Problems solved by technology

The function of this device to complete the basic virtual partition is relatively expensive, and it is only effective for the IDE interface, and has no feasibility and practical value for other interfaces. In fact, except for the description of the IDE interface, it is not seen in its manual for other interfaces. Description of the interface

Abstract

A external storage conversion device is used to converse an interface of external storage to other different; meantime, it divides external storage to multiple virtual sub-storages with write-protect function and safe shared, and can encipher external storage or sub-storage. The virtual dividing supports the replacing for external storage; and set sub-storage of system layout to provide virtual dividing configuration with convenience and safety.

Description

technical field [0001] The present invention relates to the interface conversion technology of the external memory, especially relates to the virtual separation technology of the external memory. Specifically, the device divides the external memory into multiple virtual sub-memory, and can encrypt the external memory or the separated virtual sub-memory. Background technique [0002] The interface conversion of the external memory is mainly used to convert one type of external memory interface to another interface so as to be accepted by the host system, and the purpose is generally to improve compatibility and mobile interchangeability. Such as: Common Universal Serial Bus (USB) to IDE (including EIDE interface, the same below) interface, 1394 to IDE interface, SATA to IDE interface, etc. Generally speaking, the one connected to the host system is called the first interface, and the one connected to the external memory is called the second interface, and the first interface...
