Abstract

The invention discloses a data writing storage error recovery method and system, terminal equipment and a computer storage medium. The method comprises the following steps: analyzing to-be-stored datafrom a received data storage command, and transmitting the to-be-stored data to a preset storage medium for writing storage; if a writing error prompt fed back by the storage medium is received, determining a to-be-recovered data identifier pointed by the writing error prompt, extracting exclusive OR results of the odd page data and the even page data written and stored by the storage medium, andon the basis of the to-be-recovered data identifier, performing exclusive-OR operation by utilizing the exclusive-OR results of the odd page data and the even page data to obtain recovered data. Thelimitation of data recovery is avoided, the data which is not successfully stored due to the programming error of the storage medium can be more accurately recovered, the data recovery accuracy is high, and the phenomenon of difference between the recovered solid-state storage data and the source data is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a recovery method, system, terminal equipment and computer storage medium for error reporting in data writing and storage. Background technique [0002] Nowadays, when data is written into solid-state storage devices based on data storage media (such as 3D Nand Flash: a storage product for solid-state storage of data), it is usually unavoidable that programming failures lead to errors in data storage. Phenomenon. [0003] Although there are existing data recovery methods proposed for the above phenomenon, such as recovering part of the data that was reported as an error in the process of writing storage by performing an XOR operation on the entire data, this data recovery method is usually only applicable to data with a small amount of data. In this case, it is used to recover the data reported by the writing error, which has very large limitations, and the above me...
