All flash drives, except monolithic ones, are structured approximately the same: printed circuit board, wiring elements, controller, memory chips, USB connector. If a malfunction occurs, the owner is more interested in saving the recorded data than the flash drive itself. The process of data recovery is significantly different from repair, because there is no need to restore the functionality of the device itself.
Memory chips on which information is recorded fail quite infrequently, since they are protected from this mechanically - by the case, and by the design itself (memory chips, as a rule, are removed from the USB connector), as well as electrically (by the harness and controller, which take on overvoltage, voltage surges, static discharges).
When inspecting memory chips, it is important to pay attention to whether they have mechanical damage - breaks, chips or cracks, surface peeling, burnt or missing contacts. Therefore, first of all, a careful visual inspection of the microcircuits is important, since this is the only way to determine that something is wrong with the microcircuit.
If the microcircuits are damaged, you should choose whether you need more information or the drive itself. In both cases, you can resort to the help of DataRecovery company professionals, who will be able to “pull out” the information and carry out proper repairs to the microcircuit. If the damage is significant, then the microcircuit or the entire drive itself is replaced with new ones.
