Case Study Summary
- Client: Adrian (business owner, Australia)
- Device: 2.5-inch SATA SSD
- Problem: SSD not recognised due to NAND degradation
- Solution: Firmware-level translator rebuild
- Outcome: Majority of critical business data recovered
This SATA SSD NAND degradation case study documents how Payam Data Recovery engineers recovered critical business files from a failed SSD that was no longer recognised by any computer. With a project deadline approaching, the device had become completely inaccessible and required firmware-level recovery work.
The problem: SSD not recognised by computer
The 2.5-inch SATA SSD arrived as a Priority service. The client reported that the drive was not detected at all, which can indicate an advanced SSD firmware issue rather than a file system problem.
Diagnostic testing confirmed NAND flash degradation. When NAND memory deteriorates, the SSD controller can enter a busy state after power-up, preventing the drive from presenting data to the operating system. Further technical background on NAND flash memory is available on
Wikipedia.
SATA SSD NAND degradation case study process
The recovery process focused on rebuilding the SSD translator, a firmware component that maps logical file locations to physical NAND memory cells. Without a functioning translator, data stored on the NAND chips cannot be accessed even if the memory itself remains readable.
Using specialised SSD firmware tools, the engineer reconstructed the translator to restore communication between the controller and the NAND memory. Once rebuilt, data extraction could begin in a controlled manner.
Recovery results
The engineer explained that recoveries involving NAND degradation may not always preserve a perfect file structure. In this case, most recovered data was presented in a raw format. Despite this limitation, the majority of the client’s critical business files were successfully retrieved.
This SATA SSD NAND degradation case study also shows why acting quickly matters. Reducing further NAND deterioration can improve the overall recovery outcome.
Why professional recovery matters
Unlike mechanical hard drives, SSD failures are firmware and electronics based. Standard software tools and general IT repair services cannot address NAND degradation or a corrupted translator. Professional SSD recovery requires specialised equipment, firmware access, and experience with different controller architectures.
Attempting DIY recovery on an unrecognised SSD can permanently reduce recovery chances.

Frequently asked questions
What is SSD NAND degradation?
NAND degradation occurs when flash memory cells wear out or become unstable, preventing the SSD from correctly accessing stored data.
Can data be recovered if an SSD is not detected?
In many cases, professional recovery is possible using firmware-level techniques.
Why does an SSD enter a busy state?
Severe NAND degradation can prevent the controller from completing internal processes, leaving the drive inaccessible.
How long does SSD NAND degradation recovery take?
Turnaround time depends on service level and complexity. Economy services are slower, while Priority and Emergency options provide faster processing.
