How to use the Disk Utility for disk management

Disk Utility is a built-in tool on macOS that allows users to manage and troubleshoot their storage devices. From formatting and partitioning drives to repairing disk errors, this tutorial will guide you through the steps of using Disk Utility effectively for disk management.

Step 1: Opening Disk Utility

  1. Go to the "Applications" folder on your Mac and open the "Utilities" folder.
  2. Locate and open the "Disk Utility" application. You can also use Spotlight search by pressing Command + Spacebar and typing "Disk Utility".
  3. The Disk Utility window will now open, showcasing a list of storage devices connected to your Mac.

Step 2: Identifying and Selecting the Disk

  1. In the Disk Utility window, you will see a list of disks and volumes on the left-hand side.
  2. Disks are typically labeled with their manufacturers' names and sizes, while volumes depict the individual partitions on each disk.
  3. Identify the disk you want to manage from the list and click on it. Disk Utility will display detailed information about the selected disk.

Step 3: Formatting a Disk

  1. Note: Formatting a disk erases all data stored on it. Make sure to back up important data before proceeding.
  2. Select the disk you want to format from the list on the left.
  3. Click on the "Erase" button at the top of the Disk Utility window.
  4. A dialog box will appear, allowing you to specify the format, name, and scheme for the disk.
    • Format: Choose a format based on your requirements. "Mac OS Extended" (Journaled) is commonly used for macOS operating systems.
    • Name: Enter a name for the disk.
    • Scheme: Select a scheme, such as "GUID Partition Map" for Intel-based Macs.
  5. Once you have made your selections, click on the "Erase" button to initiate the formatting process.
  6. Disk Utility will display a progress bar indicating the status of the formatting. Once completed, the disk will be ready for use.

Step 4: Partitioning a Disk

  1. Note: Partitioning a disk divides it into multiple sections, each behaving like a separate disk. Data loss may occur during the partitioning process. Back up important data before proceeding.
  2. Select the disk you want to partition from the list on the left.
  3. Click on the "Partition" button at the top of the Disk Utility window.
  4. A new dialog box will appear, displaying a graphical representation of the disk and its current partitions.
  5. To create a new partition, click on the "+" button.
  6. Adjust the size of the partition by dragging its edge or entering a specific size in the provided field.
  7. Optionally, you can set the partition format and name by selecting each partition and modifying the corresponding options.
  8. Repeat steps 5-7 if you want to create additional partitions.
  9. Once you have set up the partitions according to your preferences, click on the "Apply" button to apply the changes.
  10. Disk Utility will display a warning message, notifying you about potential data loss. Click on "Partition" to proceed.
  11. The disk partitioning process will begin, and Disk Utility will show a progress bar. Once completed, the disk will be partitioned as specified.

Step 5: Repairing a Disk

  1. Open Disk Utility and select the disk you want to repair from the list on the left.
  2. Click on the "First Aid" button at the top of the Disk Utility window.
  3. A new window will appear, listing the available repair options.
  4. Click on the "Run" button next to the repair option you wish to perform (e.g., "First Aid" to repair disk errors).
  5. Disk Utility will analyze the disk and repair any identified issues. The progress and results will be displayed in the window.
  6. Once the repair process is complete, Disk Utility will indicate whether the disk was successfully repaired or if further action is necessary.
