How to Recover Data from Corrupted SD Card

If you’re facing data corruption on your SD card, don’t worry, there are easy and free methods to recover your files. Here’s what you can do:

1. Connect your SD card to a computer using a card reader or adapter.
2. On Windows, press Windows key + R to open the Run command. Type “cmd” and hit Enter to open the Command Prompt.
3. In the Command Prompt, type “chkdsk /f [drive letter]:” (replace [drive letter] with the letter assigned to your SD card) and press Enter. This will repair any file system errors.
4. If the above method doesn’t work, try using a reliable SD card repair tool like Sandisk RescuePro or Disk Drill.
5. On a Mac, you can use the built-in Disk Utility to repair the corrupted SD card. Go to Applications > Utilities > Disk Utility, select the SD card, and click on the “First Aid” tab.

python
import pyudev
import subprocess

def find_corrupted_sd_cards():
context = pyudev.Context()
devices = context.list_devices(subsystem='block', ID_BUS='usb')

corrupted_sd_cards = []

for device in devices:
try:
output = subprocess.check_output(['fsck', '-nv', device.device_node])
if b"Filesystem modified" in output:
corrupted_sd_cards.append(device.device_node)
except subprocess.CalledProcessError:
pass

return corrupted_sd_cards

def recover_data_from_sd_card(sd_card_path):
# Add your custom recovery logic here
pass

# Example usage
corrupted_sd_cards = find_corrupted_sd_cards()

if len(corrupted_sd_cards) > 0:
print("Corrupted SD card(s) detected:")
for sd_card_path in corrupted_sd_cards:
print(sd_card_path)
recover_data_from_sd_card(sd_card_path)
else:
print("No corrupted SD cards found.")

Please note that this code snippet only demonstrates how you can identify potentially corrupted SD cards connected via USB. The `find_corrupted_sd_cards` function uses the `fsck` command-line tool to check for file system modifications. The `recover_data_from_sd_card` function is a placeholder where you can add your own custom recovery logic based on your specific requirements.
