How do I check the health of my hard drive?

Why is it important to check the health of your hard drive?

Hard drives are one of the most important components in your computer. They store all of your data including documents, photos, music, applications, and more. Over time, hard drives can start to fail or develop bad sectors that can lead to data loss or corruption. That’s why it’s critical to periodically check the health of your hard drives to identify any potential problems before they result in catastrophic data loss.

Some key reasons to check your hard drive health include:

  • Detect early signs of failure – By monitoring health metrics like SMART data, you can catch issues like bad sectors while the drive is still functioning. This gives you a chance to back up your data before failure.
  • Avoid unexpected crashes – No one wants their computer randomly crashing due to hard drive errors. Checking drive health lets you address problems proactively.
  • Prevent data loss – Hard drive problems can lead to irrecoverable data loss. Checking health allows you to identify these issues and backup data before it’s too late.
  • Identify performance issues – Factors like high temperature, fragmentation, or a cluttered drive can reduce performance. Checking health stats helps pinpoint these problems.
  • Determine if an upgrade is needed – Hard drive checks give you insight into the current condition of your drive. If it’s showing signs of age, it may be time for an upgrade.

In summary, keeping tabs on your hard drive health provides tremendous preventative maintenance benefits and ensures the safety of your precious data. Even if your computer seems fine, it’s wise to periodically examine key drive metrics.

How can I check hard drive health in Windows?

Windows provides several easy methods to analyze the current health status of your hard drives. Here are some top options:

Use the S.M.A.R.T. status check

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a monitoring system built into hard drives that detects and reports on various reliability indicators like temperature, errors, bad sectors, and more. Checking your drive’s S.M.A.R.T. status is one of the best ways to get overall health information.

To check S.M.A.R.T. data in Windows:

  1. Open the Start menu and search for “Command Prompt”
  2. Right-click Command Prompt and select “Run as administrator”
  3. In the Command Prompt window, type “wmic diskdrive get status” and hit Enter

This will display health information from S.M.A.R.T. about all physical drives in your system. Look for any drives listed as having a “Pred Fail” (Predictive Failure) status indicating issues that may lead to imminent failure.

Utilize the built-in Windows Disk Checking utility

All versions of Windows come with the Disk Checking utility (chkdsk) that can analyze drives and report issues like bad sectors, file system errors, and disk read/write problems.

To run chkdsk in Windows 10:

  1. Open File Explorer and right-click on the drive you want to scan
  2. Select “Properties” from the menu
  3. Click the “Tools” tab in the Properties window
  4. Under Error-Checking, click “Check” to launch chkdsk

The tool will scan the drive for any problems and provide a report on its condition. Running chkdsk periodically is a great way to detect early signs of trouble on a drive.

Check hard disk health with manufacturer tools

Most hard drive manufacturers provide their own drive monitoring and diagnostic utilities. For example, Seagate has SeaTools while Western Digital offers Data Lifeguard Diagnostics. These tools often provide even more in-depth health stats and testing capabilities tailored for those specific drive models.

Consult your drive maker’s website to download the appropriate version for your computer. Run their health check suite and it will thoroughly evaluate your drive status.

Monitor Health stats in Task Manager

Windows Task Manager now provides an easy way to view key hard disk health information:

  1. Press Ctrl+Shift+Esc to open Task Manager
  2. Click the “Performance” tab
  3. Scroll down to find the “Physical Disks” section

Here you can see read/write stats, current queue depth, average response times, and more. Spikes in queue length or response times can indicate issues with drive performance and health.

Use Third-Party Disk Monitoring Software

There are many excellent third party utilities available that provide expanded hard drive health monitoring and diagnostics. Popular options include:

  • CrystalDiskInfo – Provides clear status displays of drive health metrics like temperature, reallocated sectors, and lifespan.
  • Hard Disk Sentinel – Rates drive health on a simple 0-100 scale based on comprehensive analysis and predictive failure monitoring.
  • SSDlife Free – Great for monitoring solid state drive health and estimated lifetime remaining based on usage data.

These types of advanced tools are very useful for early detection of problems that built-in Windows utilities might miss. Most are free and easy to use as well.

How to check hard drive health on Mac

Mac users also have various utilities at their disposal to monitor hard drive health metrics and status:

Use First Aid in Disk Utility

Disk Utility is built into all Macs and includes a First Aid feature to check for disk errors and issues. To run it:

  1. Open Disk Utility (located in /Applications/Utilities)
  2. Select your physical hard drive device in the sidebar
  3. Click the “First Aid” tab
  4. Click “Run” to begin scanning the drive

First Aid will attempt to repair any issues found and report on any problems that require further attention. Run this regularly as preventative maintenance.

Check S.M.A.R.T. Status

MacOS also utilizes S.M.A.R.T. data to monitor drive health. To view this info:

  1. Open Disk Utility
  2. Click the drive you want to check
  3. Click the “S.M.A.R.T. Status” button near the top left

This will display a popup with all the S.M.A.R.T. health metrics being tracked by your drive. Monitor these closely for any signs of decline.

Use Drive Monitoring Tools

Helpful third-party drive utilities are also available for Mac:

  • Smartmontools – Open source app that provides detailed S.M.A.R.T analysis and drive health stats.
  • DriveDx – Advanced paid utility that monitors drives and predicts potential failures.
  • TechTool Pro – Full-featured suite for testing and tuning drive performance.

These kinds of specialized tools give you extra insight into your drive’s condition beyond what built-in Apple utilities provide.

What hard drive health stats should I monitor?

There are many technical metrics associated with analyzing hard drive health. But some key stats to keep an eye on include:

S.M.A.R.T. Errors and Warnings

The S.M.A.R.T. system tracks a variety of attributes like read/write errors, hardware ECC recovered, spin retry counts, and more. Any alerts or counts increasing in these fields indicates emerging drive issues.

Bad Sectors

Bad sectors are areas on the physical drive platters that can no longer reliably store data due to corruption or magnetic issues. Tools like chkdsk can detect these.

Current Pending Sectors

When a sector is marked bad, data gets re-written to a spare sector and the original is marked “pending” for reallocation. High pending sector counts signal problems.

Reallocated Sectors

This stat shows the total count of sectors that have been remapped from bad to spare ones. Drives can withstand some reallocation, but high counts indicate a failing drive.

Temperature

Excessive drive temps (above 50C) can degrade performance and lifespan. Good airflow is key to keeping your HDD cool. Solid state drives (SSDs) run cooler in general.

CRC Errors

CRC errors check the data written to your drive to ensure accuracy. High counts of CRC errors indicate potential data corruption issues.

Current Pending Operations

Task Manager tracks this queue of read/write operations waiting to complete. High pending queues lead to sluggish performance.

Read and Seek Errors

Problems occurring when drives attempt to access or read data means this key function is failing. Time for backup and replacement.

Monitoring these metrics gives you early warning of potential problems. Address any issues proactively before they lead to failure.

What action should I take if my hard drive shows signs of failure?

If your hard drive health checks reveal any indications of potential failure, it’s crucial to take prompt precautionary action:

1. Backup Your Data

The first priority is creating a complete backup of all your drive’s data in case it fully fails. Backup to an external drive, NAS, or cloud storage. Make sure your backup is easily restorable.

2. Cease Normal Usage

Halt any activities that write data to the ailing drive like file storage, program installs, downloads, etc. This prevents making the issues worse.

3. Try Drive Repair Software

Tools like Disk Utility First Aid on Mac or chkdsk on Windows may be able to fix some problems like file system corruption. This is worth trying.

4. Consider Data Recovery Services

If your drive is failing and you have important files at risk, a data recovery service could attempt restoration but it can be pricey.

5. Swap in a new hard drive

Ultimately, replacing the suspect drive with a new, healthy one will be required to permanently resolve the problem and secure your data.

Don’t take any chances – at the first signs of drive problems, take quick action to backup and preserve your precious data before things get worse.
