3 Solutions for Recovering Lost Data from CFexpress Card: A Comprehensive Guide

PAGE CONTENT:

CFexpress cards are among the fastest and most reliable storage solutions available today. Designed primarily for high-performance applications such as professional photography, videography, and data-intensive tasks, CFexpress cards offer superior speed and durability compared to traditional SD cards. However, like any storage medium, CFexpress cards are susceptible to data loss due to accidental deletion, formatting, corruption, or even physical damage.

Losing valuable photos, videos, or other critical data can be devastating. Fortunately, there are several ways to recover lost data from a CFexpress card. In this detailed guide, we will explore the causes of data loss, immediate steps to take, recovery methods using software, manual techniques, and professional services. Additionally, we will discuss best practices to prevent future data loss.

Overview of CFexpress Cards

Introduced by the CompactFlash Association (CFA), CFexpress cards are widely used in high-end DSLR and mirrorless cameras, as well as professional video cameras and industrial applications. Their speed and efficiency make them ideal for capturing 8K video, high-resolution RAW images, and burst-mode photography without buffering issues.

Types of CFexpress Cards:

CFexpress cards are available in multiple form factors, each catering to different devices and performance needs. The three primary types are:

1. CFexpress Type A
   • Smaller in size (20mm × 28mm × 2.8mm).
   • Uses a single PCIe lane, offering speeds up to 1000 MB/s.
   • Commonly used in high-end mirrorless cameras (e.g., Sony Alpha series).
2. CFexpress Type B
   • Similar in size to XQD cards (38.5mm × 29.6mm × 3.8mm).
   • Utilizes two PCIe lanes, reaching speeds up to 2000 MB/s.
   • Popular among professional photographers and videographers (used in cameras like the Canon EOS R5 and Nikon Z9).
3. CFexpress Type C
   • The largest (54mm × 74mm × 4.8mm).
   • Equipped with four PCIe lanes, delivering speeds beyond 4000 MB/s.
   • Primarily used for industrial and high-end video applications.

Key Advantages of CFexpress Cards:

1. Blazing Fast Speeds: With PCIe 3.0/4.0 support, CFexpress cards are much faster than SD cards, enabling seamless 8K video recording and burst photography.
2. High Storage Capacities: Available in sizes ranging from 64GB to over 2TB, offering ample space for professional-grade media files.
3. Improved Durability: CFexpress cards are built to withstand extreme temperatures, shock, and vibration, making them reliable for fieldwork and rugged environments.
4. Backward Compatibility with XQD: Some cameras that previously used XQD cards can support CFexpress cards via firmware updates.

Immediate Steps to Take After Data Loss on CFexpress Card

If you have lost data from a CFexpress card, act quickly to improve recovery chances:

1. Stop Using the CFexpress Card Immediately

Continuing to use the CFexpress card after data loss increases the risk of overwriting lost files, making recovery impossible.

2. Avoid Formatting or Running Disk Checks

Do not format the CFexpress card or attempt to repair it using built-in disk tools (e.g., Windows Check Disk or macOS First Aid). These actions may further damage the file structure.

3. Store the Card Safely

If the card has physical damage, avoid inserting it into a reader, as this could worsen the situation. Instead, place it in an anti-static bag and consult a professional recovery service.

3 Main Methods to Recover Lost Data from a CFexpress Card

Whether you are a Mac user or a Windows user, you can use the three main methods to recover lost data from your CFexpress card. If the CFexpress card gets corrupted, you can use CHKDSK, Disk Management (for Windows) or First Aid (for macOS) to repair the CFexpress card.

Method 1. Recover Lost Data from CFexpress Card With Data Recovery Software

When data is lost due to accidental deletion, formatting, or corruption, data recovery software can help retrieve files by scanning the CFexpress card for recoverable data. These tools work by analyzing the storage structure and reconstructing lost files.

Data recovery software works by identifying file signatures and metadata that remain on the CFexpress card even after deletion or formatting. It scans for fragments of lost data and attempts to reconstruct them into complete, usable files.

There are two main types of scans:

• Quick Scan: A fast, surface-level scan that finds recently deleted files.
• Deep Scan: A more thorough scan that searches for traces of lost files across the entire storage medium. This process takes longer but increases the chances of successful recovery.

Many recovery tools allow you to preview images, videos, or documents before recovery. Select the files you want to restore and click "Recover."

Step 6. Save Recovered Files to a Different Drive

👉 Important: Do not save the recovered files back to the CFexpress card to avoid overwriting data. Store them on an external drive or computer storage.

Step 7. Check File Integrity

Open the recovered files to verify they are intact and accessible. If some files are corrupted, try using a file repair tool.

💡 Note: Donemax Data Recovery also can help you fix corrupted CFexpress card. Just choose Disk Manager, then select the CFexpress card, click on Repair button.

Method 2. Recover CFexpress Card via Built-in Recovery Features

Before using third-party software, try manual recovery techniques built into your operating system.

1. Windows Recovery Methods

▪️ Checking the Recycle Bin

• If files were recently deleted, they might still be in the Recycle Bin.
• Open the Recycle Bin > Search for the deleted file > Right-click and select Restore.

▪️ Using Windows File History

If File History was enabled before data loss, previous versions of files might be recoverable:

• Right-click the folder where the files were stored.
• Select Restore previous versions and choose an available backup.

▪️ Running Command Prompt Recovery

Sometimes, missing files can be restored using the CHKDSK command:

Open Command Prompt (Admin). Type: chkdsk X: /f (Replace "X" with your CFexpress card's drive letter).

This will attempt to fix file system errors and restore lost files.

2. Mac Recovery Methods

▪️ Checking the Trash Bin

• Open the Trash and look for deleted files.
• If found, right-click and choose Put Back.

▪️ Using Time Machine Backup

If you regularly back up your Mac, Time Machine can restore lost files:

• Connect your backup drive.
• Open Time Machine and browse past snapshots.
• Select the files and click Restore.

▪️ Running Disk Utility First Aid

If the CFexpress card is unreadable, use Disk Utility to repair it:

• Open Applications > Utilities > Disk Utility.
• Select the CFexpress card and click First Aid to fix file system errors.

Method 3. Professional Data Recovery Services

If software-based recovery fails or the CFexpress card has physical damage, professional data recovery services may be necessary.
