摘要
为了维护嵌入式文件系统的一致性,经过对大量的因为系统崩溃而使文件系统不一致情形分析后发现,主要原因在于发生故障时导致文件系统出现了逻辑上的错误。基于对FAT16文件系统,提出了修改这些错误的一种数据恢复机制。通过对FAT16相应数据的一遍扫描,填充有关位图,修改相应的错误,以维护系统的一致性,该机制同时具有快速的特点。
In order to maintain the consistency of embedded file system,mainly due to the failure of file system,it has led to the erroneous logic after the analysis of collapse of the system and lead to large file system where found inconsistencies.Based on FAT16,changing to these errors as a mechanism for data recovery is proposed.Through scanning the corresponding data of the FAT16 one time,filling of the bitmaps and correcting the corresponding errors,this mechanism has the characteristics of rapid at the same time.
