Why clone the SD card to a larger card?

In general, several common reasons account for the behavior of cloning SD cards in all Windows systems, like cloning Raspberry Pi SD cards to larger cards. See if you’re in one of those situations.

  • Not enough space to store data. You may be told the SD card is in low disk space, you need to free up space or use a larger SD card. 
  • Long-term data protection. The cloning method makes an exact copy of the SD card, so you can recover them quickly when it is failing, or infected by a virus. 
  • As a fast recovery method. Once your SD card is damaged or corrupted, you can directly replace it with a new one, with no restore and data loss. 

Besides, data transferring between SD cards is also a factor that leads to SD card cloning. Nevertheless, what counts next is to figure out how to clone SD card to SD card in Windows 11/10/8/7 securely and efficiently.

Before You Clone the SD Card

Before you start cloning an SD card, there are a few things you need to do. Take an example of cloning an Android SD card to a larger SD card.

  1. Transfer all data to the Android SD card: The data on the Android device may not be completely stored on the SD card, so you need to transfer it first.
  2. Get your target SD card: Make sure it has enough space to hold everything from the source card.
  3. Backup files on the target SD card: The target SD card will be overwritten after cloning, thus if there are any important files, please backup them in advance.
  4. Two SD card readers: The SD card can only be connected to the PC through the card reader, so please prepare 2 card readers and make sure they are recognized by your PC.
  5. Download and install SD card cloning software: Cloning an SD card can be tricky and time-consuming, but there's software out there that makes it easier.

AOMEI Backupper Standard is free yet professional SD card cloning software that earns its reputation due to its reliable and powerful features. It can help you clone SD cards to bigger as well as smaller SD cards easily.

How do I clone my SD card to a bigger SD card? With the best SD card cloning software AOMEI Backupper, copying an SD card to a bigger one is a breeze thanks to its easy-to-use interface. Please follow the steps below:

4. (Optional) Click on Edition Partitions to resize the larger SD card size. Please upgrade to the Pro or higher versions to enjoy the following features:

  • Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
  • Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. More flexible but requires human intervention.

Note: The Sector by Sector Clone option will clone all sectors of the source SD card whether they are used or not. Checking it will make Edition Partitions unavailable.

5. Confirm your operation and click Start Clone to clone the SD card to a larger card easily. Wait for the process to complete.

★Tips:
 To clone a specific partition only, please choose Partition Clone in the first step.
 You're allowed to clone an SD card to a USB flash drive or SSD through the above steps.
 Except for SD cards, you are able to use this software to clone hard drives or SSDs, regardless of disk size and model, such as cloning Windows 10 to NVMe SSD, cloning hard drive to larger drive, cloning large HDD to smaller SSD,  etc.
 If you cannot connect two SD cards to your computer simultaneously, it is suggested to do the backup & restore operation for the SD card copy to another one.
