Abstract
A method is disclosed for recovering data associated with a damaged file stored in a NAND gate array memory. The method includes the steps of: identifying all meta data associated with the damaged file; identifying each logical block address of all identified meta data; collecting all physical block addresses associated with one of the identified logical block addresses or the identified meta data; counting in a replace table (ReplTable) a number of matches to a physical block address of the damaged file for each physical block address of the damaged file; choosing a block in a linked list that corresponds to the physical block address of the block in the linked list; and linking all chosen blocks to form a replicated file.
