A corrupted SD card can be a real headache, especially when you suddenly can't open your photos, videos, or important files. Whether your SD card shows errors, becomes unreadable, or keeps asking you to format it, the good news is that you can often fix the problem by formatting it.
Can you format a corrupted SD card? Of course. In this guide, we'll show you how to format a corrupted SD card on Windows and Mac. Let's get your SD card back to working condition step by step.
If you're using a Windows PC, the following methods can help you format a corrupted SD card and restore it to normal.
File Explorer is the simplest way to format an SD card on Windows. It is suitable for SD cards with minor corruption or those that can still be recognized by the system. If the SD card appears under "This PC", you can format it directly through the right-click menu.
Here is how to format a corrupted SD card in a laptop using File Explorer:
Step 1. Insert the corrupted SD card into your laptop using an SD card slot or card reader, then open File Explorer by pressing "Windows" + "E".
Step 2. Click "This PC" from the left sidebar and locate your SD card under the "Devices and drives" section.
Step 3. Right-click the SD card, select "Format", and follow the on-screen instructions to complete the formatting process.
Step 4. Select the desired file system (FAT32, exFAT, or NTFS), and adjust the allocation unit size if needed.
Step 5. Uncheck the "Quick Format" option to perform a more thorough format.
Step 6. Click "Start" to begin formatting the corrupted SD card.
If File Explorer fails to format the SD card, you can try using Windows' built-in Disk Management tool instead. Here is how to format a corrupted SD card using Disk Management:
Step 1. Press "Windows" + "X", then select "Disk Management".
Step 2. Locate the SD card you want to format, right-click it, and select the "Format" option.
Step 3. Choose the desired file system, enable the "Perform a Quick Format" option, and click "OK" to start the process.
When an SD card cannot be formatted using regular methods, you can use the DiskPart tool instead. However, this method requires caution. Selecting the wrong disk number may cause data on other drives to be erased.
Here is how to format a corrupted SD card in CMD:
Step 1. Press "Windows" + "R" to open the Run dialog box, type "cmd", and click "OK" to launch Command Prompt.
Step 2. Type "Diskpart" and press "Enter". Then enter "list disk" to display all available disks on your computer.
Step 3. Identify your corrupted SD card, type "select disk (X)", and press "Enter" to select the target disk.
Step 4. Enter the "clean" command and press "Enter" to remove all data and partitions from the SD card.
Step 5. Type "create partition primary" to create a new partition, then enter "fs=fat32" to format the SD card with the FAT32 file system.
Step 6. Type "assign letter (X)" and press "Enter" to assign a drive letter, allowing Windows to access the formatted SD card.
