Disk Utility, a free application included with the Mac operating system, is a multipurpose, easy-to-use tool for working with hard drives, SSDs, and disk images. Among other things, Disk Utility can erase, format, repair, and partition hard drives and SSDs, as well as create RAID arrays.

Open the Disk Management tool. You can do that by typing 'disk format' or 'disk management' in Windows search or going to Control Panel > Administrative Tools > Create and format hard disk partitions.

This guide is for the version of Disk Utility found in OS X 10.10 Yosemite and earlier. Disk Utility underwent some changes in the version included with OS X El Capitan and the new macOS version of the operating system.

Low Level Format for Mac OS X. By: Ellis Davidson. Use Disk Utility to format, partition or do a low-level format of attached hard drives. Low-level formatting is rarely necessary but is useful to ensure that information stored on the hard drive is permanently deleted and irretrievable.

Getting to Know Disk Utility in OS X Yosemite and Earlier

Disk Utility works with disks and volumes. The term 'disk' refers to the drive itself. A volume is a formatted section of a disk. Each disk has a minimum of one volume. You can use Disk Utility to create a single volume or multiple volumes on a disk.

It's important to understand the relationship between a disk and its volumes. You can erase a volume without affecting the rest of the disk, but if you erase the disk, then you erase every volume that it contains.

Disk Utility has three main sections: a toolbar that spans the top of the Disk Utility workspace; a vertical pane on the left that displays disks and volumes; and a work area on the right, where you can perform tasks on a selected disk or volume. Disk Utility is located in Applications > Utilities. Launch it.

If you plan to use Disk Utility for system maintenance purposes as well as for working with hard drives, add it to the Dock. Right-click the Disk Utility icon in the Dock and select Keep in Dock from the pop-up menu.

Erasing a Non-Startup Volume

Erasing a volume is an easy way to free up drive space. Many multimedia applications, such as Adobe Photoshop, need a large amount of contiguous disk space to work. Erasing a volume is a faster way of creating that space than using third-party defragmenting tools. Because this process erases all the data on a volume, many multimedia-savvy individuals create small volumes to hold a project's worth of data and then erase the volume before starting the next project.

The

Select a volume format to use. The Volume Format drop-down menu lists the available drive formats that the Mac supports. Select Mac OS Extended (Journaled).

Click Security Options to open a menu that displays multiple secure erase options.

Optionally, select Zero Out Data. This option is for hard drives only and should not be used with SSDs. Zero Out Data performs a test on the hard drive as it writes zeros to the drive's platters. During the test, Disk Utility maps out any bad sections it finds on the drive's platters so they can't be used. You won't be able to store any important data on a questionable section of the hard drive. The erase process can take a fair amount of time, depending on the drive's capacity.

Make your selection and click OK to closethe Security Options menu.

Click the Erase button. Disk Utility will unmount the volume from the desktop, erase it, and then remount it on the desktop.

Erasing or Formatting a Mac's Startup Drive Using Disk Utility

Disk Utility can't directly erase or format a startup disk, because Disk Utility and all of the system functions it uses are located on that disk. If Disk Utility tried to erase the startup disk, it would at some point erase itself, which could present a problem.

To get around this, use Disk Utility from a source other than the startup disk. One option is your OS X Install DVD if you have one, which includes Disk Utility. Macs without optical drives use the Recovery volume.

Insert the OS X Install DVD in your Mac's CD/DVD reader.
Restart the Mac by selecting the Restart option in the Apple menu. When the display goes blank, press and hold the c key on the keyboard.
Booting from the DVD can take time. After you see the grey screen with the Apple logo in the middle, release the c key.
Select Use English for the main language. when this option appears, and then click the arrow button.
Select Disk Utility from the Utilities menu.
When Disk Utility launches, the drive from the disks and volumes listed at the left side of the Disk Utility window.
Click the Erase tab. The selected drive's name and current format display in the right side of the Disk Utility workspace.
Click Erase. Disk Utility unmounts the drive from the desktop, erases it, and then remounts it on the desktop.

For Macs that do not have an optical drive, you can boot from the Recovery HD to run Disk Utility.

You can then use the steps in the Erase a Non-Startup Volume section.

Quit Disk Utility by selecting Quit Disk Utility from the Disk Utility menu item. This takes you back to the Install OS X window.
Quit the OS X Installer by selecting Quit OS X Installer from the Mac OS X Installer menu item.
Set the startup disk by clicking the Startup Disk button.
Select the disk you want to be the startup disk and then click the Restart button.

Macs format drives with Apple’s HFS+ file system, which Windows won’t recognize or access without third-party software. Macs may also create a protected EFI partition on these drives that you can’t delete with the usual disk-partitioning tools.

Some drives are even sold as “Mac-formatted drives” — this just means they come with the Mac HFS+ file system instead of NTFS or FAT32. Macs can read NTFS drives, and can read and write to FAT32 drives.

Back Up the Drive’s Data First

First, back up the data on the Mac-formatted drive if you have anything important on it. This process won’t actually convert the file system. Instead, we’ll just be wiping the drive and starting over from scratch. Any files on the drive will be erased.

If you have a Mac lying around, you can plug the drive into a Mac and back up the files. If you only have Windows systems available, you can use HFSExplorer to copy files from the drive onto your Windows system drive or another drive. HFSExplorer unfortunately requires you install Java to use it, but it’s the only free option here. You’ll probably want to uninstall Java when you’re done.

First, open the Windows Disk Management tool. Press Windows Key + R to open the Run dialog, type diskmgmt.msc into the box, and press Enter to open it. This tool allows you to manage the partitions on drives connected to your computer — internal ones or external ones connected via USB.

Locate the Mac drive in the list of disks. Be sure you’ve identified the Mac drive — if you accidentally delete partitions from another drive, you could damage your Windows installation or lose your files.

If you’re lucky, you can just right-click each partition on the Mac drive and select Delete Volume to remove the partitions. You can then right-click in the empty space and select New Simple Volume to create a partition and format it with the Windows NTFS or FAT32 file systems.

The Mac drive may have an “EFI System Partition” on it. This partition is marked as protected, so you can’t just right-click and delete it — the delete option will be disabled.

To erase this partition, we’ll have to wipe the entire disk. This process erases everything on the disk, including its files and all its partitions. First, note the number of the disk in the disk management window. For example, in the screenshot below, the Mac-formatted drive is Disk 2.

Next, open a Command Prompt window as administrator. To do this on Windows 8 or Windows 7, press the Windows key once, type cmd , and press Ctrl+Shift+Enter.

Type diskpart into the Command Prompt window and press Enter.

Type list disk at the DISKPART prompt and press Enter to view a list of disks connected to your computer. Identify the number of your Mac disk in the list. It should be the same as the number of the disk in the Disk Management window.

Be sure to double-check this — you could accidentally wipe the wrong drive if you select the wrong disk here.

Type select disk # and press Enter to select the Mac disk, replacing # with the number of the Mac disk. For example, here we’d type select disk 2.

Finally, type clean and press Enter. This command erases the entire selected disk, including all its files and partitions — whether they’re protected or not. You’ll have an empty, uninitialized disk after you do this.

Close the Command Prompt window when you see a message saying “DiskPart succeeded in cleaning the disk.”

Create an NTFS or FAT32 Partition

You can now open the Disk Management window again. If you’ve left it open, you may have to click Action > Rescan Disks to update the data.

Locate the Mac disk in the list. It will be completely empty and display a message saying “Not Initialized.” Right-click it and select Initialize Disk.

Select the MBR or GPT partition table format and click OK to create a partition table for the disk.

Right-click in the unallocated space on the initialized disk and select New Simple Volume. Use the wizard to create a partition with the NTFS or FAT32 file system. The drive will now be formatted for use by Windows systems. There will be no space wasted by protected Mac partitions.

Some Mac functions require an HFS+ formatted drive. For example, Time Machine can only back up to HFS+ formatted drives.
