Do now
- Switch off the computer or device completely.
- Document the error and preceding event.
- Do not initialise or repartition the SSD.
- Have information about device and drive encryption available.
Data loss guidance
SSD not detected? Stop further startup and write attempts.
SSD controllers, firmware, memory cells, translation tables and often hardware encryption interact. Uncontrolled tools or repeated starts may change the starting conditions.
Further attempts may worsen damage or change recoverable data.
Immediate precautions
Protect the remaining options.
Avoid
- Repeatedly starting or testing the SSD through different adapters.
- Running firmware updates or manufacturer tools.
- Formatting, secure erase or reinstalling the system.
- Writing recovered files onto the affected SSD.
Possible causes
Similar symptoms can have different causes.
A reliable assessment requires examination of the actual medium.
Controller or firmware
The SSD may lose access to internal management and translation tables.
Electronic damage
Power supplies, protection components or other parts may prevent communication.
NAND and management data
Wear or damaged memory areas may affect startup and data mapping.
Encryption and TRIM
Hardware-bound encryption and already executed discard commands may limit the options.
Professional diagnosis
Isolate the fault before reconstructing data.
Storage technology, damage and data priorities determine the route, not a one-size-fits-all software solution.
01 · Check interface and identification
SATA, NVMe or USB connection and technical device status are assessed individually.
02 · Assess electronics and power consumption
Abnormalities are isolated without triggering unnecessary writes.
03 · Evaluate controller access
Model, controller, firmware state and possible encryption determine the route.
04 · Working image and file checks
Readable data is secured under control and the agreed recovery result verified.

Frequently asked questions
SSD not detected? Stop further startup and write attempts.
Why has my SSD suddenly stopped being detected?
Common causes include controller, firmware, electronic or NAND problems. Adapters, mainboard or file system may also be involved.
May I initialise an undetected SSD?
No. If you need the data, do not initialise, format or create a new volume.
Is SSD recovery always possible?
No. Controller state, encryption, TRIM and damaged management data may limit or prevent recovery.
Why should I not keep testing the SSD?
Repeated starts may stress unstable memory states and trigger automatic internal processes.
Does DataDoc assess NVMe SSDs?
Yes. DataDoc assesses SATA, NVMe and external SSDs. Feasibility depends on the model and damage.
