Abstract

The embodiment of the invention discloses a data recovery method, a data recovery system and a solid state disk. The method is applied to the solid state disk in the data recovery system. The data recovery system further comprises an upper computer. The solid state disk comprises a control unit, a flash memory and a cache memory, and the method comprises the steps of if a data recovery instructionsent by an upper computer is received, reading data in the flash memory into the cache memory; performing error correction processing on data in the cache memory, and sending the data subjected to the error correction processing to the upper computer; repairing the flash memory, and a notification message is sent to the upper computer after repairing is completed; and receiving the data sent by the upper computer, and correspondingly storing the data into a flash memory. By applying the technical scheme provided by the embodiment of the invention, the data in the flash memory is recovered sothat the reliability of the data in the flash memory is ensured. The repair of the flash memory is realized.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a data recovery method, a data recovery system and a solid-state hard disk. Background technique [0002] With the development of network technology, technologies such as big data, cloud computing, and the Internet of Things have emerged, which will generate massive amounts of data and information while bringing convenience to human life. How to properly keep these data is particularly important. [0003] Solid state drives are widely used because of their fast read and write speeds, high performance, and high reliability. However, during the use of the solid-state hard drive, it may be affected by external factors, which may cause storage errors in the flash memory chip of the solid-state hard drive. At this time, the host cannot correctly read the data in the solid-state drive. The error of the flash memory chip can be repaired by formatting the solid state drive, but the d...
