At the factory, the Maxtor D540X-4K 20.4/40.0/60.0/80.0 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.
