FORMATTED CAPACITY
At the factory, the Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT
hard disk drives receive a low-level format that creates the actual tracks and sectors
on the drive. Table 4-2 shows the capacity resulting from this process. Formatting
done at the user level, for operation with DOS, UNIX, or other operating systems,
may result in less capacity than the physical capacity shown in Table 4-2.
