Introduction
When valuable data disappears, it’s more than just files—it’s memories, projects, and sometimes a business’s lifeline. This was the case when a client brought a corrupted 64GB Lexar Professional SD card to our data recovery lab, Hex Technology. Through a combination of experience, precision, and cutting-edge recovery techniques, we turned potential loss into full restoration.
What Went Wrong with the Lexar SD Card?
The 64GB Lexar SD card—a favorite among photographers for its speed and reliability—had become completely unreadable. The user couldn’t access a single file. Upon initial evaluation by our team at Hex Technology, several potential causes were identified:
- Sudden power interruption during data transfer
- File system corruption due to improper ejection
- Logical or physical damage resulting from wear and tear
The card appeared “dead,” with no detection even on professional-grade recovery equipment.
Hex Technology’s Advanced Recovery Process
🔍 1. Diagnostic and Inspection
Our engineers at Hex Technology's data recovery lab performed a complete diagnostic using forensic imaging and card-level tools. Standard recovery methods failed, which indicated the need for advanced intervention.
🧩 2. Chip-Off Data Recovery
Since the SD controller was unresponsive, we implemented chip-off recovery, a high-level recovery method involving:
- Carefully removing the NAND flash memory chip from the card
- Using advanced tools to read raw binary data directly from the chip
- Completely bypassing the damaged controller for clean access
🔄 3. Data Extraction and Reconstruction
After data was successfully extracted, our team:
- Recovered fragmented data blocks
- Rebuilt file structures using file signature pattern recognition
- Restored all files—including JPG, MOV, and DOC—ensuring full data integrity
✅ The Result: 100% Data Recovery Success
Our Hex Technology team successfully recovered 100% of the critical data, including high-resolution photos and video content. The client was overjoyed to have their irreplaceable digital memories restored.
This case demonstrates how professional expertise and specialized techniques can bring "dead" storage back to life.
🛡 Pro Tips to Prevent SD Card Data Loss
- Always eject SD cards safely before removing from devices
- Make it a habit to back up files regularly to a secondary storage location or cloud
- Don’t reuse old cards for critical tasks—NAND flash wears out over time
- At the first sign of issues (e.g., slow speeds, read errors), stop using the card immediately and contact a data recovery lab
Conclusion
The successful recovery of data from the 64GB Lexar SD card isn’t just a technical win for our team at Hex Technology—it's proof that no data loss is final when you rely on experienced professionals. With precision tools, a clean-room environment, and in-depth technical expertise, even severely damaged storage devices can be restored.

It depends on the level of damage. In many cases, especially with chip-off methods, data recovery is very successful.
It’s a method where the memory chip is physically removed from the card and read with specialized tools, bypassing the damaged components.
Most recoveries are completed within 1 to 2 business days, depending on complexity.
These tools can be risky. For physically damaged or unresponsive cards, they may worsen the situation. Professional labs like Hex Technology are always the safer option.
