FAQ

Yes, in most cases. A hard drive that clicks, scrapes, or makes abnormal noises generally indicates a mechanical failure of the read/write heads. It is essential to turn off the drive immediately to avoid damaging the platters. Our laboratory operates under ISO 5 certified laminar flow to replace the faulty components and extract your data.

Yes, data recovery from physically damaged hard drives is our specialty. SOS Data Recovery has an ISO Class 5 certified laminar flow environment according to ISO 14644-1 (max. 3,520 particles ≥ 0.5 µm per m³) allowing us to open and repair media in dust-free conditions. Defective components are replaced using specialized equipment (PC-3000 from ACE Laboratory) before performing a complete bit-by-bit copy of the media.

An ISO 5 laminar flow (formerly Class 100) is a controlled environment in which the air contains a maximum of 100 particles of 0.5 micrometers per cubic foot. This level of purity is essential for handling the internal components of a hard drive without risking contamination.

A logical failure affects the file system or the data itself (accidental deletion, formatting, corruption, virus). The storage device functions normally, but the files are inaccessible. A physical failure affects the hardware components (read/write heads, motor, memory chips, connector). The storage device does not start, makes abnormal noises, or is no longer detected. A physical failure requires intervention in an ISO 5 cleanroom environment.

The read head of a hard drive floats over the platters at only 7 nanometers. An ordinary dust particle measures 6,000 nanometers, or 860 times that distance. Without laminar flow, any opening of a hard drive would cause an immediate head crash and permanent data destruction.
