Page 38

The number of spare sectors per cell can be specified from 0 to 200. The default for the spare sectors number is 200.

Cell

Note: This drive manages alternate spare areas for each cell, which is a set of cylinders. One cell consists of 27 cylinders.

Figure 3.2 Spare area in cell

An alternate cylinder is used when spare sectors in a cell are used up or 0 is specified as the number of spare sectors in a cell. 1 cylinder at the end of each zone of the user space is allocated as alternate cylinders as shown in Figure 3.3.

The user space and the system space share the alternate cylinders.

Zone

Note: The number of alternate cylinders can not be changed.
