Before the complete failure occurred, the SSD began displaying several progressive symptoms, including:

• Intermittent system freezes
• CRC and I/O errors
• Sudden file corruption
• Slow response before eventually becoming undetectable in BIOS

As these issues increased in frequency, they eventually led to the drive becoming fully undetectable.

However, Standard software diagnostics posed a high risk of metadata damage and translator overwrite. As a result, the SSD eventually entered an unresponsive state, clearly indicating a controller-level failure that required our engineers to perform NAND extraction and FTL reconstruction.

Many ADATA SU650 SSD Data Recovery cases show similar issues:

• Unstable SLC cache behavior
• Firmware-induced controller lockups
• Logical-to-physical mapping corruption
• FTL table damage during controller degradation

However, although the NAND memory chip was intact, we needed direct chip access to retrieve the data. As a result, the challenge involved rebuilding the entire logical structure from raw dumps without relying on the failed controller.

The recovery process required:

• Raw NAND dump extraction
• FTL rebuilding and logical block mapping
• Partition table and metadata repair
• Directory hierarchy reconstruction
• Application-level file validation

Our SSD recovery specialists executed a controlled, safe, and systematic recovery:

1. First Diagnosis

First, our specialists confirmed the controller failure and identified a non-responsive translator along with corrupt firmware structures.

2. NAND Chip-Off Extraction

Next,  our engineers carefully removed the NAND chip in an ESD-safe environment, and safe reads were performed using adaptive parameters to avoid stressing weak cells.

3. Raw Data Dumping & ECC Processing

In addition, we extracted all NAND pages using error-managed reads, followed by ECC correction and rebuilding of page-level structures.

4. FTL Reconstruction

Subsequently, our team rebuilt the logical mapping tables, and damaged translator structures essential for block addressing were restored.

5. File System Repair

Then, our specialists repaired the file system, including partition boundary reconstruction, MFT repair, and restoration of the original directory hierarchy.

6. Integrity Verification

Finally, we opened and verified all critical files—including documents, images, project files, and media—were opened and checked through checksum-based validation to confirm full usability.

As a result, DataCare Labs successfully recovered 100% of the accessible 352GB data, including all high-priority files.

Key achievements:

• In summary, the original folder structure was fully restored.
• No additional wear was introduced to the NAND.
• All files have been tested and verified for functional usability.
• Delivered clean, ready-to-use data to the client.
• Provided customized backup and SSD health maintenance guidelines.

If your ADATA SU650 SSD becomes undetectable, freezes, or shows controller errors, stop using it immediately.
