2.3.Deleting Partitions

Actually, before we rush headlong into formatting, 

let’s take a look at deleting partitions. It’s not difficult

at all - but it can cause you to lose data if you delete 

the wrong drive or partition.

Let’s look at FDISK’s Delete menu 

From FDISK’s main menu, choose Option 2.
You should then see the menu below.

-------------------------------------------------------------
Delete DOS Partition or Logical DOS Drive

Current fixed disk drive: 1

Choose one of the following:

1.Delete Primary DOS Partition
2.Delete Extended DOS Partition
3.Delete Logical DOS Drive(s) in the Extended DOS Partition
4.Delete Non-DOS Partition



Enter choice: [1]




Press ESC to return to FDISK Options
-------------------------------------------------------------

As you can see, there are several options for deleting things.
The first one is used to delete Primary DOS Partitions.
The second is used to delete Extended DOS Partitions.
You cannot delete an Extended DOS Partition while there are
still Logical DOS Drives within it.
The third option is use to delete those Logical DOS Drives
I just mentioned. And the last option is used to delete
partitions created by operating systems.
Special Note: THIS DOESN’T ALWAYS WORK! You may need
to use a third-party partitioning tool such as Delpart.exe,
Symantec’s GDISK or Partition Magic.


Now let’s delete some partitions!
Here’s a sample system configuration:

------------------------------------------------------------

Change Current Fixed Disk Drive

Disk    Drv    Mbytes    Free    Usage
  1            19571              100%
         C:     6150
         D:    13421
  2            19564        8     100%
         E:    19556
  3            13037        8     100%
         F:    11037
                1992


(1 Mbyte = 1048576 Bytes)
Enter Fixed Disk Drive Number (1-3). . . . . . . . . . [1]

Press ESC to return to FDISK Options
------------------------------------------------------------

In this example, you can see that Disk 1 has two partitions
on it - Drive C and Drive D. We’re going to delete Drive D:
Please note - by deleting this partition, Drive E will
become D and Drive F will become E.

Using Option 4 from the main menu, we can get a bit more
information about the drive.

------------------------------------------------------------

Display Partition Information

Current Fixed Disk Drive: 1

Partition  Status  Type    Volume Label Mbytes System Usage
 C: 1         A    PRI DOS               6150   FAT32   31%
    2              EXT DOS              13421           69%


Total disk space 19571 Bytes (1 Mbyte = 1048576 bytes)

The Extended DOS Partition contains Logical DOS Drives.
Do you want to display the logical drive information (Y/N)?[Y]



Press ESC to return to FDISK Options
------------------------------------------------------------


We see here that Disk 1 is 19.5 GB in size, it has a 6 GB
Primary DOS Partition using Fat-32 and it has an Extended DOS
Partition which is 13.4 GB in size. If we wish, we can see
more info about this partition.

Anyhow...
From the main menu we’ll choose Option 2 to enter the Delete
menu, then Option 3 to delete a Logical DOS Drive.
Here’s what we see:

------------------------------------------------------------

Delete Logical DOS Drive(s) in the Extended DOS Partition

Drv  Volume Label  Mbytes  System  Usage
 D:                13421  FAT32     100%







Total Extended DOS Partition size is 13421 Mbytes

WARNING: Data in a deleted Logical DOS Drive will be lost.
What drive do you want to delete. . . . . . . . . . . . ? [ ]


Press ESC to return to FDISK Options
------------------------------------------------------------


At the prompt, we enter the letter of the drive we wish
to delete.  Some people like to name their partitions -
for example, it’s not unusual to have Drive C: labeled
as OS and one of the Logical DOS Drives as GAMES or DATA.
If the drive has a volume label we’ll have to type that
in as part of the confirmation that we really, really
want to delete this drive. Then we’ll be asked again
if we wanted to delete the Logical DOS Drive.
If we say yes, FDISK will at long last delete the drive.

Okay. We’ve gotten rid of the Logical DOS Drive,
but we still have the Extended DOS Partition.  To get
rid of that, we return once again to the Delete menu
and this time choose to delete the Extended DOS
Partition. This partition doesn’t get a label, so we
should just be able to delete it after being prompted
that we really want to do so. If there were any other
Logical DOS Drives in this partition, we would be unable
to delete the partition until we deleted the drives.

Right. You’ve learned how to delete partitions.
It’s time we finally got around to formatting.
