WD My Passport for Mac drives are formatted in HFS+ or APFS and are designed to auto-mount on macOS when connected via USB-A or USB-C. When the drive is not showing up on the desktop or in Finder, the cause ranges from a loose cable to a drive needing First Aid or, in serious cases, physical failure. This guide covers every fix in order of likelihood.
Part 1. Check Disk Utility First (Before Anything Else)
The drive may be detected by macOS but failing to auto-mount. Disk Utility reveals drives that are present but unmounted.
Steps:
- Open Finder → Applications → Utilities → Disk Utility.
- Click View → Show All Devices (top-left of Disk Utility toolbar).
- Look for your WD My Passport in the left panel.
| What You See | What It Means |
|---|---|
| Drive appears, volume greyed out | Volume exists but is not mounted — click Mount |
| Drive appears but shows no volume | Partition table may be damaged |
| Drive does not appear at all | Not detected by macOS — hardware/cable issue |
| Drive appears with a red First Aid icon | File system errors — run First Aid |
💡 Tip: If the drive appears in "Show All Devices" but not under "Locations" in Finder, the issue is a mount failure rather than a detection failure. Click the drive volume and press the Mount button in Disk Utility's toolbar.
If the drive does not appear at all even in "Show All Devices," proceed to Part 2.
Part 2. Check Cable, Port, and Power
The most common reason for a My Passport not showing up is a faulty USB connection. My Passport drives draw power from the USB port — a poor connection causes the drive to spin up and immediately drop.
Checklist:
- Try a different USB cable (use the original WD cable or a known-good USB-C/USB-A cable)
- Try a different USB port on your Mac
- Connect directly to the Mac — avoid USB hubs, especially unpowered ones
- If using a USB-C hub or dongle, bypass it and connect the drive directly to a Mac port
- Try the drive on a different computer to confirm the drive itself works
⚠️ Important: WD My Passport drives do not have external power adapters. They rely entirely on the USB port for power. Some USB hubs do not supply enough current (500 mA minimum required) to spin up the drive reliably. Always test with a direct Mac connection before assuming the drive is faulty.
If the drive shows the activity light but still does not appear in Disk Utility, proceed to Part 3.
Part 3. Reset NVRAM and Re-Check
NVRAM (Non-Volatile RAM) stores certain macOS settings including USB device behavior. A corrupted NVRAM can sometimes cause external drives to fail to mount.
Reset NVRAM on Intel Mac:
- Shut down your Mac completely.
- Turn it on and immediately press and hold Option + Command + P + R.
- Hold for about 20 seconds until you hear the startup sound twice (or see the Apple logo appear and disappear twice on newer Macs).
- Release and let the Mac boot normally.
- Reconnect the My Passport drive.
Apple Silicon Mac: NVRAM resets automatically during startup on M-series Macs. Simply restart the Mac and reconnect the drive.
🗣️ r/applehelp user: "My WD Passport suddenly stopped appearing after a macOS update. NVRAM reset fixed it completely. Took 2 minutes and the drive was back. No idea why it worked but it did."
After the reset, also check System Settings → General → Storage to confirm the drive is not being hidden by a Finder preference.
Part 4. Run First Aid on the Drive
If the drive appears in Disk Utility but shows errors or refuses to mount, First Aid can repair the file system.
Steps:
- Open Disk Utility and select the WD My Passport (select the volume, not just the container).
- Click First Aid in the toolbar.
- Click Run and wait for the scan to complete.
- If First Aid reports errors: try Unmount then Mount after the repair.
Common First Aid results and what they mean:
| Result | Action |
|---|---|
| "The volume appears to be OK" | Drive is healthy; mount issue may be permissions-related |
| "Errors were found and repaired" | Repair succeeded; eject and reconnect the drive |
| "Errors were found but could not be repaired" | File system too damaged; attempt data recovery before further steps |
| "The volume could not be unmounted" | A process is using the drive; quit all apps, then retry |
💡 Tip: If First Aid says it could not repair the drive, do not immediately reformat. Reformatting at this point would overwrite your data. Use data recovery software first to retrieve your files before reformatting.
Part 5. Check Finder Preferences and External Drive Visibility
macOS may be configured to hide external drives from the desktop and Finder sidebar.
Steps:
- Open Finder → Settings (Cmd+,).
- In the General tab, check External disks under "Show these items on the desktop."
- In the Sidebar tab, check External disks under Locations.
This does not fix an unmounted drive but will make a properly mounted drive visible in Finder after the fixes in Parts 1–4 succeed.
🗣️ r/MacOS user: "Spent 30 minutes troubleshooting my WD drive not appearing. Turned out I had disabled external disks in Finder preferences months ago and forgotten. The drive was mounted fine the whole time — just invisible."
Part 6. Recover Files If the Drive Is Inaccessible
If Disk Utility detects the drive but First Aid cannot repair it, or if the drive mounts briefly and then disconnects, recovering your files should be the immediate priority before any further repair or reformat.
Ritridata can scan WD My Passport drives that are partially accessible or showing file system errors, and recover files that are still readable at the sector level. Connect the drive, run a Ritridata scan, and save recovered files to a different drive — then proceed with reformatting the My Passport.
FAQ
Q: Why does my WD My Passport for Mac keep disconnecting? A: Intermittent disconnections are usually caused by an insufficient USB power supply (use a direct Mac port, not a hub), a failing USB cable, or early signs of drive hardware failure. If disconnections persist with a direct connection and new cable, the drive may be failing.
Q: My Passport works on Windows but not on Mac — why? A: A My Passport formatted as NTFS (Windows default) mounts as read-only on macOS by default. A Mac-formatted drive (HFS+ or APFS) cannot be read by Windows at all. If the drive is NTFS and you need read/write on Mac, use Paragon NTFS for Mac or reformat to exFAT for cross-platform access.
Q: Disk Utility shows my My Passport as "Untitled" or with a different name — is that normal? A: An empty or reformatted drive may show as "Untitled." If the drive was previously named and now shows "Untitled," the volume name metadata may have been reset — this is not necessarily a sign of data loss.
Q: Can I use Time Machine with a WD My Passport for Mac? A: Yes. WD My Passport drives formatted as APFS or HFS+ work with Time Machine. When you connect the drive for the first time, macOS asks if you want to use it as a Time Machine backup. Choose "Use as Backup Disk" to set it up.
Q: How do I safely eject a WD My Passport from Mac? A: Right-click the drive in Finder or Disk Utility and select Eject. Always eject before physically disconnecting. Pulling the cable while the drive is being written to can cause file system corruption.
