NAND Recovery | Recover Lost Data from NAND Drive

NAND flash memory is the backbone of modern storage devices, from USB drives and SSDs to smartphones and cameras. However, data loss on NAND-based devices can occur due to accidental deletion, file system corruption, physical damage, or firmware failures. Recovering data from NAND flash requires specialized techniques depending on the root cause of the issue. 

Is It Possible to Recover Data from a NAND Flash Drive?

Yes, data can typically be recovered from a NAND Flash drive, but the success rate depends on the type of loss. Logical failures, such as lost files or corrupted data, have a more significant recovery success rate than physical failures. For logical failures, you can use tools like EaseUS data recovery software. After all, data always comes first.

The chance of recovery depends on the scenario in which the data was lost. Below, we summarize three proven methods to retrieve lost data from NAND flash memory, ensuring you understand when and how to apply each approach.

Fix 1. Software-Based NAND Recovery: Fix Logical Failures

Software-based recovery is the first line of defense for logical issues like accidental deletion, formatting errors, or corrupted file systems. This method leverages advanced algorithms to scan and recover data from the NAND flash's raw memory. When choosing a tool, consider its authority in SSD recovery.

EaseUS Data Recovery Wizard is designed to bypass file system errors, read NAND memory cells, and thoroughly scan the storage device.

Here are the steps:

Step 1. Scan the SSD

Open EaseUS Data Recovery Wizard, select the SSD where you lost data, and click the "Search for Lost Data" button.

Step 2. View the results

When the scanning finishes, find lost SSD data by using the "Filter" and "Search" options after checking the "Deleted Files" and "Other Lost Files" folders.

Step 3. Recover SSD files

Select desired data and click the "Recover" button to get back lost SSD files.

💡Tip: You can restore data on the local disks, external hard drives, and also the cloud storage.

Fix 2. Physical NAND Recovery Services

When the NAND flash memory suffers physical damage - such as a cracked chip, faulty controller, or electrical failure - software alone won't work. Physical recovery involves extracting and reading raw data directly from the NAND chips.

While software tools can resolve logical issues, physical damage and firmware corruption demand professional intervention. You can seek help from reputable data recovery services like:

Fix 3. NAND Firmware Updates: Fix Controller Corruption

NAND flash devices rely on a controller to manage data storage. If the controller's firmware becomes corrupted, the device may become inaccessible despite the intact NAND chips. Here is how to Reflash the Firmware:

Step 1. Use tools like ChipGenius (for USB drives) to identify the controller model.

Step 2. Find the firmware specific to your device's controller. Manufacturers like Samsung or SanDisk provide firmware tools for enterprise SSDs.

Step 3. Connect the device to a hardware programmer (e.g., Flash USB Firmware Updater).

Step 4. Upload the firmware to reset the controller's code and restore access to the NAND memory.

Conclusion

NAND flash data recovery is a nuanced process that hinges on the type of damage. Software tools work wonders for logical issues, but physical and firmware-related failures require professional expertise. By understanding these methods, you can make informed decisions to maximize your chances of data retrieval and minimize the risk of permanent loss.
