Abstract
A method and system for storing file system state information within sectors of the file system. File system information includes pointers to top-level file system structures, such as free space bitmaps, a bad block list, a directory block band, and a root directory. The file system state information is classified into two groups: frequently-updated information and infrequently-updated information. The two groups are stored on separate sectors in order to minimize write operations performed on the infrequently-updated information and thereby reduce the risk of the infrequently-updated information being corrupted.
