I have attached an HFS+ hard drive with Mac OS X installed to an Ubuntu machine because while booting the Mac shows a blinking folder with a question mark. I searched Google and the results say that the 3 TB HDD is damaged. When I attach the HDD it reads well in Ubuntu.

Most accessory makers tend to build accessories for the more dominant platforms, which is why a lot of computer peripherals tend to be more focused towards Windows users. This can make it a bit tricky if you’re a Mac user, especially if you’re looking to buy an external hard drive where sometimes, some models might come preformatted for Windows use.

We’re sure that some of you have encountered situations where you plug in an external hard drive or USB flash drive to your Mac computer, only to find that it won’t read or you can make changes to it due to it being formatted only for Windows. However, if you’re looking to ensure full compatibility between Windows and Mac, check out the steps below.

How To Format An External Hard Drive For Mac

The process to format an external hard drive or USB flash drive for your Mac is pretty easy and straightforward.

1. Plug in your external hard drive or USB flash drive to your Mac computer
2. Launch the Disk Utility app which can be found in Applications > Other
3. Select the drive from the left side of the window
   
4. Click the Erase tab at the top of the screen
   
5. Under Format, select ExFAT
   
6. Click Erase and depending on how much you have stored on it, it could take seconds or minutes to complete.
7. Once completed, you should see the new file type of your hard drive (note that prior to formatting it said NTFS).
   

Which File Format Should I Use?

During the process of formatting your hard drive, under the Format section you would have noticed that there are quite a few different options for you to choose from, so the question is, what are the differences between the file formats and which should you choose?

ExFAT

This is the option that we told you that you should choose if you wish to ensure that your hard drive will be compatible (which means that it can read and write) on both Windows and Mac computer systems.

MS-DOS FAT

Also known as FAT32 on some systems, this is another option that you can choose if you want to format a hard drive that will be compatible across Windows and Mac. However, one of the main differences between FAT32 and ExFat is that the former will only support file sizes of up to 4GB. This means that if you’re looking to transfer a video file that’s over 4GB in size, you will not be able to. This is due to the fact that FAT32 is an older file system.

APFS (Apple File System)

This is a newer file system that Apple introduced with its High Sierra update. It will be the default format that will be used for internal drives and also newer external hard drives that are designed specifically for Mac use. The upside is that it is more efficient, more reliable, and users can also choose to have it encrypted to protect the contents of their computer.

The downside is that it will not be compatible with older versions of macOS and will also not be compatible with Windows or Linux machines. However, if you’re only using Mac computers then this could be an option to consider.

Mac OS Extended (Journaled)

This file format was also previously known as HFS+. It was the file system that Apple had used prior to introducing APFS. For older Mac computers that do not run High Sierra or newer, Mac OS Extended will be the default format of choice. Similar to APFS, there are options to have it encrypted and password protected, and also users can choose to format it so that it can be case-sensitive for files that might require them.

Also, just like APFS, Mac OS Extended is not readable on Windows machines, so if you’re looking for cross-platform compatibility, ExFAT is still the best choice for now.

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.

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.

• If you can't start up from macOS Recovery, you can use a different startup disk instead.
