WD My Passport NVMe data recovery — case study of a difficult case

Case description

Symptoms reported by the client — the laboratory received an external drive WD My Passport NVMe, containing approx.1.3–1.8 TB of data, collected over many years.
The device wasvirtually dead on arrival— no stable response, identification problems and system freezes during read attempts.

Condition of the device on arrival

The drive did not behave consistently — sometimes it was detected, at other times it disappeared from the system completely. Every read attempt ended with the computer slowing down or freezing, which in practice ruled out any safe home recovery and clearly indicated the need forSSD data recovery in the laboratory.

Additional complication: the USB enclosure

An additional problem was thetight, integrated USB enclosure, designed in a way that significantly hindered safe disassembly. Opening such a case without the right tools can lead tomechanical damage to the electronics or the drive itself.

Symptoms reported by the client — details

How the drive behaved in the system

• complete lack of access to data,
• the drive disappeared from the operating system at random,
• read attempts caused the computer to freeze,
• very slow response from the device or no response at all.

Initial technical diagnosis

After safely disassembling the enclosure and starting the device on a laboratory workstation, a detailed diagnosis was performed.

Key findings after diagnosis

• unstable operation of the NVMe controller,
• advanced NAND memory degradation,
• strong tendency to overheat during reads,
• damage to the logical data structure(the partition was in RAW state).

Risk assessment

This was ahigh-riskcase in which standard methods (copying data in the operating system) could have led toirreversible data loss.

Main risks in this case

In NVMe devices, even reading data alone creates intensive load on the controller and the internal memory-management structures.

What could have caused the device to lose identification

• system freezes and hard resets,
• sudden power interruptions,
• controller overheating during long read sessions.

Any of the factors above could have led to a situation in which the devicewould stop identifying itself, making any further data recovery impossible.

Laboratory procedure used

To minimise the risk, we applied acontrolled laboratory procedure, adapted to an unstable NVMe device. At the "what to do next" stage, these cases often end withprofessional SSD data recovery, because the firmware may block further readout.

Protective measures used

• a hardware USB stabiliser for work with unstable devices,
• controlled, stable power supply with UPS protection,
• active cooling of the device (maintaining a constant working temperature),
• staged sector-by-sector imaging with a limited number of retries,
• workonly on a copy (image), not on the original device.

Imaging process

The imaging process lastedmany hoursand was interrupted with controlled pauses to avoid further degradation of the device and loss of communication.

Result of the work

We managed to createan image of the device, which made further analysis and data recovery possiblewithout risking deterioration of the drive's physical condition.

Key conclusions

• maintaining stable working conditions was crucial,
• without cooling and stabilisation, the device could have lost identification,
• in cases like this,time and safety matter more than speed.

Why this kind of recovery is not "cheap"

This case shows that recovering data from modern NVMe devices is not just "a program and a cable", but:

What makes up the cost of the service

• specialist laboratory equipment,
• years of experience working with unstable devices,
• real risk of irreversible data loss if wrong decisions are made,
• a long, controlled imaging process.

That is why the service price reflects thelevel of risk and responsibility, not just the amount of data.

Summary

NVMe drives, especially in external USB enclosures, can fail suddenly and unpredictably.
In such cases,uncontrolled recovery attemptscan permanently close the way back to the data. If you want to understand what affects the quote, see the guide:how much data recovery costs.

When to stop trying and hand the device over to a laboratory

If the device:

• freezes the system,
• overheats,
• disconnects at random,

the best decision is to stop testing, keep the enclosure in its current state, and hand the device over for controlled laboratory diagnosis before it loses identification completely.

Why integrated USB NVMe cases require extra caution

Many users treat this type of device like a classic external HDD and assume they can simply move the memory module to another enclosure. In practice, integrated WD My Passport designs can make safe access harder because the housing, bridge board, cooling conditions, and controller behavior all influence stability. If the device already freezes the system, every improvised attempt increases the risk that the controller will stop identifying altogether.

That is also why these cases should be compared with guides such as SSD not detected in BIOS and SSD/NVMe bricking. The symptom may look similar from the user side, but the safe laboratory path is different from a normal home copy attempt.

What the client should prepare before handing such a device over

Before the handoff, the most useful things are not more tests but better notes: whether the disk ever showed the correct capacity, whether the problem started after overheating or a sudden disconnect, and whether the enclosure was opened before. That short history can save time during diagnosis and reduce the number of risky power-on attempts. When a client wants to understand the broader process, it also helps to read how TRIM and garbage collection affect SSD recovery and what shapes the cost of data recovery.
