How Can I Check Raspberry Pi SD Card Health

According to some research, SD cards don't seem to reveal their health condition as SSDs do. However, I would like to be able to identify problems before there is a noticeable drop in performance. What are the best ways to monitor the condition of an SD card and identify issues before they become serious?

To ensure the durability of your Raspberry Pi SD card, it's crucial to check it regularly. Once a month is recommended. I will discuss two practical methods to monitor the SD card health on Raspberry Pi, including free third-party software and a Windows built-in tool.

Note: Before running the Raspberry Pi SD Card health check, users should clone the SD card to back up valuable data.

Way 1. Automatically Monitor the Raspberry Pi SD Card Health

EaseUS Partition Master Free is a versatile software that allows users to gain in-depth insights into SD card health. Using its "Disk Health" feature, you can check and repair SD card errors:

Step 1. Connect the Raspberry Pi SD card to your computer.

Step 2. Launch EaseUS Partition Master and download and activate the "Disk Health" tool in the "Discovery" tab.

Step 3. Select the target Raspberry Pi SD card and hit the "Refresh" option. Then, you can view the health condition of your SD card.

Way 2. Check Raspberry Pi SD Card Health Using fsck Command

Step 1. Open your Raspberry Pi's Terminal. Enter sudo umount /dev/mmcblk0p2 and click Enter after typing the command. This command unmounts the root file system partition, normally found on the second SD card partition.

Step 2. To execute the command, type sudo fsck /dev/mmcblk0p2 and hit Enter. The root file system partition is subjected to a fsck operation, and the output is shown. Fsck will notify you to make corrections if it finds any mistakes or problems. To verify, type y and hit Enter.
