Why Your iPex II Action Camera Keeps Saying “SD Card Full” (And What to Do About It)

You’re out on a hike, capturing breathtaking mountain views, or maybe you’re shredding the slopes on your snowboard. You hit record, and suddenly—your iPex II action camera flashes the dreaded message: “SD Card Full.” Cue the frustration. You’re not alone. Many users face this issue, often at the worst possible moment. But here’s the good news: it’s rarely a death sentence for your adventure footage. In most cases, it’s a solvable problem with a few smart fixes and habits.

Over the past few years, I’ve used the iPex II extensively—from beach vacations to mountain biking trails—and I’ve learned that the “SD card full” error is more of a nudge than a failure. It’s your camera’s way of saying, “Hey, I’m running low on space, and we should talk about how you manage your storage.” Whether you’re a first-time action camera user or a seasoned pro, understanding what causes this message and how to prevent it can save your next big moment. In this guide, I’ll walk you through the most common causes, practical solutions, and long-term tips to keep your iPex II running smoothly—no more missing out on golden shots.

Understanding the “SD Card Full” Message on the iPex II

What Triggers the Alert?

The “SD Card Full” message appears when your iPex II action camera detects that the memory card has no available space to store new video or photo files. This might seem obvious, but the real triggers go beyond just running out of storage. For example:

• You’ve recorded high-resolution 4K footage, which eats up space quickly.
• The SD card is fragmented or has corrupted file systems, making it inefficient.
• You’re using a low-quality or counterfeit card that misreports its capacity.
• The camera’s file system can’t create new files due to formatting issues.

I remember a trip to the Grand Canyon where I thought I had a 64GB card, but after recording just two 4K clips (about 10 minutes each), the camera stopped. Turns out, 4K video uses roughly 200–300MB per minute, so even a large card fills up fast. It wasn’t the card—it was the file size.

Is It Really Full—Or Just Acting Like It?

Sometimes, the iPex II reports “SD Card Full” even when there’s space. This usually happens due to:

• File system corruption: The card’s file table gets corrupted, so the camera can’t see free space.
• Hidden files or folders: Some cards come preloaded with manufacturer files or hidden system data.
• Write protection: If the SD card’s physical switch is locked (on microSD adapters), the camera can’t write new files.

One time, I borrowed a friend’s 32GB card and kept getting the error. I checked the card on my computer—only 8GB used! After formatting it, the camera worked perfectly. The issue wasn’t space; it was a corrupted file system.

Immediate Fixes When Your iPex II Says “SD Card Full”

Step 1: Check the SD Card Capacity and Usage

Before panicking, verify the actual storage status:

• Turn off the iPex II and remove the SD card.
• Insert it into your computer using a card reader or adapter.
• Check the total capacity and used space (right-click the drive > Properties on Windows, or Get Info on Mac).

For example, a 64GB card should show around 59–60GB usable space after formatting. If it shows less, it might be a counterfeit card. I once bought a “128GB” card online that was actually a 16GB card with fake labeling. It filled up instantly and caused constant errors. Always buy from reputable sellers.

Step 2: Format the SD Card (Safely)

Formatting clears all data and resets the file system. It’s the most effective fix for false “full” messages.

• Back up any important files first.
• Insert the card into your computer.
• Use the built-in formatting tool:
  • Windows: Right-click the SD card > Format > Choose “FAT32” or “exFAT” > Start.
  • Mac: Open Disk Utility > Select the card > Erase > Choose “MS-DOS (FAT)” or “ExFAT” > Erase.
• After formatting, reinsert the card into the iPex II and power it on.

Note: Use exFAT for cards 64GB and larger. FAT32 has a 4GB file limit, which can cause issues with long 4K videos.

Step 3: Use the Camera’s Built-in Format Option

The iPex II has a built-in formatting tool, which is convenient and tailored to the device.

• Go to Settings > Storage > Format SD Card.
• Confirm the action. This erases all data.
• Wait for the process to complete (usually 10–30 seconds).

Pro tip: I always format the card inside the camera after buying a new one. It ensures compatibility and avoids file system mismatches.

Step 4: Check for Write Protection

Some microSD cards come with an adapter that has a physical lock switch. If it’s in the “locked” position, the camera can’t write to the card.

• Check the side of the SD adapter for a small switch.
• Slide it to the “unlocked” position (usually downward).
• Reinsert the card and try recording again.

I learned this the hard way during a kayaking trip. My camera wouldn’t record, and I thought the card was broken. Turns out, the switch was flipped—classic user error!

Choosing the Right SD Card for Your iPex II

Capacity: How Much Do You Really Need?

The iPex II supports SD cards up to 256GB, but bigger isn’t always better. Here’s a quick guide based on usage:

Card Size	1080p (30fps)	4K (30fps)	Best For
32GB	~4 hours	~1 hour	Casual use, short trips
64GB	~8 hours	~2 hours	Weekend adventures
128GB	~16 hours	~4 hours	Extended trips, vlogging
256GB	~32 hours	~8 hours	Professional use, long expeditions

For most users, a 64GB or 128GB card strikes the right balance between cost and capacity. I use a 128GB card for multi-day trips and swap it out every 3–4 days.

Speed Class: Don’t Skimp on Write Speed

The iPex II requires a minimum Class 10 or UHS-I U1 card for 4K recording. Slower cards can’t keep up, causing dropped frames or recording errors.

• Class 10 / U1: Minimum for 1080p and basic 4K. Good for casual use.
• U3 / V30: Recommended for 4K and high-bitrate modes. Prevents “SD Card Full” due to write errors.

I once used a cheap Class 4 card for 4K recording. The camera kept stopping with “SD Card Full” even though there was space. The card couldn’t write fast enough, so files were incomplete or corrupted. Lesson learned: invest in a U3 card.

Brand and Reliability: Stick to Trusted Names

Not all SD cards are created equal. Avoid no-name brands from random online sellers. I recommend:

• SanDisk Extreme – Reliable, fast, and widely tested.
• Lexar Professional – Great for 4K, durable.
• Kingston Canvas Go! – Budget-friendly but solid performance.

One of my SanDisk cards has survived drops, rain, and extreme temperatures—still works like new after two years.

Long-Term Storage Management Tips

Create a Backup Routine

Even if you have a huge card, always back up your footage. I follow a simple system:

• At the end of each day, transfer files to my laptop.
• Use a dual-drive backup (external SSD + cloud storage).
• Label folders by date and location (e.g., “2024-07-15_MtRainier_4K”).
• Delete files from the SD card only after confirming backups are complete.

This habit saved me during a hiking trip. My camera fell into a stream, but all my footage was safely backed up.

Use Multiple Cards (and Rotate Them)

Instead of one giant card, use 2–3 smaller ones. Benefits:

• Lower risk of losing all footage at once.
• Easier to organize by day or activity.
• Quick swap if one card fails.

I carry two 64GB cards. After one fills up, I pop in the other and keep going. No downtime.

Enable Loop Recording (For Specific Use Cases)

The iPex II has a loop recording mode that overwrites old files when the card is full. It’s great for:

• Dashcam-style use (e.g., biking, commuting).
• Situations where you only need the most recent footage.

To enable it: Settings > Video Mode > Loop Recording > 5min/10min/30min. The camera will record in chunks and overwrite the oldest ones when space runs out.

Warning: Don’t use this for events you want to save entirely—like a wedding or race. You’ll lose the beginning.

Preventing Future “SD Card Full” Issues

Format Regularly (Even When Not Full)

Think of formatting like cleaning your camera’s digital memory. I do it:

• After every major trip.
• Before using a card for the first time.
• If the camera behaves oddly (slows down, freezes).

Regular formatting prevents file system bloat and keeps the card running smoothly.

Check for Firmware Updates

Outdated firmware can cause storage bugs. The iPex II team occasionally releases updates that improve SD card compatibility.

• Visit the official iPex website.
• Download the latest firmware.
• Follow the instructions to update via SD card.

I updated my firmware last year and noticed fewer “full” errors with older cards.

Handle Cards with Care

Physical damage can cause false storage errors. Tips:

• Always power off the camera before removing the card.
• Use a protective case for storage.
• Avoid extreme heat or moisture (e.g., leaving it in a hot car).

One of my cards failed after being left in a beach bag for a week—sand and saltwater did it in. Now I store mine in a waterproof case.

Final Thoughts: Keep Rolling, No Matter What

The “SD Card Full” message on your iPex II isn’t a failure—it’s a reminder to stay organized and prepared. With the right card, smart habits, and a few quick fixes, you can keep capturing those unforgettable moments without interruption. I’ve learned to treat my SD cards like my camera: essential gear that deserves care and attention.

Remember, the best fix is prevention. Invest in a quality U3 card, format regularly, and always have a backup plan. Whether you’re chasing waterfalls or racing down trails, your iPex II should be the last thing holding you back. So go ahead—hit record, and don’t let storage worries steal your spotlight.

And if you ever see that “SD Card Full” message again? Take a breath, follow these steps, and get back to what you love. Adventure awaits—and your camera’s ready to capture it all.
