一种嵌入式系统中FAT文件系统修复方法,包括以下步骤:1),检查操作系统修改两张FAT表是否一致,如果不一致,使用第一张FAT表来覆盖第二张FAT表;2)遍历FAT文件系统所有文件,采用分段读取的方法,在分段读取时记录FAT表段的起始项和结尾项对应在整个FAT表中的顺序号,依此来判断当前读取的簇对对应的FAT项是否在已经读取的...
Chained allocation: allocation is on an individual block basis.Each block contains a pointer to the next block in the chain. Indexed allocation: the file allocation table contains a separate one-level index for each file;the index has one entry for each portion allocated to the file. 连续分...
fat, or file allocation table, is a file system used by various operating systems, notably older versions of windows. it organizes and manages data on storage devices like hard drives and usb flash drives. fat divides storage space into clusters, each holding a fixed number of sectors, and ...
Fille allocation table history and versions The FAT file system got its start with the introduction ofMS-DOS, or Microsoft Disk Operating System, and is still in use today, but it has evolved over the years to accommodate growing data volumes. During that time, there have been multiple versio...
