How to Format a Corrupted SD Card on Android

Dealing with a corrupted SD card can be frustrating, especially if your Android device is unable to recognize it anymore. However, with the right steps, your corrupt SD card might be brought back to life. This article will guide you through the process of formatting a corrupted SD card, from on-device solutions to desktop user interfaces.

Initial Attempts to Formatting

Before starting any more advanced actions, it's worth trying some simple methods to see if your corrupt SD card can be recognized:

Cleaning the SD card: Dust and debris can sometimes cause a card to become corrupted. Gently clean the surface of the SD card with an eraser. Don't use any harsh chemicals or abrasive materials, as they can damage the card. SD card in a reader: If cleaning doesn't work, try putting the SD card in a card reader connected to a computer. If the computer recognizes the card, you can attempt to format it from there.

Using Your Android Phone

Many modern Android phones have the capability to reformat an SD card. Here’s how to do it:

Check if your phone can recognize the card: Bring your phone into a trusted Android device to check if it can read the SD card. Most Android phones will automatically display a notification asking if you want to format the card when they detect a corrupted one. Allow the formatting process: If your phone does offer the option to format the SD card, follow the prompts to complete the process. This may involve confirming the device is unlocked, allowing factory reset, and confirming the deletion of any data on the SD card. Another attempt: After the formatting is complete, try to open the files again or insert the card into another device.

While these methods often work for simple corruption issues, it's important to understand that sometimes the corruption is more severe.

Professional Formatting with a Computer

If your SD card still isn't recognized or the phone cannot format it, you may need to use a more advanced method:

Get an SD card adapter: You will need an SD card adapter to connect the SD card to your computer. SD cards are not typically recognized directly by most computer ports. Insert the card into the adapter: Insert the SD card into the adapter and connect the adapter to your computer using the appropriate USB cable. Download and install the formatting tool: Download a tool like Data Decompiled USB or SDCardTools from a reputable source. Follow the instructions for your specific tool to format the SD card. Format the SD card: Run the formatting tool and follow the on-screen instructions to format the SD card. This process can take a while and may require you to confirm the deletion of all data on the card.

Once the format is complete, try to insert the card back into your Android device or another device to see if it works properly.

Understanding the Nature of Corruption

It's important to note that corruption in SD cards isn't always fixable. Corruption often means the hardware is failing, and in the last few years, counterfeit SD cards have become more common. If you've tried all the methods above and your SD card is still not recognized, it might be time to consider a replacement card.
