Using Windows’ Error Checking Tool

The simplest way to check an SD card for errors is by using the built-in Error Checking tool in Windows. Here’s how to use it:

  1. Insert the SD card into your Windows PC if not already inserted.
  2. Open File Explorer and right-click on the SD card drive.
  3. Select ‘Properties’ from the right-click menu.
  4. In the Properties window, click the ‘Tools’ tab.
  5. Under Error Checking, click ‘Check’. This will launch Check Disk.
  6. Check Disk will scan the drive for file system errors and bad sectors. Let it run to completion.
  7. If any errors are found, you’ll get the option to repair them. Do so to fix any issues.
  8. If Check Disk reports the disk is healthy, your SD card is likely in good shape.

The Error Checking scan is quick and straightforward. It checks the file system structure and scans for bad sectors which are physical defects on the SD card. This can identify any corruption or read/write issues.

Monitoring Performance

You can also check an SD card’s health by monitoring its performance over time. Windows has a built-in Performance Monitor that lets you see detailed storage metrics.

To use it to check SD card health:

  1. Open the Start menu and search for ‘Performance Monitor’. Open it.
  2. Click the green ‘+’ icon to add some performance counters.
  3. Add the ‘\PhysicalDisk(X)’ counters for Avg Disk Bytes/Read, Avg Disk Bytes/Write, and Disk Reads/sec.
  4. Replace (X) with your SD card drive letter.
  5. Click the play button to start monitoring.
  6. Watch the performance for your SD card. Consistent high latency or low speeds could indicate issues.
  7. Take note if speeds change drastically during different operations.

Performance Monitor lets you see detailed storage metrics in real-time. Watch for slow downs, inconsistent speeds, or low throughput which may indicate problems.

Checking SMART Data

Self-Monitoring, Analysis and Reporting Technology (SMART) is a system built into storage devices to monitor internal metrics like temperature, read errors, bad sectors, etc. Viewing the SMART data can give insight into an SD card’s health.

Here’s how to check SMART data on Windows:

  1. Open File Explorer and right-click the SD card drive.
  2. Select ‘Properties’ then click the ‘Tools’ tab.
  3. Under Error Checking, click ‘Check Now’ in the SMART status section.
  4. In the SMART window, click ‘Enable self-monitoring’.
  5. Click ‘Perform self-test’ to start a short or extended SMART test.
  6. Once complete, view the ‘Self-test log’ for any errors reported.
  7. Click the ‘Attributes’ tab to see metrics like read errors, bad blocks, etc.

Higher than normal read errors, high reallocation counts, and excessive bad blocks can indicate SD card problems. Monitor for changes over time.

Using Third-Party Diagnostics Software

For advanced diagnostics beyond Windows’ built-in tools, try third-party drive health utilities.

HDD Sentinel is one such utility that does in-depth drive analysis and health monitoring. Key features include:

  • Detailed drive health rating based on internal stats and tests.
  • Comprehensive SMART data and monitoring.
  • Ability to do drive benchmarks to test speeds.
  • S.M.A.R.T. Test to stress test the drive.
  • Short and extended drive self-tests.
  • Health and performance graphs over time.

For a more robust set of diagnostics tools, third-party software like HDD Sentinel can give you deeper insights into your SD card’s health.

Manual Health Checks

In addition to built-in tools, you can also perform some manual checks on your SD card to identify issues:

  • View Properties: This provides info like capacity and file system which can help identify issues.
  • Check for errors: Open files on the SD card to see if any open incorrectly or display errors.
  • Copy test files: Copy sample files to the card and then back to check for copy or corruption issues.
  • Read/write test: Time how long it takes to transfer files or folders to and from the card.

Doing manual file operations provides real-world testing to complement built-in disk diagnostics.

Understanding SD Card Health Status

When checking your SD card health, you may encounter various reports and indicators. Here are some key things to look for:

Error Checking

  • File system errors – Indicate corruption. May be repairable.
  • Bad sectors – Permanent physical defects on the card surface.
  • Read or write errors – Self-explanatory. Can cause data loss.
  • Read-only recommendation – Card should be replaced if advised.
  • No problems found – File system is intact and no bad sectors detected.

SMART Data

  • High read error count – Reliability concern and indicates defects.
  • High reallocation events – Bad sectors that have been remapped.
  • Excessive bad blocks – Permanent defects accumulating.
  • Temperature – Higher than normal may indicate issues.

Performance

  • Slow read/write speeds – Underperforming throughuput.
  • Sluggish operations – Latency introduced when transferring files.
  • Dropping transfer rates – Inconsistent performance.

External Factors

  • Card reader quality – May negatively impact speeds.
  • Full or fragmented drive – Reduced performance.
  • Card damage or wear – Obvious physical issues.

Troubleshooting Common SD Card Issues

If your SD card health check reveals problems, here are some tips for troubleshooting common issues:

SD Card Not Detected/Showing Up

  • Check if it is properly inserted in the card reader slot.
  • Try different reader ports if available.
  • Try the card in another device like a camera.
  • Check for any physical damage to card.
  • Update card reader drivers.
  • Clean card contacts gently with pencil eraser.

SD Card Read-Only/Write Protected

  • Slide write protection switch on card to off position if present.
  • The card itself may be damaged and write-locked.
  • Card reader may be write-protected. Check reader properties in Windows.
  • Try formatting – but will erase all data.

Slow SD Card Speeds

  • Cleanup space by removing files or formatting the card.
  • Use a higher quality card reader with optimal speeds.
  • Check if best performance mode enabled in card reader properties.
  • Test card speeds in a different device like a camera.
  • Update motherboard drivers and SD host controller drivers.

SD Card Errors/Corruption

  • Scan card for errors and attempt repair using Error Checking.
  • Back up data and reformat card to resolve file system issues.
  • Check if card works properly in another device.
  • Test card with badblocks to identify bad sectors.
  • Consider replacing card if physical defects are accumulating.

Debugging card problems will usually involve trying the card in a different reader and device, troubleshooting connections, inspecting physical condition, and testing with tools like Error Checking and badblocks.

When to Replace an SD Card

With routine checking and maintenance, SD cards can provide reliable performance for years. But there are certain signs that indicate a card should be replaced:

  • Read/write speeds have significantly deteriorated
  • Frequent write errors, corruption, or inability to write data
  • Substantial bad sectors reported by Error Checking or badblocks
  • Card has been in use for over 5 years
  • Card has been damaged by bending or water exposure
  • Card contacts are dirty, corroded or scratched

While SD cards can often be repaired with formatting or repartitioning, accumulating physical defects will eventually require replacement. Be sure to properly dispose of or destroy old cards.
