Method #3: How to Back Up a Corrupted SD Card Before Formatting?

An SD card can get corrupted or damaged for some reason, for example, it becomes inaccessible and asks you to format it each time you try to open it. What does the issue mean? With an corrupted SD card, you cannot access files directly. Although formatting can fix corrupted SD cards in many situations, it will erase all files. Nobody wants to format the SD card before everything gets backed up. It will surely be a devastating thing if you lose valuable data such as family photo, working files, videos, learning materials, etc. Don't lost hope, you still have chance to backup files from a corrupted SD card before formatting it.

Here are steps to retrieve files from a corrupted SD card and safely export files to a hard drive:

Step 1. First go ahead to free download and install DiskGenius Professional Edition on your computer and then launch it. Insert the SD card on your computer and you can view it from the disk list on the left pane of the program.

Step 2. Right-click the corrupted SD card and choose "Recover Lost Files".

This feature can read and scan memory cards that are not readable or accessible by computer, and then identify files including those had been lost from the drive. Even though the SD card cannot be accessed by your camara, laptop, cellphone, or tablet, you can start the scanning without formatting the memory card.

Step 3. Click "Start" button to scan the memory card.

The default scanning settings will perform a thorough, deep and complete scanning, which gives the best chance of finding out as many files as possible. If you want to specify file type for the deep scanning, then click "Select File Type" (By default, all file types are selected).

Step 4. Wait for the scanning to complete.

Step 5. View lost files to check if they are still recoverable.

View files found by the scanning process and locate files you want to restore. Files are displayed like what Windows File Explorer does: the file structure center is placed on the left-hand side, and files and folders inside the selected directory are listed on the right-hard side.

Other Methods to Backup an SD Card

Manually Copy and Paste SD Card Data in Windows 11/10/8/7

It seems that copying and pasting does not relate to any technical skills, and yet it is strongly recommended when you just want to backup a small amount of data for your SD cards, hard disks, external hard drives, USB flash drives and so on. To backup SD card data, follow steps below:

Step 1. Connect the SD card you want to backup to your computer. The connection can be done with the help of a card reader. A 3.0 USB card reader can be a better choice, for it is faster to transfer data.

Step 2. Open Windows File Explorer on your computer and open the SD card.

Step 3. Select files and folders you want to backup and press "CTRL + C" to copy data.

Step 4. Open the destination location on your hard drive or other device and press "CTRL + V".

The data pasting process may take a while depending on the size of data you've copied. Do not remove the SD card before process is complete.

Backup SD Card Data by Uploading to Cloud Drives

Cloud storage is an excellent place to backup files when there is not sufficient space on your physical drives or you want to access files while you are not at home. Speaking of cloud drives, there are many options available, for example, Google Drive, Microsoft One Drive, Dropbox, iCloud, pCloud, etc. To upload SD card data to cloud drives, you need to make sure:

  • The device where the SD card is inserted should properly connect to the Internet which provides fast data uploading speed.
  • Make sure the cloud drive has enough free space. The could space is relatively cost-effective compared to buying physical hard drives. Choose a proper plan based on your needs.
  • Set a strong password for your cloud drive to prevent hackers from breaking into your account.

Use your Smartphone or Tablet

This method can be used when no computer is at hand. Copy and backup photos from SD card to your smartphone or tablet can be done by using the OTG feature. USB OTG (on-the-go) is a standard protocol that allows devices to read data from a USB device without the need of connecting them to a PC. Most Android phones come with a micro-USB or USB-C port instead of a USB port, so we need a OTG adaptor to connect the Android phone and the SD card which is put into a card reader. After connecting the SD card to your smartphone, you can start transferring data.

Clone SD Cards in Digital Camera

This backup method is workable when your digital camera has dual memory card slots. By putting two memory cards into a camera, you can choose RAW photos on one card and JPG files to the other, take photos and record them on both memory cards simultaneously, or use one of the memory cards to provide extra space.

Hence, if your camera supports to place two memory cards, you can make use of this feature to backup data when a computer is not available.

Use Raspberry Pi to Backup SD Card

Raspberry Pi is a series of small single-board computers that allows users of all ages to explore a wide range of computer programming skills. You can install operating systems like Debian-based Linux distribution, Windows 10 IoT Core, Ubuntu, etc. Set up the device and install a proper operating system, and then you can use it to backup data or fulfill other tasks.

Conclusion

Backing up SD cards can be done via various methods even when there is not a computer. No matter what backup method or backup software you use, be sure to backup files timely and regularly, which is the best way to protect data. In addition to data backup, you can also learn another skill for data protection, i.e. data recovery which can get back deleted or lost files easily.
