How can I restore SD card to full capacity

"I have 16 GB SD memory card. And to recover my Android TV box I've tried to copy a recovery image on to my 16GB SD card using a tool called HDD RAW Copy. But now the card is not showing the correct capacity. The OS only reads 3.68GB while its actual size should be 16GB. And what’s worse, I am not able to reformat my SD card back to its original size. I tried formatting by many steps but no result. I tried using cmd Diskpart and hit enter list disk, select disk “H”, create partition primary. I tried with Disk Manager. Please help me! How do I restore the SD card to full capacity to get my 16GB back?"

Reasons and solution for SD card not showing full capacity

Similar cases can happen on other storage devices like USB flash drive, pen drive, hard drives, memory card, etc. Why is my SD card not showing its full capacity? How can I restore SD memory card to the full size? Users always ask such questions when they encountered the issue.

Usually, SD card not showing full capacity happens because some card readers or host devices are not compatible with the larger SDHC and SDXC cards. If the reader or host is not compatible with the larger capacity, the card will be repartitioned to a size that is supported. For example, if your card reader or camera is compatible with an SDHC card with a maximum capacity of 32GB using this reader or camera to format a 64GB SDXC card will result in the card being repartitioned to 32GB (~27GB usable capacity). And SD card not showing full capacity can also occur due to invisible shadow files, formatting overhead, hidden recovery partitions, and unallocated space. 

If you experience SD card not showing full capacity issue, please don’t worry! Here is a solution. You can use a reader or host that supports the full capacity of the card and use a third-party SD card format tool to restore full capacity on SDHC/SDXC cards with ease.
