Abstract

The invention is suitable for the technical field of storage equipment and provides external storage equipment and a power fail safeguard method thereof. The external storage equipment comprises a main equipment power supply monitoring unit, a control unit and a data processing unit, wherein the main equipment power monitoring unit is used for monitoring the output of a main equipment power supply, and sending a control signal to the control unit when monitoring that the output of the main equipment power supply is abnormal; the control unit is used for judging the abnormal output of the main equipment power supply according to the received control signal and sending a control command to control the data processing unit to stop data read and write operations; and the data processing unit is used for stopping the data read and write operations according to the control of the control unit. The technical scheme provided by the invention can realize data protection of the external storage equipment, avoid damaging data due to power fail, and prolong the service life of the external storage equipment.

Description

technical field [0001] The invention belongs to the technical field of storage devices, and in particular relates to an external storage device and a power-down protection method thereof. Background technique [0002] U disk, SD card, mobile hard disk and other external storage devices (hereinafter collectively referred to as external storage devices) are becoming more and more popular, and users use and operate these devices more and more frequently. After the external storage device is connected to a data reading and writing device such as a computer or a TV (hereinafter referred to as the main device), the main device supplies power to the external storage device, but the main device may suddenly lose power, resulting in abnormal power output. If the external storage device is performing data read and write operations when the main device suddenly loses power, the possibility of data stored in the external storage device being destroyed will be greatly increased, and even...
