Disk Utility is an app that comes with your Mac. It’s in the Utilities folder, which is in the Applications folder. However, with Spotlight, which you activate with the urgent Command + Spacebar, it’s easy to find. Here’s what you might be able to use Disk Utility for:

  • Disk Utility is used to erase, format, or handle internal hard drives and external storage devices.
  • Disk Utility can also be used to add and handle volumes, or to partition your date.
  • Disk Utility is useful when working with RAID devices. Combining multiple hard drives into a RAID set that acts as a single hard drive can improve efficiency, reliability, and storage space.
  • Disk Utility lets you create a disk image of files that you really want to transfer, archive, or retransfer to another computer.
  • Disk Utility is used to diagnose and repair problems with a disk or defective volume.

Disk Utility was redesigned in Mac OS X El Capitan when it was redesigned and many of the options were expanded or removed.

How to create a bootable macOS High Sierra installer drive Put the macOS High Sierra installer on an external USB thumb drive or hard drive and use it to install the operating system on a Mac.

May 01, 2020  Recently updated to high sierra on an old mac, (yes I am that behind with updates!), now it won’t let me access a Samsung Hard drive i used to use. It won’t mount using disk utility. I can see it using the Terminal and have ejected it like you said, however even though it says ejected, and the light on the hard drive turns off, it is still. Currently, if you only have a Mac computer with macOS High Sierra or above and couldn't find a Windows computer to use our Windows version, you can still try to install and run Mac OS X 10.12 or 10.11 on an external hard drive to make M4VGear work under old version of Mac OSX.

Thanks to the new file format that Apple introduced, there are some changes in macOS High Sierra: APFS (more on this below).

Why Use Disk Utility?

You may want to use Disk Utility when you familiarize yourself with the next one:

Your computer won’t start. (Read: Repair a Mac That Won’t Turn On.)

An external system does not work. (Read: How to Insert an External Drive That Doesn’t Appear on a Mac.)

  • Your apps will stop unexpectedly.
  • You have a broken file.
  • You should mount, unmount, or eject a disc.
  • You should change the file system, for example to allow or disable journaling.
  • You assume that, together with your startup disk, this is a disadvantage.
  • You should restore a broken hard drive.
  • For deleting, formatting or partitioning a hard drive.
  • Disk Utility was used to confirm and restore permissions. However, this has not been decisive since El Capitan.

Here’s how to find out if your hard drive is faulty with Disk Utility

If you believe that the hard drive in your Mac or external storage system is a disadvantage, you may be able to use the first aid feature in Disk Utility to check.

The first aid feature in Disk Utility does a series of checks. If it detects a disadvantage along with your hard drive, it will be repaired.

Note: The Disk Utility has been slightly redesigned in OS X El Capitan. As a result, the best way to improve a hard drive has changed significantly. The steps to be performed depend on the MacOS model used. We are assuming that you have been using a model that is newer than El Capitan since this model was introduced by Mac OS X in September 2015.

To run First Aid on your Mac to find a disadvantage with your drive:

  1. Open the disk utility.
  2. Select your system with which you have points in the sidebar.
  3. Click First Aid.
  4. Disk Utility checks the partition game cards on the disk and lots. If you only provide first aid for a lot, Disk Utility will only check the contents of that lot.

If the hard drive is found to be at a disadvantage, the hard disk utility will attempt to repair it.

If Disk Utility tells you that the disk or volume will fail, restart and change it. Disk Utility cannot fix it.

If the disk utility detects that the disk is OK, it means that the disk has no disadvantage.

Repair a hard drive with Disk Utility

How you recover a hard drive depends on whether it is your Mac’s startup disk (the disk your Mac is running on, the location of your work system), or a person’s disk connected to your Mac. If it is your startup disk, continue with the next section.

  1. Open Disk Utility (Applications> Utilities or Disk Utility in the cmd + section).
  2. Select the amount for which you need to provide first aid. This can be an external tedious drive (if it’s your personal Mac drive, you’ll need to skip to the next part).
  3. Click First Aid.
  4. Click on Run. This starts the review and recovery course from.
  5. When Disk Utility is running, checks are performed and you see a drop-down record with the status. You can click the triangle on the back for more information.
  6. If no errors are found, you’ll see an inexperienced check mark at the top of the drop-down list.
  7. If errors occur, Disk Utility tries to repair them. (In older versions you had to select Repair Disk manually).

If Disk Utility cannot restore the disk or think the disk is faulty, you may be warned. If so, update your files earlier than it’s too late. Read this article on backing up your Mac.

This may come in handy: restore and delete files from a bad drive, SSD, or external drive.

How to restore your boot disk / boot disk using Disk Utility

You can run first aid on your startup disk as described above. However, if the disk utility detects errors, no attempt is made to repair them.

If you want to restore your Mac’s startup disk (the startup amount), you may not be able to do so because Disk Utility cannot restore the amount provided (the amount each part is working on). In older versions of the hard disk utility, the selection “Repair hard disk” is grayed out.

In this case, you want to start your Mac in recovery mode and restore the hard drive from the hard drive. This means there will be issues with the amount of Recovery HD created when pasting macOS. (Note that problems with a Fusion drive are even more complicated.)

  1. To start in recovery mode, press cmd + R when you start up your Mac. We have a detailed tutorial on how to use recovery mode here.
  2. When your Mac boots up, a utility screen will appear. Choose Disk Utility.
  3. Select the hard drive you want to improve from the menu and click First Aid. As above, Disk Utility does its checks and checks if it can be repaired if it can.
  4. The recovery course from could take a while.

How to restore hard drive permissions

When Apple launched El Capitan in 2015, hard drive permissions could no longer be restored.

Deleting the function means in all likelihood that the restoration of permissions has not been completed properly.

It remains feasible to restore permissions with Terminal. However, we will not go into this here as we are following Apple and assume that this is of no use and will probably cause further problems.

However, if you are using Mac OS X Yosemite or earlier and a file’s permissions are not set correctly, a software program that uses the file may not work properly. If so, do the following to correct the permissions:

  1. Open Disk Utility in the Utilities folder of your application folder.
  2. Select the boot disk from the volume record.
  3. Click the First Aid tab.
  4. Click Check Disk Permissions to check the permissions. Click Restore Disk Permissions to restore the permissions.

How to create a disc image using the Disk Utility

Disk Utility can create a disk image of the contents of a folder, which you can then move to another Mac, archive, or other non-folder location.

This is comparable to compressing the folder into a zip archive. The advantage, however, is that not only can you use disk impression to save space, but you can also benefit from Apple encoding for the disk image.

Follow the steps below to create a disk image using Disk Utility.

Format a hard drive using Disk Utility

There are several reasons why you need to format a hard drive. You may want to delete your startup disk so that you can install OS X in a timely manner. You choose to encrypt an external storage disk that you only use for your work, or you choose a partition for Windows or another model of the Mac operating system.

Here is a step-by-step guide to formatting a drive on a Mac.

Troubleshoot an external drive

Partition a hard drive

You may want to partition a hard drive when you need to install a number of work techniques. How you partition depends on whether you’re using High Sierra or a previous model of macOS or Mac OS X. To partition a hard drive:

The macOS Sierra is a wonderful operating system - and easily the best for all Apple computers and laptops. If you have a Mac, then you probably cannot wait to get your hands on the Sierra - provided your system supports it. However, even if your Mac does support Sierra, there may be a few reasons as to why you may not be able to install it on your hard disk.

For starters, it takes around 8GB of storage space. While that is the minimum recommended by Apple, you will probably need a bit more to make use of it. In addition to that, if you are using an older Mac, then you will still face a few issues while running Sierra. You also have to backup the entire system before installing macOS Sierra, which is a must-do step in any update. For those who have a lot of data on their Macs, this can be a very lengthy procedure.

However, there is a solution to all of that. You can simply go ahead and install the macOS Sierra on an external hard drive, and then boot your Mac from that!

The Prerequisites

There is no doubt about the fact that you will save a lot of trouble and hassle if you install the macOS Sierra on an external drive. It will even let you use the same hard drive with multiple Macs, without updating to Sierra on each of those. However, to begin with this, you will need an external hard drive. Since Apple only requires you to have a little over 8 GB of free space, any hard drive, even one with 128 GB, will do just fine. For better performance, it is recommended that it be an SSD.

Format external hard drive for mac os high sierra
It must be better if you can format the external hard drive beforehand to make it compatible with your Mac.

You will also have to download macOS Sierra from the Mac App Store. To do that, just open the App Store on your Mac, and search for macOS Sierra. You can also download macOS Sierra by directly clicking on the link from your Mac. If your Mac is compatible, then the download option will appear. Click on it, and the download will begin.

The download size is around 5GB, and the total time may vary depending on your internet connection as well as Apple’s servers.

Once you have a hard drive, you can go ahead and follow the simple steps to install and use macOS Sierra from your external drive.

Part 1. Installing macOS Sierra on the external drive

1. Preparing the hard drive for the installation

Before you install macOS Sierra on the hard drive, you will need to clean the external device. Ensure that there is no important data on your hard drive. Then plug it into your Mac, go to Finder and select Applications.

From Applications, go to Utilities and from there, find and double click on Disk Utility. In the Disk Utility tab, select the external hard drive that is connected to the Mac, and then click on Erase at the top.

Now rename it to something like sierra that you will remember, choose 'Mac OS Extended (Journaled)' in the format and then click on Erase. Once the process completes, click on Done, and you are ready to begin installation.

2. Creating the bootable drive

Once your hard drive is formatted, you will need to turn it into a bootable drive. Before you begin this, you will require the Administrator access on your Mac.

Step 1 Go to Finder to open the window, and from the left side, select Applications.

Step 2 From the applications Window, find and click Utilities, and from there, go to Terminal.

Step 3 Now, remember the name that you set for formatting your external drive (i.e. sierra). In case you named it something other than sierra, then make the appropriate changes in the following text. Once you are in the terminal, enter the following text, ensuring to use your drive’s name wherever Volumes/sierra is written.

sudo /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/sierra --applicationpath /Applications/Install macOS Sierra.app –nointeraction

Step 4 When you tap enter, you will be asked the password for the administrator account. As you type the password, no text will be there in the terminal window. Depending on the drive, this process could take a while. Once the window reports ‘Done’, you can close the drive.

Part 2. Using macOS Sierra with the Bootable Hard Drive

Once the above step completes, your external hard drive will be ready to run macOS sierra on any compatible Mac. First, you have to turn off the Mac on which you want to run Sierra from the bootable drive. Then, before switching it on, connect the drive through the Mac’s USB Port.

Then turn on your Mac, and as soon as you hear the startup sound, press the Option key and keep it pressed. Within a few seconds, you will get a screen that asks you to select the appropriate hard drive for booting from. In this screen, select the one on which you have installed macOS Sierra, and you will soon have your Mac running Sierra!

Thus, as you follow these simple steps, you will have configured the macOS Sierra to run from an external hard drive. You do not have to worry about how much free space there is in your Mac, or anything else of the sort. Through this approach, you can run macOS Sierra on any compatible Mac without having to separately download and install it on either one. In addition to that, since there are no backups of the mac’s hard disk required, the process will involve comparatively less hassle.

Any changes or files that you make can be stored on your Mac as well, so you do not have to worry about where your data is. This can be a great way to have the same OS on your personal as well as work Macs. Thus, now, you do not have to bother about freeing up your Mac’s drives or separately downloading it for every PC in the house- just configure it once on an external hard drive, and everything else is taken care of!

Whenever and however you lost your data, keep it in mind that you're able to retrieve data back from Mac by the means of data recovery software like Recoverit. It is the data recovery tool to help you retireve all kinds of data from various devices.
