Press ESC to return to the FDISK options. Create an Extended DOS Partition by selecting option 1 from
the main menu and option 2 from the second menu. (Both menus shown above.)
Note: The Maximum Capacity shows only 8455 MB instead of 9130 MB. This is because the BIOS of
some systems recognizes a Megabyte as 1,048,576 bytes (binary). Drive manufacturers recognize a
Megabyte as 1,000,000 bytes (decimal). The capacities are the same in actual number of bytes.
After creating the Extended DOS Partition, press ESC to return to the FDISK main menu. Select option
1 to create a Logical DOS Drive, then option 3 to create a Logical DOS Drive in an Extended Partition.
Press ESC to return to FDISK and press ESC again to restart the system. You must restart the system
for the partitions to be recognized.
Step 9: Formatting
The drive will need to be formatted before an operating system can be loaded. Format the Primary
partition and any Extended partitions that have been made.
After booting from a bootable diskette, run FDISK, option 4 to display the partition information. This is
helpful to review drive letter assignments. Note the drive letters to ensure proper formatting.
Press ESC to return to the main menu and exit FDISK. At the A:\ prompt type format x: /s
(where x is the drive letter). The /s option will make your hard drive bootable by copying the system files
to the hard drive. If you do not want this drive to be bootable, do not use the /s command. You will see
the following warning:
