Magnetic Force MicroscopySpecialist clean room lab equipment exists to handle particularly difficult recovery assignments. When conventional data recovery methods have failed, magnetic force microscopy can be used to analyse the magnetic patterns stored on a medium. This is then converted into readable data and recovered to new media. This technique of data recovery has proved successful on numerous occasions where other methods have failed; such as Track 0 damage, fire damage, flood damage, impact damage and overwritten data. This machine is a result of proprietary software, electronics and positioning systems. The machine is used both for advanced data recovery and quality assurance of data erasure. There are several steps in the actual recovery process: The first step is to customise our equipment to the individual hard disk. Based on information from the manufacturer and comprehensive analysis, we perform a diagnosis of the disk. The next step is to physically retrieve data from the damaged disk. We disassemble it in one of our clean rooms, clean and mark the platters. The platters are then fitted onto the special machine, which scans every single surface and picks up analogue signals from the disk. Finally these signals are digitised and converted into readable data stored on a new medium. The quality of the copy depends on how severely damaged the original disk was. The last step is to analyse the copy in order to determine the logical structure of partitions, file systems and files. When the analysis is finished, the file system is rebuilt and data is accessible to the user again. The equipment is independent of hard disk type and model. Further research
