A data structure for advancing data encoding through a memory block is provided to offer more security when a plug-and-play storage device stores the data by encoding the data through the data block. A double FAT(File Allocation Table)(50,60) advances encoding of each FAT entry and a cluster matched with each fat entry, and hides an encoded index file to a reserved entry with a specific encoding mode. A root directory(70) deletes a file entry of original data. A data area(80) stores the file entry, the FAT entry, and the matched cluster by a storage path of the index file. An MBR(Master Boot Record)(10) stores encoding record of the encoding mode.
