Formatting an SD card wipes bad or corrupt data and creates a fresh, reliable medium for writing.
You can format it in-camera, or on a Windows PC, Mac and Android device.
Best practice:
- In-camera formatting is the safest and most compatible method.
- Windows or Mac formatting allows you to choose file systems (FAT32, exFAT) for wider device compatibility.
- Do not forget to back up your files and make sure that the device is fully charged before proceeding.
Introduction
Even the best SD cards break down over time: corrupt files, fragmentation, and performance grumpiness are irrevocable byproducts of normal wear and tear.
When you reformat, the file system will be rebuilt and also repair a lot of this.
No matter if you’re shooting weddings, travel blogs, or family photos and videos, maintaining a healthy SD card is important to successful photography and videography on your camera.
The Importance of Formatting Your SD Card
- Clean up useless caches & logs: Delete cache files, trash and other junk to save more disk space.
- Reformat file system: Avoid read/write delay and directory corruption.
- Enhances camera compatibility: Enables your card to meet the firmware’s specification for your usage.
- Extend card lifetime: Optimise delete function to reduce “write” by the device, extending life of card.
(Fact-checked 2025: All major camera brands – Canon, Nikon, Sony, Fujifilm, Panasonic – still advise in-camera formatting after big shoots.)
How to Properly Format an SD Card Using Your Camera (It’s the Best Way)
- Back up your photos/videos to a PC or cloud.
- Charge the camera battery fully.
- Insert the card and power on.
- Reference Menu → Setup/Settings » Format Card (Canon, Nikon: slightly different terminology).
- Acknowledge OK and wait till done then shut off.
Pro Tip: Only ever delete on-camera when absolutely necessary – always opt for a full in-camera format after transferring.

How to Format SD Card on Windows PC
- Insert card via reader.
- Open File Explorer → This PC.
- Right-click the card → Format.
- Choose File System:
- FAT32 (for ≤ 32 GB)
- exFAT (for ≥ 64 GB; supports 4K video & files > 4 GB)
- Tick Quick Format (fast) or untick it for deep clean.
- Click Start → OK.
Pro Tip: If Windows doesn’t recognize the card, open Disk Management → Right Click/Delete Volume → New Simple Volume before formatting.
How to Format an SD Card on Mac (Disk Utility)
- Insert card or reader.
- Open Applications → Utilities → Disk Utility.
- Select the card → Erase.
- Select Format: exFAT (for cross-platform) or FAT32 (“MS-DOS (FAT)”) for older gear.

Pro Tip: macOS 13+ uses exFAT for cards > 32 GB – perfect for recording in XAVC S format and using with Windows.
Formatting vs Reformatting – What Does That Mean?
- Format: New Card Set Up.
- Reformatting: Taking a used card and refreshing it or repairing the errors, or changing file systems.
When to reformat:
- Monthly for frequent shooters.
- When you see slow writing speed or “Card Error.”
- Before reselling or giving away a card (double format is required).
Note: Formatting removes directory pointers, but the data remains on the drive.
Recovery software such as PhotoRec or Recuva may still recover files unless securely erased.
FAT32 vs exFAT (Which Is the Better Format?)
| File System | Best For | Max File Size | Typical Use Case |
|---|---|---|---|
| FAT32 | Cards ≤ 32 GB | 4 GB | Older cameras, dash cams, game console |
| exFAT | Cards ≥ 64 GB | Almost unlimited (> 4 GB) | 4K/8K video, modern DSLRs, Android, computers |
