Damaged flash stroagesThe amount of flash memory that we process in the laboratory is increasing rapidly, as this type of memory is being used more and more frequently in a variety of storage media.
Common flash drives
- Solid State Drives (SSD)
- Universal Serial Bus-Sticks (USB)
- Secure Digital-Cards (SD)
- Compact Flash-Cards (CF)

Construction and data rescueIn contrast to traditional hard disks, flash media does not use glass or aluminium disks as a storage medium, but instead solely relies on the use of electronic memory chips. However, this does not mean that flash memory is automatically protected against data loss.
Irrespective of the number of installed memory chips, the construction is also decisive on how complex a data rescue will be. To an increasing degree, the memory chips are positioned on top of each other in a “sandwich or monolith construction method” in order to save space. However, this results in a considerably more difficult data rescue, as these can only be unsoldered in groups and must be loosened from each other with very elaborate chemical procedures in order to subsequently be able to read them out.
Error source: Firmware/softwareDue to the fact that flash memory is not constructed with mechanical components, these are highly susceptible to so-called “bugs” in the software and firmware (errors in programming).
Hardware damage however can still occur, for instance due to contact issues between the individual components. A classic example for this is the USB flash drive, which has been connected to the computer and is accidentally brushed while passing the computer and breaks off. In the same manner, the electronic components (PCB) can become faulty. This damage can span from individual memory chips up to the controller, which is in charge of the communication and the wear levelling.
Environmental influencesCompact flash memory cards that are often used in digital cameras can become damaged due to environmental influences, for instance when they are dropped into water or when they become overheated. Our technicians encounter these types of cases again and again and are able to successfully reconstruct the data.
