Format WD My Passport On Mac Frequently Asked Questions

1. How Can I Format My WD My Passport Drive For Resale?

You should be aware that:

The formatting procedure above will not stop someone using specialized data recovery software. And use that software to recover your documents from your old My Passport hard drive.

If you’re planning on reselling your My Passport drive you’ll need the formatting to go deeper.

When You Format Your My Passport Drive you Should;

In Disk Utility when you select the erase option.  

Click on the security button.

Format Security Options buttons
Format Security Options Button

Select one of the security options there. And format your WD Passport drive using one of those options. It could take several hours to fully write over the drive.

It’ll be worth it.

As you’ll erase as much of your data as possible.

And at least you can rest easier. And know it will take way more effort to recover anything from your sold My Passport hard drive.

2. How To Set Up Encryption And A password To Secure Your My Passport Hard Drive.

WD My Passport has 256-bit AES hardware encryption. Along with password protection for the drive. The WD Security software controls and manages the hardware encryption.

You won’t find a copy of the WD Security software on the WD My Passport – non Mac.

But you can download the Mac version direct from the Western Digital website.

You might not want to when I describe a possible situation. And prefer to use the options provided by Mac OS for encrypting your hard drive. And to use Mac OS to add a password.


Because, without the WD Security software installed. And accessible by your Mac, you can’t get to your documents on your My Passport drive.

Plus when you share your My Passport drive between several Macs, the software must be on those Macs as well.

Let me paint a situation for you.

Imagine your Mac has failed. And you’re desperate for your backup. But wait the backup you need is on the My Passport drive. And to get to that backup you need the WD Security software installed.

But your Mac is wiped. You need your Mac’s backup to get to the WD security software.

You see the problem?

You’re then in an almighty bind. And this exact situation has happened.

Mac OS will always recognize its own encryption and password methods.

You can encrypt your data. And set a password by selecting Mac OS Extended (Journaled, Encrypted) file system.

4. You’re Having Problems Formatting An External Hard Drive Since Upgrading To High Sierra.

There have been quite a lot of discussions on various forums with many people having problems formatting hard drives. And this follows an upgrade to Mac OS High Sierra.

I am sure Apple will produce a fix soon. But in the mean time to format My Passport for Mac try these suggestions.

a. If the My Passport hard drive icon doesn’t appear on the desktop when you plug in. Go to Disk Utility and expand the external hard drive list there (step 4 above). If your My Passport drive shows up in the list go ahead and format.

b. Use a Windows PC to format your WD My Passport drive first to ExFAT. Then try again on the Mac.

c. Use a Mac with an older release of Mac OS to format your WD Passport drive.

d. Download the WD Discovery software for Mac from the Western Digital site. This software allows you to check the disk health and you can format to HFS using that software.

There are other options which are more complex if the above has not worked for you. Check out my resources section below to see the discussion threads.
