Fix 5: Reformat the Drive

Reformatting your WD external hard drive can resolve file system errors or compatibility issues that prevent macOS from recognizing the device. However, it's important to note that reformatting will erase all data on the drive. If the data is valuable, consider using recovery software to retrieve it before proceeding.

Why Reformatting Works

Reformatting a drive essentially prepares it to work with a specific operating system or file system by erasing all current data and rewriting the structure. Many WD external hard drives come preformatted with the NTFS file system, which is optimized for Windows. While macOS can read NTFS drives, it cannot write to them without additional software. Reformatting the drive to a macOS-compatible format eliminates potential issues caused by incompatibility.

Steps to Reformat the Drive

1. Access Disk Utility
   • Open Disk Utility from Applications > Utilities, or search for it using Spotlight.
   • From the top-left menu in Disk Utility, select View > Show All Devices to ensure all connected drives are visible.
2. Select the Drive
   • In the Disk Utility sidebar, locate your WD external hard drive. It might appear as an unmounted volume or under a different name.
   • Be sure to select the top-level drive (not just the partition).
3. Choose Erase
   • With the drive selected, click the Erase button at the top of the Disk Utility window.

   • A pop-up window will appear, asking for formatting details.
4. Configure Formatting Options
   • Name: Enter a name for the drive (e.g., "My WD Drive").
   • Format: Select a macOS-compatible file system:
     • APFS: Best for macOS-only usage, offering faster speeds and better encryption.
     • Mac OS Extended (Journaled): Compatible with older versions of macOS.
     • ExFAT: Ideal for cross-platform use between Mac and Windows.
   • Scheme: Choose GUID Partition Map for macOS compatibility.
5. Erase the Drive
   • Click Erase to begin the reformatting process.

   • Wait for Disk Utility to finish erasing and reformatting the drive. This process may take a few minutes.
6. Verify the Drive
   • Once the reformatting process is complete, the drive should appear in Disk Utility and Finder.
   • Test the drive by transferring a small file to confirm it’s functioning correctly.

When to Reformat a Drive

Reformatting is recommended in the following scenarios:

• The drive is preformatted for Windows and you plan to use it primarily with macOS.
• The drive is accessible but has frequent errors or corrupt files.
• Disk Utility recognizes the drive but cannot mount it due to file system issues.

Precautions Before Reformatting

• Backup Data: If the drive contains important files, back them up to another device or use data recovery software.
• Choose the Right Format: Consider how you plan to use the drive. For instance, ExFAT is better if you frequently switch between Mac and Windows.
• Understand the Risks: Reformatting cannot fix physical damage or severe hardware failure.

By carefully following these steps, you can resolve many recognition issues caused by incompatible or corrupted file systems on your WD external hard drive.

💡 Note:

• If you lost data due to reformatting your WD external hard drive, you can use Mac data recovery software to deeply scan the WD external hard drive and get all lost files back.
• If you don't want to reformat the WD external hard drive, you can install an NTFS driver - such as Donemax NTFS for Mac, then open it, select the NTFS drive, click on Enable Writable button. After this, you can use NTFS drive on your Mac without any limitation.

2. Type diskutil list and press Enter. This command lists all connected drives, including unmounted ones.

3. If your WD drive appears in the list, type diskutil mountDisk [disk identifier] to manually mount it. Replace [disk identifier] with the appropriate ID from the list.

Fix 8: Try Safe Mode

Booting your Mac into Safe Mode disables unnecessary processes and drivers that might interfere with external drives:

1. Restart your Mac and hold the Shift key while it boots.
2. Once in Safe Mode, connect your WD drive.
3. If the drive appears, restart your Mac normally and check again.

If you are a Mac with M-chip, press and hold Power button until your Mac starts into macOS Recovery mode. Then select Macintosh HD, press Shift, then click Continue in Safe Mode.
