Symptoms at intake
- Drive not visible in BIOS/UEFI or disk management.
- Sometimes detected after a cold start and then disappears.
- Computer freezes during access.
- External enclosure shows no stable device.
- The data includes the only current project or company files.
What not to do after detection is lost
- Do not keep power-cycling the drive.
- Do not update firmware during the incident.
- Do not initialise or format if the system prompts you.
- Do not run recovery software against an unstable original.
- Do not write anything to a drive that briefly appears again.
Why this case is difficult
SSD and NVMe media depend on controller state, firmware, NAND translation tables and background cleanup. After power loss, the issue may not be a normal deleted-file case, and TRIM or garbage collection can change what remains available.
Safe lab procedure
Diagnosis starts with controller behaviour, power state and safe read possibilities. If the device can be stabilised, work continues from a controlled image or another controlled recovery procedure, not from repeated user-level scans.
Result and limits
Recovery depends on controller access, NAND condition, encryption, TRIM activity and whether the drive was written to after the incident. The safest practical action is to stop attempts early.

FAQ
Can an SSD be recovered when it is not detected?
Sometimes, but it depends on controller access, firmware state, encryption and NAND condition.
Should I keep trying adapters?
No, not if the drive appears intermittently or freezes the computer. Preserve the current state and ask before another test.
