USB Flash Drives and Memory Cards
МWe extract data from USB flash drives and memory cards of all types for household, industrial, and special purposes. We solve the most exotic problems. In case of suspicious operation of a USB flash drive or memory card, it is necessary to immediately backup the necessary files.
Attention! If the memory chip or memory chip installed in the memory card is physically damaged, the data will be permanently lost. A characteristic damage is a fracture, or cracks in the area where the microcircuits are located.
Typical Signs of Faulty USB flash Drives and Memory Cards
1. USB flash drive or memory card is not recognized by the computer.
2. The necessary files do not open, it freezes during copying, or writing, to a memory card or USB flash drive.
3. USB flash drive or memory card is defined with zero volume.
ОThe Main Causes of Malfunctions of Flash Drives and Memory Cards
(USB Flash, CF, SD, XD, SMC, M2, XQD, PCMCIA, SxS, UFC, TF, iStick, SFM, µcard, NT, NT+, etc.)
USB flash drives, like some memory cards, can consist of separately located functional units (controller, memory chips, power circuit, indication circuit), hybrid type, or united in a single-piece case in a monolithic design.
These devices are not highly reliable. As a rule, not expensive electronic components are used for their manufacture. Due to the scarcity of quality semiconductors on the market, many firms may use rejected NAND memory chips in the manufacturing process. Installed controllers use translation methods, and error correction algorithms, write / read parameters, which are not as advanced as those of SSD drives. Such devices are intended for temporary storage of duplicates, copies of the main files, or for copying copies of files to another device, or for transferring/copying to a computer. There are solid-state data carriers of increased reliability in industrial and military versions.
Problems in the operation of any USB flash drives and memory cards may arise in such cases:
1. Software failure of the translator after unsafe removal from the computer.
2. Software failure of the translator when a flash drive or memory card is operating outside the allowable temperature range.
3. Failure of the translator as a result of physical damage to the memory crystal.
4. Failure of the translator as a result of natural wear and tear of memory cells.
5. As a result of physical damage to the interface connector, memory chip, controller, or other elements of the device.
6. Physical damage (rupture) of micro conductors, or damage to the topology of the printed circuit board.
For data extraction, in most cases, we use complex solutions based on the use of special equipment. Restoring data from a USB flash drive or card depends on the cause of the failure, the type of device, the physical condition of the memory cells, and the need to use special error correction methods.
Attention! Any attempt by unqualified intervention in such a drive can lead to partial or complete loss of information with the impossibility of recovering it in the future.
