Attorney, Agent or FirmInternational ClassG06F 012/00AbstractA 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 system classifies the file system state information into two groups: frequently-updated information and infrequently-updated information. The two groups are stored on separate sectors. Thus, the frequently updated information can be updated without rewriting the infrequently updated information. Because the infrequently updated information is not rewritten, the risk of this information being corrupted is significantly reduced.Other References
