USB Flash Drive and Thumb Drive Recovery

The recovery methods that worked for the past 20 years on electromagnetic disc based hard drives do not apply to USB Flash Drive Recovery and or Thumb Drive Recovery cases. Such NAND flash based technological storage devices as are used in SD cards, thumb drives, USB Flash drives, cell phones, and Solid State disk drives (SSD) are much smaller than magnetic based storage and behaves logically different in the way it stores and retrieves data. These changes are great for the end user but present many problems when it comes to recovering the data. Most consumers are not aware of the difficulty and complexity that is involved at the present time in the extraction process during a Thumb Drive Recovery and retrieval case

Most problems with malfunctioning USB flash devices are the drives onboard controller fails on the PCB (Printed Circuit Board). The flash controller communicates with the computer and manages the data stored in the flash memory. It is the brains of the USB device and without it the computer does not know how to recognize the device or read or write data to the flash memory. If the controller has failed there is usually little that can be done to perform USB Flash Drive Recovery procedures successfully without manually de-soldering the NAND chip(s), reading out the data and reassembling the data structures. This often is a cumbersome process since the data storage algorithms can be very sophisticated and include various variables which have to be dealt with. In addition some devices such as most San Disk controllers have a built in encryption that can further complexify the recovery case.
