How to Properly Format MicroSD Cards for Drones and Action Cameras

Formatting your microSD card correctly is one of the most important steps to ensure reliable recording and optimal performance. Many recording issues, corrupted files, and performance problems can be traced back to improperly formatted cards.

Why Formatting Matters

Formatting ensures the file system remains optimal for storing and retrieving data, helping organize the data structure and making the card more efficient for writing and reading information. When you format a card in your device, it creates the exact folder structure the camera or drone needs and eliminates stray files that could cause problems.

Understanding File System Formats

There are two primary file system formats you'll encounter:

FAT32:

  • Use for cards 32GB and under
  • Maximum file size is 4GB (videos will be split into multiple files)
  • Compatible with virtually all devices, including older models
  • More universal compatibility across different brands

exFAT:

  • Required for cards 64GB and larger
  • No practical file size limit (single video file per recording)
  • The most modern and recommended format for high-capacity cards
  • Supports high writing and reading speeds

For your SanDisk Extreme Pro 128GB card, exFAT is the correct format to use.
