Create a disk image using Disk Utility on Mac

You can use Disk Utility to create a disk image, which is a file that contains other files and folders.

Note: You can burn information to a CD or DVD using the Burn command in the Finder. See Burn CDs and DVDs.

Create a blank disk image for storage

You can create an empty disk image, add data to it, then use it to create disks, CDs, or DVDs.

In the Disk Utility app on your Mac, choose File > New Image > Blank Image.

Enter a filename for the disk image, add tags if necessary, then choose where to save it.

This is the name that appears in the Finder, where you save the disk image file before opening it.

In the Name field, enter the name for the disk image.

This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.

In the Size field, enter a size for the disk image.

Click the Format pop-up menu, then choose the format for the disk:

If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive).

If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).

If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT.

To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

Click the Partitions pop-up menu, then choose a partition layout.

Click the Image Format pop-up menu, then choose an option:

Sparse bundle disk image: Same as a sparse disk image (below), but the directory data for the image is stored differently. Uses the .sparsebundle file extension.

Sparse disk image: Creates an expandable file that shrinks and grows as needed. No additional space is used. Uses the .sparseimage file extension.

Read/write disk image: Allows you to add files to the disk image after it’s created. Uses the .dmg file extension.

DVD/CD master: Changes the size of the image to 177 MB (CD 8 cm). Uses the .cdr file extension.

Click Save, then click Done.

Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

In the Finder, copy your files to the mounted disk image, then eject it.

For more information about disk image types, see the manual (man) page for hdiutil.

Create a disk image from a disk or connected device

You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.

In the Disk Utility app on your Mac, select a disk, volume, or connected device in the sidebar.

Choose File > New Image, then choose “Image from [device name].”

Enter a filename for the disk image, add tags if necessary, then choose where to save it.

This is the name that appears in the Finder, where you save the disk image file before opening it.

Click the Format pop-up menu, then choose an option:

Read-only: The disk image can’t be written to, and is quicker to create and open.

Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.

Read/write: Allows you to add files to the disk image after it’s created.

DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.

To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

Click Save, then click Done.

Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

Important: Don’t create a disk image of a disk that you believe to be failing or that contains corrupted information. The disk image may not serve as a reliable backup.

For technical information about creating a restore disk image, see the Apple Software Restore (ASR) manual (man) page.

Create a disk image from a folder or connected device

You can create a disk image that contains the contents of a folder or connected device, such as a USB device. This method doesn’t copy a device’s free space to the disk image. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 10 GB in size and include only data, not free space. You can then restore that disk image to another volume.

In the Disk Utility app on your Mac, choose File > New Image, then choose Image from Folder.

Select the folder or connected device in the dialog that appears, then click Open.

Enter a filename for the disk image, add tags if necessary, then choose where to save it.

This is the name that appears in the Finder, where you save the disk image file before opening it.

To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.

Click the Image Format pop-up menu, then choose an option:

Read-only: The disk image can’t be written to, and is quicker to create and open.

Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.

Read/write: Allows you to add files to the disk image after it’s created.

DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.

Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF.

Click Save, then click Done.

Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

For technical information about creating a restore disk image, see the Apple Software Restore (ASR) manual (man) page.

Create a secure disk image

If you have confidential documents that you don’t want others to see without your permission, you can put them in an encrypted disk image.

Note: If you want to protect the contents of the system disk, turn on FileVault using the FileVault pane of Security & Privacy Preferences.

In the Disk Utility app on your Mac, choose File > New Image > Blank Image.

Enter a filename for the disk image, add tags if necessary, then choose where to save it.

This is the name that appears in the Finder, where you save the disk image file before opening it.

In the Name field, enter the name for the disk image.

This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.

In the Size field, enter a size for the disk image.

Click the Format pop-up menu, then choose a format:

If you’re using the encrypted disk image with a Mac computer using macOS 10.13 or later, choose APFS or APFS (Case-sensitive).

If you’re using the encrypted disk image with a Mac computer using macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).

Click the Encryption pop-up menu, then choose an encryption option.

Enter and re-enter a password to unlock the disk image, then click Choose.

WARNING: If you forget this password, you won’t be able to open the disk image and view any of the files.

Use the default settings for the rest of the options:

Click the Partitions pop-up menu, then choose Single partition — GUID Partition Map.

Click the Image Format pop-up menu, then choose “read/write” disk image.

Click Save, then click Done.

Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.

In the Finder , copy the documents you want to protect to the disk image.

If you want to erase the original documents so they can’t be recovered, drag them to the Trash, then choose Finder > Empty Trash.

When you’re finished using the documents on the secure disk image, be sure to eject the disk image. As long as it’s available on your desktop, anyone with access to your computer can use the documents on it.

To access the data in a disk image, double-click it. It appears on your desktop, and you can add, remove, and edit files on it just as you would with a disk.

Question: Q: Where is the Disk Image Mounter Application located?

Sometimes when I download something I get it as a MPEG when it should be a DMG. I know I can go to Get Info and select open with but Disk Image Mounter does not show up so where would I find it exaclty? I tried doing a search and nothing came up either.

iMac Intel Core 2 Duo 17″ & 1.67GHz PowerPC G4 512 MB DDR SDRAM, Mac OS X (10.4.9), itunes 7.1.1

It’s a sneaky one. I tried to catch it in the ActivityMonitor process list — but it pops into existence for only a second or two when an image is first mounted. Too quick to inspect. But unix always provides a solution (or three). Try this in Terminal.app:

sudo find / -name «\ DiskImageMounter«

/System/Library/CoreServices/DiskImageMounter.app
/System/Library/CoreServices/DiskImageMounter.app/Contents/MacOS/DiskImageMounte r
/System/Library/CoreServices/DiskImageMounter.app/Contents/Resources/DiskImageMo unter.scriptSuite
/System/Library/CoreServices/DiskImageMounter.app/Contents/Resources/DiskImageMo unter.scriptTerminology

BTW, the «sudo» prefix is optional — it just avoids cluttering-up the output with a gaggle of «permission denied» error messages. If you don’t have admin privileges, redirecting stderr to the bit bucket will do the same:

find / -name «\ DiskImageMounter» 2> /dev/null

. in the beginning was the command line,

Not sure how a .dmg would end up with an .mpg suffix — but if the file contents really are in .dmg format, simply re-naming the file to a .dmg suffix should do the trick. (If it’s anything valuable/irreplaceable, I’d suggest making copy before running that experiment.)

An MPEG isn’t a «disk image» (in the unix filesystem sense), so D.I.M. wouldn’t know what to do with it.

I tried just clicking DiskImageMounter.app, but only got a «puff of mist» and no window — pretty much what I expected. It’s clearly not intended to be run as a stand-alone app, and probably requires some magical incantations/parameters at launch-time.

If you’re a command-line hacker, you might find something interesting in the man pages for: hdiutil(1), hdid(8), load_hdi(8), and stuff like that.

Как просто монтировать образы дисков в Windows, Linux и Mac?

Использование ISO-образов дисков набирает все большую популярность, т.к. современные компьютеры все чаще вообще не оборудуются оптическими приводами. Мы уже ранее писали о том, как создать образ диска в Windows, Ubuntu Linux и Mac OS X. Теперь давайте разберемся, как монтировать образы дисков в Windows, Linux и Mac OS X.

Образы диска можно использовать и имея оптический дисковод: для записи копии диска в будущем, создания резервных копий. Образ диска — 100% копия физического диска в одном файле.

Монтирование ISO-образа в Windows

Windows 10 позволяет монтировать образы формата .ISO и .IMG штатными средствами, без установки стороннего ПО. Просто осуществите двойной клик по .ISO или .IMG файлу образа и система монтирует его. Если так не получится — выделите образ диска и в ленте Выберите кнопку Монтировать.

Для монтирования образа диска в Windows 7 и версиях старше, а так же для монтирования образов в других форматах, таких как BIN/CUE, NRG, MDS/MDF или CCD — мы рекомендуем легкую, бесплатную программу с открытым исходным кодом — WinCDEmu.

После установки программы для монтирования диска достаточно будет лишь кликнуть по файлу образа правой кнопкой и выбрать «Указать устройство и монтировать», так же можно монтировать образы дисков не поддерживаемых Windows форматов.

Некоторые другие программы для монтирования образов так же имеют поддержку эмуляции образов дисков защищенных от копирования разными технологиями. Но, как вы можете догадаться, такой функционал никогда не появится ни в одной версии Windows штатно ?

Монтирование ISO-образа в Mac OS X

В Mac двойной клик по большинству файлов образов сразу монтирует его и открывает доступ к его содержимому.

Приложение DiskImageMounter позволяет монтировать .ISO, .IMG, .CDR и другие образу дисков. Если программа установлена — диски будут монтироваться по двойному клику, если же нет — правый клик > открыть с помощью > DiskImageMounter

Вы так же можете попробовать образ диска с помощью стандартной дисковой утилиты. Нажмите Command+Пробел, введите Disk Utility и нажмите Enter для открытия. В меню файл выберите Открыть образ диска и выберите свой образ для монтирования.

Монтирование ISO-образа в Ubuntu Linux

Дистрибутив Ubuntu включает в себя приложение «Archive Mounter«, которое позволяет монтировать ISO файлы и подобные файлы образов с помощью графического интерфейса. Для его использования кликните правой клавишей мышки по ISO файлу или другому образу диска и перейдите в Открыть с помощью > «Disk Image Mounter».

Извлечь устройство позже можно кликнув по иконке Извлечь в сайдбаре.

Так как в Linux многие действия принято выполнять с помощью терминала, то для этого откройте окно терминала и создайте папку /mnt/image, в которую потом монтируется ISO образ.

Монтируется ISO в Linux командой

где, /home/NAME/Downloads/image.iso — путь к вашему файлу образа диска.

Для размонтирования ISO в Linux используйте команду:

Все. Вот так просто монтировать образы дисков в различных системах.
