Parameter Data Format

SSEC (soft sectoring)

When this bit is "1," it indicates that the data formatting method on the disk media is "soft sectoring." However, since the HDD uses only the "hard sectoring" method (refer to previously shown item b), this bit is disregarded. Furthermore, it is impossible to change this parameter.

HSEC (hard sectoring)

When this bit is "1," it indicates that the data formatting method on the disk media is "hard sectoring." However, since the HDD uses only the "hard sectoring" method, this bit is disregarded. Furthermore, it is impossible to change this parameter.

RMB (removable medium)

When this bit is "1," it indicates that the storage media of the disk drive can be replaced. When this bit is "0," it indicates that the storage media is fixed. However, since the HDD has a fixed media, this bit is disregarded. Furthermore, it is impossible to change this parameter.

SURF (surface addressing)

When this bit is "1," it indicates that after logical data block address allocation is performed over all the sectors in order on the same memory surface (same head), it is proceeding to the next memory surface (next head) after all the sectors have been done. When this bit is "0," it indicates that after logical data block address allocation is performed over all the sectors in order in the same cylinder (all heads), it is proceeding to the next cylinder. In the HDD, only the latter type of addressing is possible, so this bit is disregarded. It is also impossible to change this parameter.
