Repairing method and device of data partition, and terminal

The invention provides a repairing method and device of a data partition, and a terminal. The repairing method of the data partition is characterized in that data stored in the data partition of the terminal is backed up in other partitions of the terminal, so that the data partition of the terminal is subjected to a formatting operation if a detection result shows that the data partition of the terminal is exceptional in a terminal starting process, and therefore, the data stored in other partitions of the terminal is copied to the data partition, which is subjected to the formatting operation, of the terminal. The technical scheme can be adopted to prevent data in the data partition of the terminal from losing when the data partition of the terminal is repaired, and the repairing reliability of the data partition of the terminal is improved. 本发明提供种数据分区的修复方法、装置及终端。本发明的数据分区的修复方法，通过将终端的数据分区存储的数据备份在所述终端的其他分区，从而，在所述终端的启动过程中，若检测到所述终端的数据分区出现异常，对所述终端的数据分区执行格式化操作；进而，将所述终端的其他分区存储的所述数据拷贝至经过格式化操作的所述终端的数据分区。采用本发明的技术方案，能
