⚠ EMERGENCY — Quick response
If you have just lost data: 1) Turn off the device NOW. 2) Do not install anything on the affected drive. 3) Do not open the hard drive. 4) Write down what happened. 5) Call a professional lab: 900 899 002 (free). Every minute of use reduces the chances of recovery.
Disconnect the power supply, USB cable, or turn off the phone. On SSDs with active TRIM, data can be erased within minutes.
Each boot triggers automatic writes (journaling, swap, logs) that overwrite deleted data.
Installing programs writes new data over the lost files. If you want to try software, do it from ANOTHER computer.
HDDs have nanometre tolerances. Opening them outside a clean room introduces particles that scratch the platters.
Clicking? Not detected? Accidental deletion? Dropped? Error message? This information speeds up the diagnosis.
Logical: deletion, formatting, corruption. Physical: noises, clicks, won't boot, impacts. If physical, go straight to the lab.
Look for: ISO Class 5 clean room, ISO 9001/27001 certifications, PC-3000, «no data, no fee» policy. Free phone: 900 899 002
