Erasing your disk: For most reasons to erase, including when reformatting a disk or selling, giving away, or trading in your Mac, you should erase your entire disk.

Use external storage devices with Mac. External hard drives, thumb drives, USB drives, Flash memory cards, and devices like iPod are examples of storage devices that you can connect to your Mac using Thunderbolt, USB, or FireWire cables, or connect wirelessly using Bluetooth. Storage devices (such as external hard drives) can also be available on your network. Step 1: Connect the empty external HD to your Mac and launch Disk Utility. Select the drive from the left sidebar, then click the Partition tab. Under Partition layout, select '2 Partitions.'

Erasing a volume on your disk: In other cases, such as when your disk contains multiple volumes (or partitions) and you don't want to erase them all, you can erase specific volumes on the disk.

Erasing a disk or volume permanently deletes all of its files. Before continuing, make sure that you have a backup of any files that you want to keep.

How to erase your disk

1. Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
   If you're not erasing the disk your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
   
2. Choose View > Show All Devices from the menu bar in Disk Utility. The sidebar now shows your disks (devices) and any containers and volumes within them. The disk your Mac started up from is at the top of the list. In this example, Apple SSD is the startup disk:
   
3. Select the disk that you want to erase. Don't see your disk?
4. Click Erase, then complete these items:
   • Name: Type the name that you want the disk to have after you erase it.
   • Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
   • Scheme: Choose GUID Partition Map.
5. Click Erase to begin erasing your disk and every container and volume within it. You might be asked to enter your Apple ID. Forgot your Apple ID?
6. When done, quit Disk Utility.
7. If you want your Mac to be able to start up from the disk you erased, reinstall macOS on the disk.

How to erase a volume on your disk

1. Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
   If you're not erasing the volume your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
2. In the sidebar of Disk Utility, select the volume that you want to erase. The volume your Mac started up from is named Macintosh HD, unless you changed its name. Don't see your volume?
3. Click Erase, then complete these items:
   • Name: Type the name that you want the volume to have after you erase it.
   • Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
4. If you see an Erase Volume Group button, the volume you selected is part of a volume group. In that case, you should erase the volume group. Otherwise, click Erase to erase just the selected volume. You might be asked to enter your Apple ID. Forgot your Apple ID?
   
5. When done, quit Disk Utility.
6. If you want your Mac to be able to start up from the volume you erased, reinstall macOS on that volume.

Reasons to erase

You can erase at any time, including in circumstances such as these:

• You want to permanently erase all content from your Mac and restore it to factory settings. This is one of the final steps before selling, giving away, or trading in your Mac.
• You're changing the format of a disk, such as from a PC format (FAT, ExFAT, or NTFS) to a Mac format (APFS or Mac OS Extended).
• You received a message that your disk isn't readable by this computer.
• You're trying to resolve a disk issue that Disk Utility can't repair.
• The macOS installer doesn't see your disk or can't install on it. For example, the installer might say that your disk isn't formatted correctly, isn't using a GUID partition scheme, contains a newer version of the operating system, or can't be used to start up your computer.
• The macOS installer says that you may not install to this volume because it is part of an Apple RAID.

About APFS and Mac OS Extended

Disk Utility in macOS High Sierra or later can erase using either the newer APFS (Apple File System) format or the older Mac OS Extended format, and it automatically chooses a compatible format for you.

How to choose between APFS and Mac OS Extended

Disk Utility tries to detect the type of storage and show the appropriate format in the Format menu. If it can't, it chooses Mac OS Extended, which works with all versions of macOS. If you want to change the format, answer these questions:

• Are you formatting the disk that came built into your Mac?
  If the built-in disk came APFS-formatted, Disk Utility suggests APFS. Don't change it to Mac OS Extended.
• Are you about to install macOS High Sierra or later for the first time on the disk?
  If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files.
• Are you preparing a Time Machine backup disk or bootable installer?
  Choose Mac OS Extended (Journaled) for any disk that you plan to use as a Time Machine backup disk or as a bootable installer.
• Will you be using the disk with another Mac?
  If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.

How to identify the format currently in use

If you want to know which format is currently in use, use any of these methods:

• Select the volume in the Disk Utility sidebar, then check the information shown on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
• Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
• Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.

If your disk or volume doesn't appear, or the erase fails

1. Shut down your Mac, then unplug all nonessential devices from your Mac.
2. If you're erasing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
3. If your disk or volume still doesn't appear in Disk Utility, or Disk Utility reports that the erase process failed, your disk or Mac might need service. If you need help, please contact Apple Support.

• If you can't start up from macOS Recovery, you can use a different startup disk instead.
• If Disk Utility shows a Security Options button in the Erase window, you can click that button to choose between a faster (but less secure) erase and a slower (but more secure) erase. Some older versions of Disk Utility offer the option to zero all data instead. These secure-erase options aren't offered or needed for solid-state drives (SSDs) and flash storage.

Summary :

Want to format an external hard drive for Mac and Windows PC? Do you know how to do this work easily? This MiniTool article will show you specific methods to make external hard drive compatible with Mac and PC, which are easy and safe to complete.

As we know, external hard drives are widely used to backup data or interchange files among different computers. Well, is there an external hard drive that could be shared between Mac and Windows PC? Of course, there is. Actually, most external hard disks could be compatible with Mac and PC as long as you format them correctly.

Why Need to Format External Hard Drive for Mac and PC

To put it simply, if you want to share external hard drive between Mac and PC, you need to format an external hard drive for Mac and PC.

Currently, hard drives for Windows PC are always formatted with NTFS, while hard disks for Mac are formatted with HFS+. However, when we connect a NTFS formatted disk to Mac, Mac OS X doesn't allow us to write files to the drive neither edit files, though it can read a NTFS drive. Similarly, Windows OS will ask us to format the HFS+ formatted drive when we connecting such a disk, let along edit files saved on HFS+ formatted hard disks unless we resort to third party programs.

But luckily, there are file systems well supported by both Mac and Windows PC, and they are FAT32 (it might be called MS-DOS on Mac) and exFAT. As long as we format the external hard drive to one of these 2 file systems, it can be shared between Mac and Windows.

Further Reading

Both FAT32 and exFAT have advantages and disadvantages.

FAT32: FAT32 works with all versions of Windows, Mac OS, Linux, game consoles, etc.

However, single files on a FAT32 drive can't be larger than 4GB. If your external drive saves files larger than 4GB or you plan to save larger files to this drive, converting to FAT32 is not recommended.

In addition, a FAT32 partition must be not more than 32GB if you create it in Windows Disk Management. Of course, there is free partition manager that can help create a FAT32 volume up to 2TB, which also functions correctly.

exFAT: exFAT has very large file size and partition size limits, which means it's a good idea to format your external hard drive to exFAT.

Nevertheless, a lot of users complained that exFAT is slow, and they highly suggest using FAT32 if you can avoid file size constraints.

Three Options for Accessing NTFS Drives on Mac

Paid Third-Party Drivers

Some paid third-party NTFS drivers for Mac can be used to access NTFS drives on Mac. They work well and they have better performance than the free solutions which will be mentioned in the following part. Paragon NTFS for Mac is such a driver.

Besides, you can also use the paid third-party file system converters to convert NTFS to FAT32 or exFAT which are compatible with both Mac and PC. MiniTool Partition Wizard is one representative.

Free Third-Party Drivers

FUSE for macOS is a free and open-source NTFS driver that can enable write support. But, this solution is slower relatively. And the automatically mounting NTFS partitions in read-write mode can be a security risk for your Mac computer.

Apple’s Experimental NTFS-Write Support

The Mac OS has an experimental support for writing to NTFS drives. Usually, it is disabled by default and needs some messing around in the Mac terminal to enable it.

It doesn’t work properly all the time and could lead to potential issues with your NTFS file system. For example, it had corrupted data before. Thus, we don’t suggest using this tool and we believe it is disabled by this reason.

Here, we recommend using the paid third-party tools since they are easy-to-use and can do good work for you.

Then, we will introduce these three options for you in the following content.

The Best Paid Third-Party Driver: Paragon NTFS for Mac

Paragon NTFS for Mac can write, edit, delete, copy, or move files on NTFS volumes from your Mac computer. It offers a 10-day free trial. If you want to use it all the time, you need to pay for it.

With it, you don’t have to fiddle with terminal commands to mount partitions manually. Additionally, it can mount partitions automatically and safely. More importantly, it can code with the potential corruption. If you purchase a Seagate drive, you can even get a free download of Paragon NTFS for Mac.

All in all, it does its works well and gives you good user’s experience.

The Best Free Third-Party Drivers: FUSE for macOS

FUSE for macOS is a free solution to access NTFS on Mac. But it is less secure.

If you want to make automatically mount NTFS partitions in read-write mode on Mac, you need to temporarily disable the System Integrity Protection and replace one of Apple’s built-in tools with a binary that is more vulnerable to attack. Thus, your Mac is in danger when using this driver.

However, you can use it to manually mount NTFS partitions in read-write mode if you never mind using the Terminal. This will be safer, but you need to do more work. You can go to google the steps and see how complex they are.

Apple’s Experimental NTFS-Writing Support: Don’t Do This, Seriously

Although we mentioned this method in our article, we still don’t recommend it because it is the least tested. It is just for educational purposes, and it is available on Mac OS 10.12 Sierra. Perhaps, it will be unstable forever.
