PR4100 Not showing all my files and folders online

Got it 👍 — your WD My Cloud PR4100 isn’t showing all your files and folders when you access it online. That usually happens after firmware updates, indexing issues, permission settings, or cloud sync glitches. Let’s troubleshoot step by step:

🔍 Possible Causes

Indexing / Crawler not finished

After a reboot, firmware update, or OS5 migration, the PR4100 scans and indexes your files for remote/web access. Until it completes, not all folders may appear online (but they’ll still exist on the drive).

Private vs. Public Shares

Some shares may be set to Private. Unless your user account has permission, they won’t show up online.

Cloud Access Sync

Sometimes a share is created but not enabled for cloud access. That makes it invisible on mycloud.com or the mobile app.

File system or volume issues

Corrupted indexes or drive health problems can cause missing/misaligned folders.

Cache / Browser issue

Old cached metadata may prevent new files from displaying correctly online.

🛠 Fix Steps

1. Check if the files are there locally

Access your PR4100 directly on your LAN via:

Network share (SMB) in Windows Explorer:

\\<NAS-Name> or \\<IP-Address>

macOS Finder → Go → Connect to Server → smb://<IP-Address>

If you see all your files locally, then the problem is cloud indexing/sync, not data loss.

2. Confirm Shares are Cloud-Enabled

Log into the PR4100 Dashboard (http://<NAS-IP>/).

Go to Shares.

Pick the missing folder → ensure Cloud Access = ON.

Assign your user account cloud access to that share.

3. Rebuild/Re-Enable Cloud Access

In Dashboard → Cloud Access:

Disable Cloud Access for your user → Save.

Re-enable it and wait for it to resync.

Sometimes this forces a refresh.

4. Wait for Indexing

In OS5, indexing can take hours or days depending on library size.

Go to Settings → General → Cloud Access and check indexing status.

If “Content is being indexed,” missing folders should eventually appear.

5. Clear Cache / Use Another Method

Log out of mycloud.com and back in.

Clear browser cache or try incognito mode.

Try the My Cloud OS5 mobile app (Android/iOS) to see if the files show up.

6. Disk Health Check

In Dashboard → Storage → Disk Status.

Run a disk scan to rule out drive issues.

⚠️ Last Resort

If none of the above works:

SSH into the NAS (if you’re comfortable) and check if files physically exist under /shares/ or /mnt/HD/HD_a2/.

Contact WD support if the issue persists after indexing completes, as it may be a corrupted database.

👉 Do you want me to guide you on how to check if indexing is still running on your PR4100? That’s often the main reason files don’t show up online after an update.
