As described (LED lights but no drive letter), the symptom usually narrows to a few safe-to-check categories: USB power/cable/port issues, the OS not enumerating the disk (driver/letter/partition problems), software/locking from WD utilities, or mechanical/controller failure. This note expands on and with practical, non‑destructive steps and cautions.

Recommended non‑destructive checks and quick triage:

  • Physical/cable/power: swap the USB cable and use a different port (prefer a back‑panel port on a desktop). A powered USB hub can rule out low current from a single port.
  • Cross‑platform test: connect the drive to another machine (Windows, macOS, or a Linux live USB). Different OSes sometimes expose a drive that one OS hides.
  • Listen and observe: a steady spin/hum is different from repeated clicking or no spin. Clicking usually indicates hardware failure and further use risks data loss.
  • Windows diagnostics: open Disk Management (diskmgmt.msc). If the disk appears without a drive letter, assign one. If it shows “Not Initialized” or RAW, avoid initializing/formatting when data is important — initializing will overwrite the partition table.
  • Device Manager and USB stack: check for unknown devices or errors under Disk drives and USB controllers; uninstalling the device entry and replugging can force a fresh enumeration. Disable USB power‑saving for hubs if ports drop power.
  • WD software/lock: some My Passport models expose a small virtual CD or require WD Unlocker/WD Security to access an encrypted volume. If such a volume appears, unlocking is required before the main volume mounts.

If the drive reports mechanical faults, produces clicking, or the partition table is gone and the data is valuable, stop risky actions (no formats). Imaging the disk first (read‑only) and using recovery tools or a professional recovery service is the safest path. Opening a sealed My Passport enclosure voids warranty and is generally not recommended. This guidance complements ’s and ’s points while prioritizing data safety.

I assume you are not using an external power supply, but are depending upon the USB port to provide adequate power for the device? If so, that is not a good idea. On most computers only 1 or 2 ports have enough power for a hard drive. Try it with the external power supply.

I have used a passport, and it required additional software. Not sure if that's still the case. Did you install anything?
