Warming: Formating a drive, also erase its data. Although you can still get it back, but it’s much harder after formatting. So if you can’t afford losing you data, take backup.

Which Format to choose?

Choosing a right file system is a bit tricky, so here are some pros and cons of all file system.

NTFS: This is windows propriety file system. Most external drives come preformatted in NTFS so that they can be used easily with Windows. However, NTFS drives are read only in MAC, but you can get write access by using software like NTFS-3g. It also works in Linux. And to support NTFS on Android use Stick mount or Paragon NTFS, HFS and exFAT.

HFS+: This MAC propriety file system and is used in iOS and MAC. If you format your external hard drive to HFS, you can use it on MAC and Linux (by removing journaling). However, to use it on Windows you can HFS explorer (read only).

ext4: This is a default file system for linux OS (including Raspberry Pi). To read an ext4 drive on Windows, you can Ext2Read and OSXfuse for MAC. However, I have not really use this format much, so we just skip it.

FAT32: This oldest file system and work with all OS i.e. Windows, MAC, Linux, Android, even TV, and PS3 etc. This is why it’s used in all small flash drive. Although it lacks all modern features and comes with 4 GB limit for single file size.

exFAT: is the extended version of exFAT. It works fine with Windows and MAC (all the modern version). For Android, you can use Stick mount app (root needed). However being a windows propriety file system, it does not play well in open source environment. But unlike FAT32, it does not have 4GB limit for single file size. Thus making it ideal for SDcards of the high-end camera.

How to Format an External Hard drive or Pen drive

Now that we know the good and bad about every file system, let see how to format a drive in Windows, MAC, and Linux.

Windows

Formatting a drive on Windows is quite simple. Plug in your external HDD to the USB port of your computer> then go to my computer > find your external drive > right-click it > and select format.

A new window will open, select the desired file system, keep the allocation unit size to default and check mark quick format (or it will take more time). Once done hit the format button and that’s it. Within seconds, you will have your drive in the new format.

Note: While formatting a pen drive you will see FAT32, exFAT, and NTFS as the available file system. However for external HDD you won’t see the FAT32 (windows don’t suggest fat32 for bigger drives) However to get other format option you can use third-party software.

MAC

Open your terminal and type in the following command to install GParterd.

sudo apt-get install gparted

Once installed, type the following command to launch the program.

sudo gparted

Want to use NTFS drives on a Mac? In this guide we show you how to use those Windows-formatted drives in macOS.

The Mac versus PC debate isn’t going to be settled anytime soon but there’s no denying that Windows computers are more widespread. For this reason, many manufacturers of external hard drives and USB sticks pre-format their devices to NTFS.

This format was created for Microsoft and allows users to quickly plug their drives into Windows machines and work with files. As NTFS is proprietary, Apple would need a special license to use it fully on the Macs they sell.

Instead of doing this, macOS has been designed to read NTFS-formatted drives but not write to them. In other words, as a Mac user you can only open and view files on Windows drives: you can’t change them in anyway, nor can you copy new files to NTFS format disks.

In this guide, you’ll discover several solutions to this dilemma from formatting drives to a more universal file system to using third-party tools.

1. Format to FAT32

If you have an NTFS drive you can use macOS’ Disk Utility to reformat it to FAT32. This is simple to do and means the data on your drive/USB stick can be read and written on both Macs and PCs.

Be aware that the FAT32 format isn’t as efficient as NTFS: it only supports files sizes of up to 4GB. This may pose a problem if you’re using the drive to store high-quality videos. More information on FAT32 versus NTFS is available from Microsoft Support.

To get started, click the Spotlight icon at the top right of your screen and enter ‘Disk’ to launch Disk Utility. Insert your NTFS drive or USB stick and click to highlight the disk name in the white box on the left-hand side of the window.

Select the ‘Erase’ tab. Under ‘Format’ choose ‘(MS-DOS FAT)’. Enter a new name for the drive in the field above if you wish.

Click ‘Erase’ to continue. Read the warning carefully before proceeding, as this process will delete any existing data on the drive. From now on you’ll be able to move files to your drive and edit them in place from a Mac or PC.

2. Use a third-party app

The fact that macOS doesn’t support Windows NTFS drives out of the box has led to the development of a number of third-party apps, which are licensed to both read and write to Windows disks.

These can be particularly helpful if you regularly have to plug your drive into both a Mac and PC both use file sizes larger than that supported by the more universal FAT32 format.

One of the strongest contenders for macOS is Microsoft NTFS for Mac by Paragon, which offers a ten-day free trial of its features. Once installed, the app will mount your Windows drives allowing you to change or remove files to your hearts content.

At the time of writing there doesn’t seem to be any freeware macOS programs offering NTFS write support, which may put off users on a budget.

3. Enable NTFS write support in Terminal

If reformatting your NTFS drive for Mac is not an option, you can enable write support for specific Windows disks using macOS Terminal. This is an experimental feature and could lead to data loss, so make sure to do a full backup of both your Mac and any data on the drive before continuing.

The main benefit of using Terminal in this way is that it’s quick to do and no third-party software is required. As this feature is still in the testing phase however, your files could become corrupted at anytime, so proceed with caution.

To get started, click the Spotlight icon at the top right of your screen and enter ‘Terminal’. Connect your NTFS drive, then enter the command:

This will open the list of drives recognised by macOS. Use the arrow keys on your keyboard to scroll to the very end and add the following line, replacing ‘NAME’ with the actual name of your NTFS drive e.g. USB1 (if you’re unsure what this is, simply open Disk Utility):

Press Ctrl+O to save the list, and then press Ctrl+X to exit NANO. Next, connect your Windows drive to the Mac.

Open Finder, then click Go’> Go to Folder, then type ‘/Volumes/NAME’ where ‘NAME’ is the name of your NTFS drive.

Click ‘Go’ to access your Windows disk. You should now be able to edit existing files and copy new ones here.

4. Use BootCamp

Bootcamp is macOS’ own built-in utility for installing Microsoft Windows on your Mac. The most recent version of macOS (Mojave) supports Windows 10. During the setup process, users shrink the size of their existing macOS installation to make room for Windows.

This allows you to boot both operating systems on your Mac. Once set up, Windows 10 will function on your Mac in just the same way as it would on a regular PC. This includes working with NTFS-formatted drives.

Mac Formats For Hard Drives And Downloads

To get started, all you need is an internet connection, a valid Windows 10 DVD and a USB stick of at least 8GB. See our guide on setting up BootCamp for more details on how to get started.

Although BootCamp is easy to set up and use, you must purchase a Windows 10 license to keep using the OS after 90 days. You’ll also naturally will have to work with files using Microsoft apps instead of those designed for Mac like iMovie.

If you enjoy using the iWorks app however (Pages, Keynotes & Numbers), you can work with the online versions of these tools on a PC by accessing iCloud via your browser.

When using BootCamp remember that any files you save to the Windows 10 section of the hard disk itself can’t be accessed when you reboot into macOS and vice versa.

5. Move to the Cloud

If you only want to work or collaborate on a few files, why not ditch the drives altogether and place your files in the Cloud?

Online services such as iCloud Drive offer a generous free allowance (5GB) and allow you to immediately sync, edit and share files even if they were originally created for Windows and saved to an NTFS disk.

To take advantage of iCloud, simply open your Windows drive in Finder then copy and paste any files you want to work with to the location ‘iCloud Drive’. If you don’t see this is the side pane, open System Preferences > iCloud to check you’re signed in and that this service is enabled.
