Multimedia file playing method and system for mobile storage device

Abstract

The invention discloses a multimedia file playing method and system for a mobile storage device, and the technical scheme is characterized in that the method comprises the following steps: the storagedevice is partitioned in advance to form a display partition and a hidden partition, specific playing software being stored in the display partition, and multimedia file data being stored in the hidden partition; when the storage device is powered on, only the display partition is reported to be recognized by the host operating system; and a private command is issued to the storage device throughthe specific playing software to determine that the hidden partition exists in the storage device, the multimedia file data is analyzed in the hidden partition and playing action is executed. According to the invention, the purpose of improving the data security in the storage device is achieved.

Description

technical field

[0001] The invention relates to the technical field of playing multimedia files, in particular to a method and system for playing multimedia files used in removable storage devices. Background technique

[0002] NAND Flash (flash memory) is currently the most mainstream non-volatile storage medium. It is widely used in mobile U disks and solid state drives (Solid State Drivers, SSDs) due to its advantages of high performance, low power consumption, shock resistance, and long life. ), mobile memory cards and other common storage products.

[0003] A storage device such as a solid-state hard disk is a hard disk composed of a control unit and a solid-state storage unit (NAND Flash). Solid-state drives use NAND Flash chips to store data. Before data is written, the NAND Flash chip needs to be erased. The basic unit of the erase operation is a block (Block). Each Block contains several pages (Page). Page is the data read The basic unit of write operations. [0...
