Abstract

This invention discloses a data storage equipment and a method for accessing its internal data, among which, the equipment includes: a radio transmit / receive device for transmitting / receiving data, a storage device for storing the transmitted / received data by the radio transmit / receive device, a control device coupled with the two devices separately for controlling them of the data exchange. Multiple outer equipments can share the internal data of the said equipment via radio network. The said equipment can realize radio connection with computers to avoid harm to the computer and the device because of frequently plugging.

Description

technical field [0001] The invention relates to the field of computer peripheral equipment, in particular to a data storage device and an access method for internal data. Background technique [0002] For computer users, data sharing between computers has become an indispensable requirement in daily life. Due to the advantages of simple use and portability, mobile storage devices are favored by users. Common mobile storage products mainly include flash memory and mobile hard disk. The two have mutual advantages, the former is outstanding in portability, while the latter wins in capacity. Mobile hard disk is an important mobile storage device. It has the characteristics of large capacity, easy plug-in and removal, strong security and reliability, and faster read and write speed than other mobile storage devices. [0003] Mobile hard drives are divided into two categories according to different connection methods. One type is the built-in mobile hard disk in the rack, whic...
