Ways to Use Disk Utility in macOS

Disk Utility has a lot of different disk management tools, such as the ability to find and fix a broken drive, erase your drive, divide it into partitions, and a lot more. You can use Disk Utility in four main ways, which you can read about below:

1. Use the Finder to Open Disk Utility:

Step 1. Start macOS and open the Finder.

Step 2. Go to "Go" and then pick "Utilities" on macOS.

3. Use Disk Utility to Check for External Drive Faults:

You can use Disk Utility's "First Aid" tool to determine what's wrong with an external drive connected to your Mac.As its name suggests, the First Aid tool checks the drive for problems and fixes them if it finds any. However, this method can't fix problems with the hard drive inside your Mac.

To do that, you'll need to start up your Mac in Recovery Mode for now. Here's how to use First Aid on your Mac to check an external drive:

  • Go to your Mac and open Disk Utility. You can do this by starting the Finder, going to Applications > Utilities, or using Spotlight to look for it.
  • From the left, choose the drive that is giving you trouble. To see all your devices, click Show All Devices in the menu above View.
  • Press on "First Aid."
  • Disk Utility will check the drive volume for mistakes and fix them if it finds any. Press "Run."

4.Disk Utility to Repair Your Mac's Startup Disk:

That's not all. You can also fix problems by running First Aid on your starting drive. Otherwise, Disk Utility won't be able to fix your Mac's starting drive unless you start macOS in Recovery Mode. If you have a Mac, starting up your Mac in Recovery Mode is slightly different.

Turn off your Apple hardware Mac and hold down the Power button while it boots up. If you have an Intel Mac, restart it and press Command + R at the same time. So that you can fix your starting drive, start up macOS Recovery and do the following:

  1. The macOS Utilities screen should show up once you're in macOS Recovery. Pick up Disk Utility.
  2. Select the hard drive you want to fix from the list, then click "First Aid."
  3. The same thing will happen: Disk Utility will check the drive and try to fix the problem. It could take a while.

Disk Utility's Features

Disk Utility is a simple program that can be found in the Utilities folder. Let's look at its most important parts:

  • Disk List: This main panel shows all the linked internal and external storage devices. It details each disk, like what kind of disk it is (HDD or S.S.D.), how much space it has, and what file system it uses.
  • First Aid: You can check and fix disk rights and directory structures with this important tool. Users or programs can only view certain files with the right permissions. These permissions can become corrupted over time, which can cause entry problems. First Aid in Disk Utility can find these problems and fix them.
  • Erase: This feature lets you erase (format) a disk, deleting all the data and making it ready to be used. This is very important when setting up a new drive, restarting macOS, or safely deleting private data. Disk Utility lets you erase data in several ways, and you can pick the amount of security (number of write passes) that works best for you.
  • Partition: This powerful tool lets you change the layout of your disk by making, resizing, or deleting partitions. Partitioning lets you set aside different parts of your storage for different uses. For example, if you use Boot Camp to install Windows, you could have a separate disk.
  • Restore: After making one, you can recover a disk image (a full, compressed copy of a disk) and transfer it to another disk using Disk Utility. That can be used to make backups or copies of a certain system setup.
  • S.M.A.R.T. Status (Solid State Drives only): Disk Utility can show the Self-Monitoring, Analysis, and Reporting Technology state for S.S.D.s, which tells you about the drive's health and lifespan.

Conclusion:

Disk Utility is important for keeping your Mac's storage in good condition. It has many features for all levels of users, from basic jobs like erasing and formatting disks to more complex ones. Understanding and using these features will ensure the disk works well and lasts long.

Disk Utility gives you the tools to keep your Mac's storage running easily and efficiently, whether doing simple maintenance or fixing more complicated problems. Anyone who wants to keep their Mac healthy, reliable, and running must know how to use Disk Utility.
