Introduction

In this lab, you will work with disk CLI commands.

Required Resources

• A Windows PC
• An additional partition with an NTFS file system

  Instructions

Part 1:  The chkdsk Command Options

In this part, you will explore the Windows command that allow you to scan and repair disks.

Step 1:  Explore the chkdsk command

1. Open a command prompt.
2. Open the help page the command chkdsk. Enter help chkdsk or chkdsk /? at the prompt to answer the following questions:

Questions:

What is the option to fix errors on the drive?

/F

What is the option to force the volume to dismount first if necessary?

/X

What is the option to locate bad sectors and recover readable information?

/R

3. Enter the chkdsk command to check the C:\ drive with the options from the questions in the previous step.

Question:

What happened? Explain.

Access was denied because you do not have sufficient privileges.

Step 2:  Use the chkdsk command options.

1. Open a Command Prompt window with elevated privileges. Click Start and search for Command Prompt. Within the search results, right-click Command Prompt and select Run as administrator.

2. In the Command Prompt window with elevated privileges, enter the command chkdsk C: /F /X /R to check the status of this drive. Enter y when prompted. Note the change in the prompt.

C:\Windows\system32> chkdsk C: /F /X /R

The type of the file system is NTFS.

Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another

process.  Would you like to schedule this volume to be

checked the next time the system restarts? (Y/N) y

This volume will be checked the next time the system restarts.

Note that the volume will be checked when the system restarts that next time because the volume is in use and it cannot be checked at this time.

Question:

What is the file system of the drive?

Answers will vary. The common file systems available in Windows are FAT, FAT32, and NTFS.

3. A second partition was created in a previous lab. You can perform the chkdsk command on the second partition. The I: drive will be used in this example.

C:\Windows\system32> chkdsk I: /F /X /R

The type of the file system is NTFS.

Volume label is ITEINFO.

Stage 1: Examining basic file system structure …

  256 file records processed.

File verification completed.

  0 large file records processed.

  0 bad file records processed.

<some output omitted>

Part 2:  Create a new partition using DiskPart

In this part, you will shrink the second partition on the hard drive and create a third partition.

Note: Please back up any data from the drives before proceeding in this part. Because a new partition will be created by shrinking a volume and the new partition will be formatted. All data will be erased during the formatting process.

Step 1:  List the disks, partitions, and volume.

1. Using a command prompt with elevated privilege, enter diskpart at the prompt.

C:\Windows\system32> diskpart

Microsoft DiskPart version 10.0.17763.1

Copyright (C) Microsoft Corporation.

On computer: DESKTOP-PUU52R2

DISKPART>

2. Notice the prompt indicated that you are in the diskpart utility. Enter help at the DISKPART> prompt to list the available commands within the diskpart utility. You can also use the help command anytime while you are in the diskpart utility. For example, enter help list disk at the prompt to view more information about the list disk command.

DISKPART> help list disk

    Displays a list of disks.

Syntax:  LIST DISK

    Displays a list of disks and information about them, such as their

    size, amount of available free space, whether the disk is a basic

    or dynamic disk, and whether the disk uses the master boot record

    (MBR) or GUID partition table (GPT) partition style. The disk marked

    with an asterisk (*) has focus.

3. Enter list disk at the DISKPART> prompt to list all the disk in the PC.

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt

  ——–  ————-  ——-  ——-  —  —

  Disk 0    Online           50 GB  1024 KB

Question:

Enter list partition to list all the partitions on the disk. How partitions are on the disk?

Answer may vary.

4. Enter list partition command to list the partitions on the disk. Note: If you only have 1 disk, the disk is selected by default. If you have more than 1 disk in your PC as listed in the list disk command, you will need to select the desired disk. If you are interested in disk 0, enter select disk 0.

DISKPART> select disk 0

Disk 0 is now the selected disk.

5. Enter list partition to list all the partition on the selected disk.

DISKPART> list partition

  Volume 4     D   SecondDisk   NTFS   Partition   5117 MB  Healthy

7. Select the volume that will be used to create a new partition in the next step.

DISKPART> select volume 3

Volume 3 is the selected volume.

Step 2:  Shrink a volume.

1. Review the shrink command. Enter help shrink at the DISKPART prompt.

DISKPART> help shrink

    Reduces the size of the volume with focus by the specified amount. Makes

    free disk space available from unused space at the end of the volume.

Syntax:  SHRINK [DESIRED=<N>] [MINIMUM=<N>] [NOWAIT] [NOERR]

        SHRINK QUERYMAX [NOERR]

<some output omitted>

Question:

What option is used to determine the maximum number of bytes that the volume can be shrink by?

QUERYMAX

2. Use the shrink command with the option querymax to determine the maximum number of bytes that the volume can be shrink by.

Question:

What is the maximum number of reclaimable bytes?

Answer will vary.

3. Enter shrink desired=500 to reduce the size of volume by 500 megabytes.

DISKPART> shrink desired=500

The maximum number of reclaimable bytes is:  500 MB

Step 3:  Create a new partition.

In the previous step, you have create 973 MB free space on the disk. In this step, you will create a primary partition with 500 MB with an NTFS file system.

1. Enter create partition primary at the DISKPART prompt.

DISKPART> create partition primary

DiskPart succeeded in creating the specified partition.

Note: If there are already 3 primary partitions, you will need to create logical partition, instead of primary partitions.

DISKPART> create partition extended

DISKPART> create partition logical

2. List the partition to verify that you have created a new partition. Notice the asterisk (*) next to partition 4 to indicate the partition is currently selected.

DISKPART> list partition
