3.1.5Format capacity

The size of the usable area for storing user data on the IDD (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.3 lists examples of the format capacity when the typical logical data block length and the default spare area are used. The following is the general formula to calculate the format capacity.

[Number of sectors of each zone] = [number of sectors per track × number of tracks (heads) – number of alternate spare sectors per cylinder] × [number of cylinders in the zone]

[Formatted capacity] = [total of sectors of all zones] – [number of sectors per track in last zone × number of tracks (heads) × number of alternate cylinders] ÷ [number of physical sectors in logical block] × [logical data block length]

The following formula must be used when the number of logical data blocks are specified with the parameter in the MODE SELECT or MODE SELECT EXTENDED command.

[Format capacity] = [logical data block length] × [number of logical data blocks]

The logical data block length, the maximum logical block address, and the number of the logical data blocks can be read out by a READ CAPACITY, MODE SENSE, or MODE SENSE EXTENDED command after initializing the disk medium.
