How to fix a damaged Memory SD Card / Hard Disk / USB disk.

Recently the micro SD card (external memory card) on my Samsung S4 mobile phone becomes damaged and the phone freezes when trying to read contents on SD card or displays a message that says that the card needs to be formatted (SD card is damaged. Try reformatting it ). 

In my case I didn’t format the card, because I have many important photos on it, so I decided to connect the SD card on my Windows 7 computer and view the SD card’s contents from there. In Windows the SD card is recognized properly as a “Removable device” under “My Computer”, but unfortunately is unreadable when trying to access it’s contents and the system prompts to format the device (SD card).

As my last chance, I decided to go a step further in order to fix the corrupted SD card and recover my files. Finally after some hours, was able to retrieve many of my photos from the SD card, so I wrote this guide to help others with the same problem.

In this tutorial you can find detailed instructions on how to repair a damaged/corrupted/unreadable hard disk or memory card (microSD, miniSD, XD, etc.) and retrieve your files.

 

How to repair a corrupted disk (HDD, USB Disk, Memory Card).

Method 1. Use Check Disk to repair the corrupted disk.

– Run Check Disk command (from an elevated command prompt) to find and repair the damaged SD memory card. To do that:

1. From Windows Explorer, note the Drive Letter assigned to your SD card/Removable Device (e.g. “E”)

2. Open Command Prompt with Administrative privileges. To do that:

  • In Windows 7: Navigate to Start –> Programs –> Accessories. Then, right click at Command Prompt and select Run as Administrator
  • In Windows 8 or 10: Right click on Start menu (Windows Flag) and select Command Prompt (Admin).

3. In command prompt window type the following command and press Enter: *
