Semiconductor memory card access apparatus, a computer-readable recording medium, an initialization method, and a semiconductor memory card

An initialization method for initializing a computer to perform file access on a semiconductor memory card that has a memory area comprising a plurality of sectors, by managing data in each group of 2j sectors (j being 0 or a positive integer) as a cluster, and managing one or more clusters as a file, each group of 2i consecutive sectors in the memory area forming a block (i being 0 or a positive integer), a block being a smallest unit on which data erasure can be performed, said initialization method comprising:

• calculating a size of volume management information including a master boot record, a partition table, partition boot sector information, a file allocation table, and a root directory entry;
• reserving a first area having two or more blocks, a second area, and a backup area;
• and
• recording the master boot record and the partition table in a first sector of a first block of the first area, skipping a predetermined number of sectors and then recording the partition boot sector information, the file allocation table, and the root directory entry in subsequent sectors in order to align an end of the first area with an end of the root directory entry, recording user data in the second area, and recording attribute information of the file in the backup area in units of blocks.

A recording medium storing a program in a computer-readable format for initializing a computer to have file access performed on a semiconductor memory card that has a memory area comprising a plurality of sectors, by managing data in each group of 2j sectors (j being 0 or a positive integer) as a cluster, and managing one or more clusters as a file, each group of 2i consecutive sectors in the memory area forming a block (i being 0 or a positive integer), a block being a smallest unit on which data erasure can be performed, said recording medium being operable to cause the computer to:

• calculate a size of volume management information including a master boot record, a partition table, partition boot sector information, a file allocation table, and a root directory entry;
• reserve a first area having two or more blocks, a second area, and a backup area;
• and
• record the master boot record and the partition table in a first sector of a first block of the first area, skip a predetermined number of sectors and then record the partition boot sector information, the file allocation table, and the root directory entry in subsequent sectors in order to align an end of the first area with an end of the root directory entry, record user data in the second area, and record attribute information of the file in the backup area in units of blocks.
