Here are instructions on how to use Disk Utility to securely erase a hard drive connected internally or externally to your Mac. These instructions were written for Mac OS X 10.4 to 10.6. The process is very similar on older versions of Mac OS X, but the screens will look a bit different.
[UpdateNov2014: If your Mac has OS X 10.7 or newer installed then Apple didn’t give you an OS X install disc with your Mac. Instead, you can startup your Mac from its Recovery Partition and then use its copy of Disk Utility to securely erase your hard. Click one of the links below to follow the appropriate instructions for the type of hard drive that you have. If you’re not sure which type of hard drive you have, then you most likely have a mechanical, spinning, hard drive.

Sep 06, 2019 The simplest way to install macOS or OS X on a new hard drive is by using Internet Recovery Mode. This mode is only available on Apple computers made after 2009 that were running OS X Lion or later. If your Mac is from before 2009 or never had OS X. Back in the days before Mac OS X Lion launched in 2011 there wasn't a Recovery partition, instead you needed to have a physical disc with the software on it and an optical drive to insert it into.
If your Mac has a solid state drive (SSD), aka Flash Storage, and OS X 10.7 or newer then use these instructions.]
Requirements
You’ll need either the Mac OS X install disk that came with your Mac or another OS X install disk that’ll boot your Mac, such as a retail copy of the Mac OS X 10.5 or 10.6 install disk.
I recommend securely erasing a hard drive before you recycle it or give it away. The instructions below include the option to re-install Mac OS X onto the hard drive at the end of the process.
If you’re securely erasing an external hard drive you do not need to use a Mac OS X install disk. Instead, you can simply open Disk Utility which you’ll find in the Utilities folder inside the Applications folder. In Disk Utility, select the external hard drive and then follow the last few steps of these instructions to erase it using one of the Security Options described below.
Background
Technically, it’s not possible to erase or remove data from hard drives. Thus “securely erasing” is a misnomer. Instead, what we’ll be doing is over-writing the data on your hard drive with gibberish, a random string of bits of data. When you securely erase your hard drive you’ll have a choice of how much over-writing you want to do. This process can take many hours if you select the 7-pass overwrite procedure. I recommend starting this process and then letting it run overnight.
- Insert the Mac OS X install disc that came with your Mac.
- Note: The disc will begin the process of installing Mac OS X on your Mac. Whether or not you actually choose to install Mac OS X is your choice, but if you do, you’ll do it after you’ve securely erased your Mac’s hard drive.
- Select your preferred language from the list presented.
- When you see the welcome screen for the Mac OS X Installer, go to the menu named Utilities and select Disk Utility.
- In the left pane of the Disk Utility window, click on the hard drive you want to erase.
- In the right pane of the Disk Utility window, click the Erase tab.
- Click the Security Options button.
- I recommend that you select the 7-Pass Erase options, but you could choose the 35-Pass Erase option. Here’s my description of these options.
Don’t Erase Data— This option does not provide any security. This option only over-writes the directories on the hard drive. Your files could still be recovered.
Zero Out Data— Provides a pretty good level of security. All of your files are over-written with a string of zeroes. There are forensics utilities that in theory could retrieve some data.
7-Pass Erase— Provides a lot of security. This is considered sufficient by government standards to erase data from a disk. It writes a random string of ones and zeroes over your data files seven times. It may take several hours or more to complete this process.
35-Pass Erase— Provides the maximum amount of security offered. This option takes an extremely long time, possibly more than one day.

- Click the radio button in front of 7-Pass Erase.
- Click OK.
- Click the Erase button next to the Security Options button.
- Confirm you want to erase and the process will be begin.
- If you want to install Mac OS X then go to the Disk Utility menu and select Quit after the erase is complete.
- You’ll be taken back to the Mac OS X Installer welcome window. Click Continue.
- Agree to the software license.
- In the “Select a Destination” window click on the icon for the hard drive which you just erased and then click Continue.
- Click the Install button to start the installation process. Depending upon the speed of your Mac and the version of Mac OS X which you are installing this process could commonly take anywhere from 20-60 minutes.
Update Oct 2014: In OS X 10.9, Mavericks, the 35-pass erase is no longer an option. Also, there are no longer radio buttons to select how many passes to erase. There is a slider that goes from Fastest to Most Secure.
If you read my previous post about how to format an external drive for Mac, you know that I bought a 2TB Seagate Expansion external hard drive and managed to create two partitions on the disk — one for Mac backup purposes, and the other for personal use.
In this article, I’m going to show you how to back up your Mac data to an external drive. You should back up your Mac on a regular basis, especially if you’re planning to perform macOS updates.
I did this several weeks ago while preparing my MacBook Pro for a system update. You may also be interested in taking a look at the macOS Catalina slow issues we encountered during that process just in case you also want to upgrade your Mac to the latest operating system.
Please note that the backup tool that I used is Time Machine, a built-in app provided by Apple. If you want to back up your Mac data without using Time Machine, there are also other third-party Mac backup software worth considering.
Where is Time Machine on Mac?
Time Machine is a built-in app within macOS ever since OS X 10.5. To find it, click on the Apple logo on the top left corner of your screen, then select System Preferences.
In the Preferences Pane, you’ll see the app located between “Date & Time” and “Accessibility”.
What does Time Machine Backup?
Time Machine is the easiest way to back up Mac. And the app is created and recommended by Apple. Once you have a timely backup, it’s incredibly easy to restore all or part of your data in case of accidental deletion or a hard drive crash.
So, what kind of data does Time Machine backup? Everything!
Photos, videos, documents, applications, system files, accounts, preferences, messages, you name it. They all can be backed up by Time Machine. You can then restore your data from a Time Machine snapshot. To do so, first open Finder, then Applications, and click on Time Machine to continue.
Be aware that the recovery process can be only be conducted when your Mac can start up normally.
A Step-by-Step Guide to Backing up Mac to an External Hard Drive
Note: the screenshots below are taken based on an older macOS. If your Mac is running Mojave or Catalina, they will look slightly different but the process should be similar.
Step 1: Connect your external hard drive.
First, use the USB cable (or USB-C cable if you’re on the newest Mac model with Thunderbolt 3 ports) that comes with your external drive to connect that drive to your Mac.
Once the disk icon shows up on your desktop (if it doesn’t, open Finder > Preferences > General, and here make sure you’ve checked “External disks” to let them show on the desktop), move on to Step 2.
Note: if your external drive can’t show up on Mac or macOS hints the drive is not supported, you’ll have to re-format it to a Mac-compatible file system before continuing the following steps.
Step 2: Select the disk for backup.

Now open Time Machine (I tell you how above) and select the disk you want to use. I have partitioned my Seagate drive into two new volumes, “Backup” and “Personal Use”, as you see from the screenshot. I chose “Backup”.
Step 3: Confirm backup (optional).
If you have used another disk for backup before, Time Machine will ask you whether you want to stop backing up to the previous disk and use the new one instead. It’s up to you. I selected “Replace”.
Step 4: Wait until the process is complete.
Now Time Machine will start to backup all your data. The progress bar gives you an estimate of how much time is left before the backup is complete. I found it a bit inaccurate: Initially, it said “About 5 hours remaining”, but it only took two hours to finish. It’s worth noting that the remaining time may vary from case to case depending on the write speed of your external hard drive.
After about an hour and a half, it says only 15 minutes remaining
Step 5: Eject your external drive and unplug it.
When the backup procedure is completed, don’t rush to disconnect your device as this could cause potential disk problems. Instead, go back to the main desktop, locate the volume that your external hard drive represents, right-click and select Eject. Then, you can safely unplug the device and put it in a safe place.
Final Words
Mac Os X 10.7.5 External Hard Drive Recovery Software Windows 10
Like any other hardware device, an external hard drive will fail sooner or later. It’s best to make a copy of the data on your external drive — as they say, a “backup of your backups”!
One good option is to use cloud storage services like iDrive which I’ve been using and I really like the app because it’s super easy to use, and it also allows me to download Facebook photos automatically. Backblaze and Carbonite are also popular options in the market, though I am yet to give them a try.

I hope you find this tutorial helpful. I can’t emphasize enough the importance of data backup these days, especially when my mid-2012 MacBook hard drive died all of a sudden. I’ve also seen cases where my friend’s computer and hard drive failed. You can imagine their desperation. Without a proper backup, it’s really hard to restore data. Although you could try a third-party data recovery program, chances are they won’t get all your lost data back.
Anyway, the main takeaway I want you to have from this article is this: back up your Mac with Time Machine or another app, and create a second or third copy of those backups if you can.
