Use Table 4.5 to determine what the FDISK total disk space figure is
telling you about your system.

X Value1 Y Value2 Drive Size Underlying Cause
>504MB =504MB >504MB Binary Drive was prepared with LBA
/FDISK (528MB mode enabled, but LBA

in this chapter.

1. The X value appears only when a drive has already been FDISKed.
2. The Y value appears on any drive being viewed through FDISK, whether the FDISK process has
been completed or not.
For more information about using FDISK, see the section “Using
FDISK” later in this chapter.
Getting LBA and Extended Int13h Support for Your
System
If your computer is incapable of detecting the full capacity of your
hard disk or locks up after you install the hard drive, your BIOS is
not compatible with your hard drive. Use Table 4.6 to determine
the causes and solutions that will help you get full capacity from
your new hard disk with maximum safety.
