Transferring old passport in Windows to new passport for MAC

Switching from a Windows PC to a Mac is an exciting upgrade, but many users wonder how to transfer files from an old WD My Passport for Windows drive to a WD My Passport for Mac. Fortunately, the process is straightforward if you understand the differences in file systems and compatibility.

This guide explains how to safely transfer your data, prepare your new drive, and ensure your files remain accessible on your Mac.

Understanding the Difference Between WD My Passport for Windows and Mac

Although both drives are physically similar, they are formatted differently:

WD My Passport for Windows is usually formatted with NTFS, which Windows can read and write. macOS can read NTFS drives but cannot write to them without additional software.

WD My Passport for Mac is typically formatted with APFS or HFS+ (Mac OS Extended), which is optimized for macOS.

The good news is that you can still copy files from your old Windows-formatted drive to your Mac without any special tools.

Before You Begin

Before transferring your data, make sure you have:

Your old WD My Passport drive

Your new WD My Passport for Mac

A Mac computer with enough available storage

USB cables for both drives

A stable power source if transferring a large amount of data

If your Mac has only USB-C ports, you may need a compatible adapter or USB-C cable.

Step 1: Connect the Old WD My Passport Drive

Plug your Windows-formatted My Passport into your Mac.

macOS should automatically recognize the drive. Since NTFS is readable on macOS, you can open the drive and view all your files.

If the drive doesn't appear:

Disconnect and reconnect it.

Try another USB port.

Restart your Mac.

Open Disk Utility to check if the drive is detected.

If the drive appears in Disk Utility but not in Finder, you may need to mount it manually.

Step 2: Connect the New WD My Passport for Mac

Now connect your new My Passport for Mac.

The drive should appear in Finder.

If it's brand new, it should already be formatted correctly for macOS.

If not, you can reformat it using Disk Utility.

To format the drive:

Open Applications > Utilities > Disk Utility

Select the new drive.

Click Erase.

Choose:

APFS (recommended for macOS 10.13 and later)

or Mac OS Extended (Journaled) for older Macs.

Click Erase.

Warning: Formatting permanently deletes everything on the drive.

Step 3: Copy Your Files

Open two Finder windows:

One showing the old Passport drive.

Another showing the new Passport for Mac.

Select the folders you want to transfer.

Examples include:

Documents

Photos

Videos

Music

Work files

Downloads

Backups

Simply drag and drop the files onto the new drive.

The transfer time depends on:

Total file size

USB speed

Number of files

Drive performance

Large transfers may take several hours.

Avoid disconnecting either drive until the copy process has completed.

Step 4: Verify the Transfer

Once the transfer is complete:

Open several folders.

Preview photos.

Play videos.

Open important documents.

Compare folder sizes.

Verifying your files ensures the transfer completed successfully.

Do not erase your old drive until you've confirmed every important file has been copied.

Using Migration Assistant (Optional)

If you're moving from a Windows PC to a Mac for the first time, Apple provides Migration Assistant.

Migration Assistant can transfer:

Documents

Photos

Music

User accounts

Contacts

Calendars

Email settings

However, if your files are already stored on your WD Passport drive, manually copying them is often faster and simpler.

What About WD Discovery?

WD Discovery is Western Digital's management software.

It can help you:

Register your drive

Install backup software

Update firmware

Access cloud services

However, WD Discovery is not required for transferring files between drives.

Finder can copy files directly without additional software.

Can You Transfer Everything?

Yes, most personal files transfer without any issues.

These include:

Word documents

Excel spreadsheets

PDF files

Photos

Videos

Music

ZIP archives

Project files

Some Windows-specific applications and programs cannot simply be copied to macOS because they require separate Mac-compatible versions.

Common Problems and Solutions

Mac Cannot See the Old Drive

Possible causes include:

Faulty USB cable

Damaged USB port

Drive corruption

Insufficient power

Try another cable or USB port.

Open Disk Utility to determine whether the drive is recognized.

Permission Errors

Sometimes copied files are marked as read-only.

To fix this:

Select the file.

Choose Get Info.

Adjust Sharing & Permissions if necessary.

Transfer Is Extremely Slow

Slow transfers may occur because of:

USB 2.0 connections

Very large files

Thousands of small files

Background applications

Closing unnecessary apps may improve performance.

Files Are Missing

If some folders do not appear:

Check hidden files.

Search using Finder.

Compare used storage on both drives.

Avoid formatting the old drive until everything has been verified.

Tips for a Smooth Transfer

For the best experience:

Keep both drives connected throughout the process.

Avoid putting your Mac to sleep during the transfer.

Safely eject both drives after copying.

Maintain a backup of important files.

Organize folders before moving them.

Verify important documents after copying.

Should You Reformat the Old Passport?

Once you've confirmed all your files are safely stored on the new My Passport for Mac, you may reformat the old drive.

If you plan to use it only with Macs, format it as APFS.

If you'll continue using both Windows and macOS, consider formatting it as exFAT, which offers read and write compatibility with both operating systems.

Final Thoughts

Transferring data from an old WD My Passport for Windows to a WD My Passport for Mac is a simple process that primarily involves copying files from one drive to another. macOS can read NTFS-formatted Windows drives, making it easy to access your existing data without installing additional software. After preparing your new drive, carefully copy your files, verify the transfer, and keep the old drive intact until you're certain everything has been moved successfully.

By following these steps, you can migrate your documents, photos, videos, and other important files safely while ensuring your new Mac-compatible drive is ready for everyday use.
