HSEC (hard sectoring)
When this bit is "1," it indicates that the data formatting method on the disk media is "hard
sectoring."
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 IDD 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 IDD, only the
latter type of addressing is possible, so this bit is disregarded. It is also impossible to change
this parameter.
