In all likelihood, you’re more acquainted with formatting an external hard drive than your Mac’s internal one, aren’t you?

This means you can’t store files and neither can you copy or delete anything from the drive. At times, formatting your drive could be the only logical solution to fixing it; other times, simple fixes could get it working again.

Part 1: How to Format Hard Disk on Mac

The simple reason you might want to completely wipe your Mac’s internal drive is that it has encountered one serious error or another. Apple has given you several options to choose from should you ever need to format or reformat your drive. No one needs to tell you formatting your Mac’s drive entails reinstalling the macOS afterward, right? As long as you’re aware of that, you’re good to go.

1. How to Format New Hard Disk

Formatting a new disk, in the simplest of terms, means setting up a file system in the new drive to work with your macOS. There are different file systems, as you’ll soon find out, and each has unique features that some of the other file systems may or may not have.

a) Start up your Mac and press the “Option” + “⌘” + “R” keys to boot into 'Recovery'. Let go of the keys once the Apple logo or spinning globe comes on. The “Utilities” window will then show up.

b) Click on “Erase” to format the new hard disk. If you’re prompted, choose “macOS Extended (Journaled)” or any of the other file systems based on your needs or preference. This is also where you give the drive a name.

c) Go back to “Disk Utility” and select “Install macOS”. Restart your Mac once it’s done. The end.

2. How to Reformat Hard Drive

You can think of reformatting your drive as a way to reset it by putting a new file system into the drive to supplant the old one. It can also mean putting the same file system in the drive to fix it if it’s faulty. Reformatting your drive will get rid of your files, of course, but it also gets rid of any errors.

a) Yes, you’re going to be using “Disk Utility” again. Matter of fact, you’ll be seeing this tool a lot throughout the article. Now, fire it up!

b) Look to the left of the “Disk Utilities” window and select the drive to be reformatted. Click on the “Erase” button.

c) Follow prompts to select a file system. Choose “Mac OS Extended (Journaled)” or another file system if you’re aware of what each of them offers. Click “Erase” and let the disk be formatted. Restart your Mac and you’re done here.

4. Tips for Formatting HDD on Mac

• Disk Utility is the first tool you should utilize when it comes to formatting any HHD on your Mac. Even if the hard drive is corrupted and can’t be formatted, you can use Disk Utility to fix and then format it; if the error isn’t too grave, formatting alone should suffice.
• The importance of backing up your files BEFORE formatting cannot be emphasized enough. Backing them up might be a tedious task, particularly if your hard drive is the motherload of data, but would you rather forgo it and jeopardize the security of your files? Because you’re not a machine and it’s probable for you to forget you still have important files in the drive to be formatted. Don’t be too hasty.
• If you’re not near a power source, make sure your battery is fully charged before you start the formatting the process. Your Mac suddenly turning off while your drive is being repaired or formatted will only bring forth new errors. Be wary of that.

Part 2: When You Need to Format Disk on Mac

There’s nothing complex about what formatting HDD is used for. It completely erases the contents of your Mac’s drive. That’s simple enough for anyone to understand, but the ramifications of formatting a drive are very broad. A single click of a button can mean the erasure of decades’ and terabytes’ worth of files. That brings up the question of when it becomes necessary for you to format the drive in your Mac.

• You and your Mac have had a good run but it’s final time to say goodbye, so you give it out to a buddy. As close as the two of you may be, you still wouldn’t want him having to access your files, would you?
• Mac systems fetch an impressive price, so selling it is an easy way to make a quick buck. Just remember you have sensitive data in your drive. For your Mac’s new owner, the files you left in it could just be a bonus of sorts, but for you, it’s an inadvertent breach of your privacy.
• Serious errors or virus can doctor your macOS so it ignores your commands and wreaks havoc on your drive and files. It’s often a good idea to format the drive clean so both virus and errors are wiped off into oblivion.
• Restoring your Mac to factory settings entails formatting the disk too.
• If you intend to change the format of the disk, perhaps from exFAT to APFS, then erasing your disk is necessary.
• If an annoying message keeps notifying you that your disk can’t be read by your Mac, it’s time to format it.

Part 3: Different Formats of Mac Hard Drive

The file formats out there waiting to be used by you are few. Knowing the right one to choose depends on what you intend the drive to be primarily used for. Keyboard remapper for mac os sierra. Have a read below and determine which one best suits your needs.

APFS (Apple File System)

This is the newest file system Apple incorporated into their Mac systems, so naturally, you can expect it to be more advanced, reliable and efficient than prior versions. APFS only works on Sierra and if your Mac’s drive isn’t SSD, APFS won’t work for you too.

Mac OS Extended (Journaled)

This was Apple’s default file system for their Mac systems before APFS entered the picture. There’s another variant, Mac OS Extended (Journaled, Encrypted), which sees greater use by people who encrypt their drives and make passwords a necessity. Mac OS Extended (Case-sensitive, Journaled) is another variant that is case-sensitive to names of folders; folders named “CAR” and “Car” are not the same. The 4th type is Mac OS Extended (Case-sensitive, Journaled, Encrypted). It has all the distinctive features of its three brethren listed up there rolled into one.

NTFS

This is Windows’ very own default file system but it can still be read by your Mac; writing to it it’s a different story, though.

exFAT

exFAT is one of the more versatile file systems because it’s compatible with both macOS and Windows. Either operating system can read drives formatted with exFAT, and it’s capable of storing a file larger than 4GB.

MS-DOS FAT (FAT32)

This file system is also readable by Mac, Windows and Linux, so if you often share external hard drives between the 3 operating system, you might want to go with this option. It’s one flaw is you can’t copy files larger than 4GB in size each.

Okay, those are the file systems, but how do you know which one of them your Mac is using?

1. Open up “Disk Utility” and select the volume or drive. Open up “System Configuration” and choose “Storage”.
2. Choose the volume in “Finder”, then select “File” and “Get info” from the menu bar. The next window will show you the Format of the disk.

Part 4: How to Fix Errors When Formatting Mac Hard Drive

Formatting your drive should be an affair that takes up, at most, minutes of your time. But of course, this isn’t always the case, is it? Sometimes, your Mac just decides to make things a little harder for you. Don’t sweat it. A few solutions have been rounded up and written out for you down below.

Problem 1. Unable to Format Hard Drive

Does your Mac show you errors similar to what’s in the image below? Chances are you don’t even know what causes them. Thankfully, fixing them is a breeze.

1. Open up “Utilities”, then your “Applications” folder. Find “Disk Utility” from the list and launch it.

2. Click on “View” and choose “Show All Devices” in the dropdown menu. Next, you choose the “Top Volume” of the drive to be formatted.

3. Click on “Erase”, then give a name to the drive. When it comes to “Format”, you can either choose APFS or Mac OS Extended.

4. Choose a “Scheme” (go with “GUID Partition Map”). Click on “Erase” and wait until you see the green checkmark. That means it’s done.

Problem 2. Erase All Disk Data Without Backup

By now, everyone who handles large amounts of data should be diligent in making regular backups of their files, right? Nope, because there’s always that one guy who only decides to do this when it’s too late. Have you ever been in such a situation?

If you have, why not prepare yourself for a similar eventuality? Download and install Recoverit Mac Data Recovery to safeguard your files against accidental deletion and crashed drive; or if you simply forget to backup your data prior to formatting your drive. The steps below will show you how to do this.

Step 1. Choose a Location

Launch Recoverit and select the hard disk to be scanned (the one that was formatted). It will be among the other drives displayed on the first window you see once the software opens up. Click “Start.”

Step 2. Scan the Location

Use “File Type” and “File Path” to narrow your search and make it easier to recover particular files-as against everything you lost. The scan will end after a given time and show you a preview of your lost files.

Step 3. Preview & Recover Formatted Data

You will see check boxes to the left of the Recoverit window. Those are the files you came looking for. Select particular ones or all of them. Click the “Recover” ribbon and the files will be recovered. And don’t forget to save everything you’ve recovered onto a new drive.

Don’t bother yourself with the format of your Mac’s disk or how much data you lost. Recoverit’s tools and features mean it’s perfectly capable of recovering data which was erased hours, weeks, months or even years ago. Surprised? Yeah, it has that much power. Just download, install and run it. It doesn’t get any easier than that, does it?

Problem 3: Hard Drive Not Showing up

When your drive is not mounting on Mac, here are two solutions to help you.

1. Boot Mac into Recovery Mode

• To fix it, boot your Mac into “Recovery Mode” (already explained earlier).
• Choose “Disk Utility” from the “Utilities” menu, then choose the faulty drive and click on “First Aid”. Click “Run” to verify and repair any errors.

2. Change Finder Settings

• It’s possible your drive won’t show up in Finder because your Mac is yet to be set up to display hard drives. Fix it by opening up “Finder” and going to “Preferences.”
• Click on the “General” tab and choose “Hard disks.” The drive will be visible now.

Closing Words
