FORMATTED CAPACITY

At the factory, the Maxtor Atlas 10K V receives 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, will result in less capacity than the physical
capacity shown.
