<P>PROBLEM TO BE SOLVED: To provide a file system management apparatus for quickly booting a system stored in a storage medium even when data required for booting the system are rewritten. <P>SOLUTION: When a write access to data required for booting the system is generated (S1, S2), a portion corresponding to the data to be accessed in an HDD is updated (S3) and data with the updated result reflected therein are copied to a flash memory (high-speed storage medium) (S5, S7). When the data required for booting the system are rewritten and the location of the data in the HDD is changed (S4, S6), an address or the like of the new data is calculated, an address in an address management table is rewritten on the basis of the calculated result, and then the updated data are copied to the flash memory. <P>COPYRIGHT: (C)2009,JPO&INPIT |
