Are there tools to check the health of an SD/MicroSD card? Yes, there are several tools available to check the health of your SD or MicroSD card. Here are some commonly used ones: 1. **H2Testw**: This is a free Windows application that can test the read and write speeds of an SD card and detect any bad sectors. 2. **CrystalDiskInfo**: This software supports not only hard drives but also SD and MicroSD cards, displaying detailed information about the card's health status and temperature. 3. **SD Card Formatter**: Provided by the SD Association, this tool not only formats SD cards but also checks their health. 4. **CardRecovery**: Primarily a data recovery tool, it can also assess the health of an SD card during the scanning process. 5. **Linux Command Line Tools**: If you're using Linux, you can use `fsck` to check for file system errors or `dd` for bad block detection. Make sure to back up important data before using these tools, as some tests may overwrite or delete existing content. Choose the appropriate tool based on your operating system and requirements.
SD and microSD cards are small enough to be used in many small devices, yet have capacities large enough to hold a lot of pixel-rich data, which explains their popularity.
Many users care about the health of their SD cards and wonder if there is a tool to check SD card health on Windows, Mac, or Android. Well, the fact is that unlike SSDs, SD cards don't have SMART, which stands for Self-Monitoring, Analysis, and Reporting Technology. First of all, monitoring the health of an SD card is not a critical function for its use, so there's no specific interface included for a health test.
As such, you don't need to check the health of your SD/microSD card. If you want to gauge its performance, you can test its file system, bad sectors, or read/write speed instead. Here are some popular benchmarking tools:
- H2testw: Available for Windows only
- AI SD Bench: For Android devices
- Blackmagic Disk Speed Test: For MacOS

Especially if the speed class doesn't match the advertised performance, you should be suspicious that you might have a fake SD/microSD card on your hands.
However, if you want to check all potentially important aspects, such as the health of your SD card, bad sectors, file system errors, and read-write speed, the above tools won't cut it. Here, we recommend using the more reliable “Partition Master,” and we'll see how it can help us.
Check the status of your SD/MicroSD card via the tool Partition Master
With AOMEI Partition Assistant Professional, you can locate bad sectors on the SD card, check file system errors on the SD card, and test the SD card speed. With its help, you can thoroughly examine the status of the SD card. Plus, it has great compatibility and runs well on all Windows versions. Additionally, it's user-friendly; the clear interface and timely prompts make the checking process smooth.
The longer an SD card is used, the more likely it is that errors, bad sectors, or damage will occur. To check the health of your SD card, Partition Master can help by:
We will provide a detailed guide to each of these elements in turn.
Guideline 1: Check for file system errors
Guideline 2: Locate bad sectors
Step1: Launch Partition Assistant, right click the hard drive you want to check and then choose “Surface Test”.
The operation is performed immediately, and any bad sectors are marked in red.
? Guide 3: Testing SD Card Speeds
Step 1: Launch AOMEI Partition Assistant. Then click the Download button to activate the "DiskMark" feature in the "Discovery" area.
Step 2: Select the target drive, test data, and block size from the drop-down menus.
Step 3. Once all settings are configured, click on the “Start” button to begin the disk test. You will then see data such as sequential or random read/write speeds, I/O operations, and latency.
The steps are the same if you want to run an microSD card speed test.
Main features of Partition Master:
Now that you've learned how to use this tool to check for SD card errors, let's look at some of its other features:
- Clone an SD card
- Perform a disk surface test
- Repair bad sectors on an SD card
- Check SSD health and test its speed
- Format an SD card on Windows 10/11
To better manage your SD card, don't miss this tool. Download it and give it a try.
The bottom line?
Unhealthy or fake SD cards will eventually lead to errors like “SD card not formatted,” “card not recognized,” “SD card read write error,” “attempt to repair failed,” “cannot format,” “SD card shows 0 bytes,” “SD card inaccessible,” or “the volume does not contain a recognizable file system.” Then, over time, timely checking and repairing the file system of the SD card can effectively prevent these errors. The tool Partition Master is a great one for this purpose. Now you can share this tool so that more people can get to know it.
Frequently Asked Questions about Tools to Check SD/MicroSD Card Health
As mentioned, SD or microSD cards don't use SMART technology, so you can't check their health with specific tools. However, you can analyze their condition by looking for file system errors and testing read and write speeds. Here are some questions to help evaluate the situation:

There's really no need to check the health of your SD card, but if you want to test the remaining space and read/write speeds of your storage medium, Partition Master is a good choice. It can help you test the speed of your SD or MicroSD card, scan and fix bad sectors, and other file system errors on the SD card.
**How to Check the Health of an SD Card on Android?** To check the health of an SD card on your Android device, try these methods: 1. **Using the Built-in Storage Info App**: - Open your phone's "Settings." - Scroll and tap "Storage" or "Storage & USB." - Here, you can see detailed information about the SD card, like total capacity, used space, and available space. While this doesn't directly indicate health, unusual usage patterns might suggest issues. 2. **Using Third-Party Apps**: - Download and install an SD card health check app, such as "SD Card Analyzer" or "Sd Card Health Check." - Run the app, which will scan the SD card and provide information about its health, number of errors, and performance. 3. **Checking via Computer**: - Connect the SD card to a computer. - Use a file manager to inspect the SD card's contents for corrupted or unreadable files. - Run a disk checking tool, like "Disk Error Checking" in Windows or "Disk Utility" in macOS, to scan and fix errors. 4. **Observing Unusual Behavior**: - Notice if the SD card frequently exhibits errors, such as missing photos, app crashes, or inaccessible files. - Slow performance or frequent formatting requests may also signal a health issue. Keep in mind that if the SD card has severe problems, it might be necessary to replace it to ensure data safety.
An SD card stores files, documents, pictures, and other important data, so losing that information can be a nightmare. However, by using an SD card health-checking app for Android, you can get a sense of the condition of your memory card. You can download apps like SD Insight, Fake Sdcard Checker, or Fake Device Test to run speed tests on your phone, as directed. If it's running too slow, that could indicate bad sectors or other issues affecting its health.
3. What is H2testw?
While H2testw is a powerful tool that can test SD cards and USB flash drives for existing issues and detect fake SD cards and USB flash drives, it can take hours or even days to scan newer high-capacity SD cards or drives. Overall, though, it's a safe and reliable speed testing tool. If you want to ensure your speed testing process remains safe and effective, Partition Master is a better choice.
