Resolving SD Card Capacity Issues: Tips and Solutions for Optimal Functionality
Confronting storage issues with your SD card can be frustrating, especially when your device only recognizes a fraction of the card's actual capacity. In this article, I'll guide you through the steps to resolve common issues related to incorrect SD card capacity and format it properly, ensuring your media and files are stored efficiently.

For larger cards, it might show 27 GB instead of 64 GB or 59 GB. In this article, we'll explore why this happens and how to resolve the issue.
Common Causes of Incorrect SD Card Capacity
Several reasons can contribute to incorrect SD card capacities, such as:
