FDISK + Partitioning the Hard DiskServes as a menu-driven hard disk preparation program.
VERSION
PC-DOS 2.0+ (revised in 3.3)
MS-DOS equivalent: FDISK
TYPE
External
SYNTAX
[d:][path] FDISK
OPTIONS
[d:][path] Specifies the drive letter and path that
contain the FDISK command file.
You will see the following options on the FDISK menu:
1 Create DOS Partition
2 Change Active Partition
3 Delete DOS Partition
4 Display Partition Data
5 Select Next Fixed Disk Drive
You must use the FDISK command each time you start up a new
hard disk. It establishes the physical area of the disk that is
used by DOS (partitions the disk).
MESSAGES
All logical drives deleted in the
Extended DOS partition
No more logical drives are defined in the extended DOS partition.
You can delete the extended DOS partition if you no longer need
it for additional drives.
Cannot create extended DOS partition
without primary DOS partition on disk 1
You cannot have an extended DOS partition on disk 1 unless you
also have a primary DOS partition. Create a primary DOS partition
using FDISK, and leave sufficient space for the extended
partition.
Cannot delete extended DOS partition
while logical drives exist
As long as logical drives are defined in an extended DOS
partition, you cannot delete it. Use FDISK to delete all logical
drives in the extended partition.
Cannot run FDISK with network loaded
You cannot run this command while the network program is loaded.
Restart the machine and then run FDISK.
DOS partition already exists
DOS has already been set up on this hard disk.
Error reading fixed disk
FDISK was unable to read the hard disk. Reissue the FDISK
command. If the error message persists, consult your IBM Guide to
Operations (the Problem Determination section) or your dealer.
Extended DOS partition already exists
Use option 4 of the FDISK menu to display information about the
partitions that are already on the hard disk.
No Extended DOS partition to delete
Use option 4 of the FDISK menu to display information about the
partitions that are already on the hard disk.
No fixed disks present
Your system either does not have a hard disk, has a hard disk in
an expansion unit that is not turned on, or has an improperly
installed hard disk. Check to see that the expansion unit is
turned on, or reinstall your hard disk.
No logical drives defined
There are no logical drives that have been defined in the
extended DOS partition. Use FDISK to create a logical drive, and
then format the newly created drive by using the FORMAT command.
No partitions defined
There are no partitions that have been defined in the extended
DOS partition. Use FDISK to create a primary DOS partition, and
then format the drive by using the FORMAT command.
No partitions to delete
Use option 4 of the FDISK menu to display information about the
partitions that are already on the hard disk.
No partitions to make active
Use the Create DOS Partition option (1) to create a partition;
then use the Change Active Partition option (2) to make it
active.
No Primary DOS partition to delete
Use option 4 of the FDISK menu to display information about the
partitions that are already on the hard disk.
No space for a xxxx cylinder partition
You have entered a cylinder size that is larger than the amount
of free space. Enter a smaller number.
No space to create a DOS partition
Remove the existing partition or reduce its size. Then run FDISK
again.
No space to create logical drive
Use FDISK to delete an existing logical drive; then run FDISK
again to create the new logical drive.
Only non-bootable partitions exist
FDISK was requested to change the active partition, but none of
the other partitions can boot from the hard disk. Create a
bootable partition, such as the primary DOS partition.
Only partitions on Disk 1 can be
made active
The system uses the first hard disk to boot from. Use the FDISK
command to make a partition active so that the hard disk will
boot the system.
Partition selected (#) is not bootable,
active partition not changed
Use FDISK to select a bootable partition to be active.
Primary DOS partition already exists
You can have only one primary DOS partition on a hard disk. Use
option 4 on the FDISK menu to display information about the
partitions that are already on the hard disk.
NOTES
With FDISK you can choose to use the entire disk for DOS, or
you can allocate space on the hard disk to other operating
systems. In version 3.3 of PC-DOS you can also create extended
DOS partitions that can be further subdivided into logical
drives, such as drives D and E.
After you have used the FDISK command, use the SELECT
command to format the hard disk, copy the DOS commands from the
DOS disk to the hard disk, and specify the keyboard layout and
date/time formats you want to use. You can then boot directly
from the hard disk. lternatively, you can format the disk with
the FORMAT C:V command to transfer the system files and give a
volume label; then use the COPY command to copy the DOS commands
from the DOS floppy disk.)
If you are creating multiple partitions, you will be
prompted to specify the size of the partition; press Return to
accept the default, or enter any number that is less than the
maximum cylinder size you will see displayed at the bottom of the
screen. Likewise, when you are prompted for a starting cylinder
number, press Return for the default, or enter a cylinder number
based on the information displayed on the screen. For example, if
you chose 25 cylinders less than the maximum, you can start the
partition 25 cylinders further from the starting number on the
screen.
If you are creating multiple partitions and wish to make the
one you just created the active partition, you must select option
2. Option 3 deletes the DOS partition. If you select it, you will
be prompted through a process that deletes the DOS partition
along with all data files and programs it contains. Option 4
allows you to view that status of the partitions that exist on
the hard disk. Option 5 is designed to be used if you have a
second hard disk. It allows you to switch to that drive to
perform FDISK operations.
