extend or shrink existing ones, or change drive letters. These operations help organize data and optimize storage allocation without the need for third-party tools.

Disk Management is highly user-friendly and provides a clear visual overview, making it ideal for casual users and those unfamiliar with command-line tools. It is faster for checking the drive structure than CHKDSK, but it cannot repair errors or scan for bad sectors. SMART Status Check provides early warnings of hardware failure, but is less visually intuitive. CHKDSK offers the most thorough repair and error correction, while PowerShell SMART checks provide detailed metrics for advanced users. Overall, Disk Management is best suited for a quick overview and partition management, while CHKDSK and SMART checks are more suitable for in-depth diagnostics and preventive maintenance.

Use Windows Error Checking Tool

The Windows Error Checking Tool scans drives for file system errors and minor corruption, helping maintain hard drive health. It is simple, user-friendly, and suitable for casual users who want to ensure drive integrity without command-line tools.

Start the scan:

Check for file system errors by clicking Scan drive. The tool scans for corrupted files, bad sectors, and other minor performance problems. This automatically analyses the drive for risk.

Review results and repair:

Windows displays results after the scan and suggests fixing the found problems. You repair errors automatically or review them before taking action to ensure safe maintenance and prevent accidental data loss.

Schedule follow-up checks:

Repeat scans periodically to maintain drive health and prevent minor errors from escalating into major problems. Regular scanning helps maintain optimal system performance, extends the lifespan of drives, and ensures data integrity over time.

The Error Checking Tool is faster and more user-friendly than CHKDSK or PowerShell SMART checks, making it ideal for casual users. It provides a basic scan for file system errors but is less detailed than CHKDSK or SMART checks, and cannot detect early hardware failure. Disk Management visualizes partitions but does not detect file corruption. SMART Status Check warns of possible hardware problems, but not repair errors. Overall, the Error Checking Tool is suitable for routine maintenance and quick Error detection, whereas CHKDSK and SMART checks are suitable for detailed diagnostics and preventive monitoring.

Check SMART Status Using PowerShell.

PowerShell enables advanced users to inspect SMART (Self-Monitoring, Analysis, and Reporting Technology) data for all connected drives, providing insights into drive health and potential failure metrics. This method provides more detailed information than standard Windows tools and is recommended by TechWaste Recycling for proactive hard drive monitoring.

Steps to use PowerShell SMART Status Check on Windows:

Open PowerShell as Administrator:

Press Windows + S, type PowerShell, right-click Windows PowerShell, and select Run as administrator. Administrator access is required to retrieve SMART data from system drives.

Run SMART query command:

Type Get-PhysicalDisk | Select-Object FriendlyName, Operational Status, Health Status, and press Enter. This command lists all drives, along with their operational and health statuses, in a structured format.

Interpret the results:

The Health Status column shows Healthy, Warning, or Unhealthy values. Healthy means no problems found, Warning means possible issues, and Unhealthy means imminent failure with backup or replacement.

Check detailed SMART attributes (optional):

For more detailed metrics like predictive failure flags, type Get-WmiObject-Namespace rootwmi-Class MSStorageDriver _ FailurePredictStatus. This provides low-level information on mechanical and electronic health indicators, enabling early detection of failures.

Schedule automated monitoring (optional):

Create a PowerShell script to run these checks and log results periodically. Automatic checking ensures regular monitoring without human intervention to avoid unexpected drive failures.

PowerShell SMART checks return the most detailed drive health metrics for advanced users or IT professionals. It supports automation and logging that the Error Checking Tool or Disk Management cannot. But it is less intuitive for casual users than graphical tools. CHKDSK performs extensive error repair but takes longer and sometimes requires a system restart. The SMART Status Check via Command Prompt is quicker and simpler, but it provides less detail. Generally speaking, PowerShell SMART checks are suited for detailed diagnostics and proactive monitoring, whereas speed, ease of use, or repair are preferred elsewhere.

How to Check Hard Drive Health on MacOS?

Mac OS offers multiple methods for monitoring and maintaining hard drive health, ensuring optimal performance and preventing data loss.

The following points show how to check hard drive health on MacOS:

• Disk Utility

It is the primary built-in tool for checking drives. By opening Disk Utility from Applications > Utilities, selecting the drive, and running First Aid, macOS scans for file system errors, bad sectors, and minor corruption, repairing issues automatically to maintain smooth operation. TechWaste Recycling recommends using Disk Utility regularly for consistent drive maintenance.

• SMART Status in Disk Utility

It provides a quick overview of a driver’s condition. Selecting a drive in Disk Utility displays the SMART Status as “Verified” for healthy drives or “Failing” if there are potential problems. Using this method reveals early hardware issues and provides users with a fast and reliable indication of possible failures before they impact performance.

• Terminal

This is an advanced technique for users requiring detailed diagnostics. Terminal generates a report of errors and inconsistencies by using commands such as diskutil list to identify drives and diskutil verify / dev / disk0 to scan them. This technical method gives insights beyond the visual checks of Disk Utility and is intended for advanced users or those who understand its pros.

How to Check Hard Drive Health on Linux?

To check hard drive health on Linux, several tools are available depending on your distribution and technical preference. Popular methods include fsck (File System Consistency Check), SMART Tools, Disk Utility (on Ubuntu and other GNOME-based distributions), and badblocks. These methods allow users to verify file system integrity, monitor drive health, and detect bad sectors.

The following points show how to check hard drive health on Linux:

• Use fsck (File System Consistency Check):

Open the Terminal and type sudo fsck/dev / sdX (where sdX is the drive identifier). This command checks for inconsistencies, repairs minor corruption, and verifies the file system structure. For precise detection of file system errors, fsck must be run on an unmounted file system. This may mean booting from a live USB for the root drive.

• Use SMART Tools:

Install smartmontools via your package manager (sudo apt install smartmontools). Run sudo smartctl-a / dev / sdX to see the SMART attributes of the drive. It contains technical information about the reallocated sectors, temperature, and predicted failure probabilities. SMART Tools offer comprehensive insights, but they require experience in interpreting technical metrics.

• Use Disk Utility (GNOME-based distributions):

Open Disks from the application menu, select the drive, and click SMART Data & Self-Tests. This graphical tool allows you to check drive health and run short or long self-tests quickly. It is user-friendly and provides visual indicators, but may not show all low-level SMART attributes.

• Using badblocks:

In the Terminal, type sudo badblocks -v /dev/sdX to scan the drive for bad sectors. Badblocks performs a detailed surface scan and reports damaged blocks. It helps detect physical issues with the drive, but it is time-consuming and does not automatically repair errors.

Use fsck (File System Consistency Check)

Open Terminal:

Access the Terminal on your Linux system. Administrator privileges are required because disk-level checks and repairs need elevated permissions. Terminal provides direct control over file system utilities, making it more precise than graphical tools.

Unmount the drive:

Before running fsck, unmount the drive using sudo umount /dev/sdX (replace sdX with the correct drive identifier). Unmounting prevents data corruption and ensures that the file system is not actively in use during the scan. For root drives, booting from a live USB may be necessary.

Run the fsck command:

Type sudo fsck /dev/sdX and press Enter. Fsck scans the file system thoroughly, checking for inconsistencies, corrupted files, and structural errors. It will also detect missing or damaged metadata that affects drive performance.

Review and repair:

Fsck prompts the user to approve repairs for any detected issues. Type y to allow the tool to fix them. The process takes several minutes for small drives and significantly longer for large or heavily used drives. After completion, the Terminal will display a summary report of all actions performed.

Fsck is a highly reliable tool for detecting and repairing file system errors, ensuring data integrity and stable drive performance. It offers detailed diagnostics that are not available in simple graphical utilities. However, it is less user-friendly, requires unmounting the drive or booting from a live environment for root drives, and does not detect hardware-level failures such as bad sectors, which SMART Tools or badblocks identify.

Use SMART Tools

Install smartmontools:

Type sudo apt install smartmontools for Ubuntu/Debian or the equivalent command for your Linux distribution in the Terminal. This installs utilities to access and monitor SMART data on drives.

Identify the drive:

You list connected drives with lsblk or sudo fdisk-l. Use the correct drive identifier/dev / sda for monitoring purposes.

Run SMART Check:

Just type sudo smartctl-a / dev / sda and hit Enter. The following command reads all SMART attributes of the drive, including temperature, reallocated sectors, read/write errors, and predicted failure rates.

Analyze the results:

Review the detailed report carefully. Key metrics, such as Reallocated_Sector_Ct, Current_Pending_Sector, and Temperature_Celsius, indicate the health and reliability of the drive. Alerts on these attributes suggest potential failure.

Perform self-tests (optional):

You run a short test with sudo smartctl -t short /dev/sda or an extended test with sudo smartctl -t long /dev/sda. Short tests are quick, while long tests provide a more thorough check of drive health.

SMART Tools provide low-level diagnostics and predictive monitoring for technical users who require in-depth insights into drive health. They detect potential failures very accurately. SMART Tools are less intuitive, require technical knowledge to interpret metrics, and do not correct errors automatically.

Use Disk Utility (on Ubuntu and other distributions with GNOME)

Open Disk Utility:

Search for Disks in the application menu and launch it. This built-in graphical tool enables users to quickly inspect and manage all connected drives without requiring the use of the Terminal.

Select the drive:

Click the drive you want to check from the sidebar. Selecting the correct drive ensures accurate health monitoring and prevents accidental checks on other disks.

View SMART data:

Select SMART Data and Self-Tests from the menu or gear icon. It displays key indicators, including temperature, error counts, and reallocated sectors.

Run self-tests:

Pick a short/extended self-test. While the short test checks critical sectors in a few minutes, the extended test scans the whole drive for deeper problems, including the bad sectors that affect performance.

Analyze results:

Check the results for any warnings or failure messages. The tool labels drives as Healthy, Warning, or Failing, giving an easy-to-understand overview of drive status and helping users decide if maintenance or replacement is needed.

Disk Utility features a user-friendly visual interface that is easy for beginners to understand. This is quicker than the command-line tools and provides immediate SMART status. It offers less technical information than SMART Tools or fsck, and cannot repair file system errors. Thus, it is used in conjunction with other diagnostic tools to assess drive health.

Using badblocks

Open Terminal:

Access the Terminal on your Linux system. Administrator privileges are required because badblocks performs a low-level scan directly on the disk.

Identify the drive:

Type lsblk or sudo fdisk -l to list all connected drives and note the correct drive identifier (e.g., /dev/sda). This ensures you are scanning the proper drive.

Run badblocks scan:

Press Enter to type sudo badblocks-v / dev / sda. The -v flag allows verbose output showing each block being checked as it is processed. Badblocks will look for damaged or unreadable sectors on the disk.

Analyze results:

After completion, badblocks displays a list of all detected bad sectors. Drives with bad blocks may experience performance problems, data corruption, or future failures.

Optional write-mode scan:

For a more thorough check, you use sudo badblocks -w /dev/sda, which writes patterns to each block. This will erase all data on the drive, so it is essential to have backups before using this mode.

Badblocks provides a highly detailed scan and detects physical disk issues that other tools may miss. It is ideal for diagnosing potential hardware failures. However, it is slower than other methods, less user-friendly due to the command-line interface, and requires technical knowledge. Unlike Disk Utility, it cannot provide a simple visual summary; therefore, it is best used in conjunction with SMART Tools or fsck for comprehensive health monitoring.
