ABSTRACT:
A field-operable stand-alone apparatus for recovering data from corrupted flash media and regenerated damaged flash media. The apparatus enables users in the field to recover data from and/or regenerate damaged flash media without requiring the use of a computer. In one aspect, recovery comprises using a low-level access scheme that enables data to be recovered when high-level interfaces, such as file systems, are damaged. The type of flash media is determined, and a corresponding access scheme is employed. Depending on the type of damage to the media, a physical-to-logical table may be built and employed to sequentially access the flash media in search of indicia from which selectable file-types can be identified, or the media may be accessed using normal operating system commands. Once the file indicia are found, the location of corresponding file data is identified, whereupon the file data are read and stored. The apparatus may include a plurality of different connectors to interface with different media form factors, or a universal connector that employs various form-factor adaptors to interface with the different flash media configurations.
