My Cloud OS5 upgrade indexing and Smart TV’s

Ah, you’ve upgraded your **WD My Cloud EX4100** to **My Cloud OS 5** and now noticing issues around **indexing** and **Smart TV streaming (DLNA/Media Server)**. This is a common pain point after the OS upgrade, so let me break it down clearly:

---

## 🔎 1. OS 5 Indexing

* When you first upgrade to OS 5, it **re-indexes all files** (photos, videos, docs).

* This can take **days or even weeks** depending on the size of your library and the drive health.

* During indexing:

* CPU runs high.

* NAS fans spin up.

* Remote access (mobile app/Web Access) might be slow or incomplete.

✅ **Tips**

* Leave the NAS powered on and connected — don’t interrupt the indexing.

* Check indexing progress in the **Admin Dashboard → Cloud Access → Status**.

* If you have many media files you don’t need cloud access for, disable cloud indexing on those shares:

* Dashboard → Shares → \[Select Share] → Cloud Access: **Off**.

## 📺 2. Smart TV & DLNA Media Streaming

Here’s where OS 5 caused some frustration for media users:

* **OS 3 (old version)** had Twonky Media Server built-in, which worked smoothly with most Smart TVs.

* **OS 5 switched** to a different **DLNA/UPnP media server** implementation.

* Many users report **Smart TVs no longer see all files**, or streaming is **slower/buggy**.

✅ **Fixes & Workarounds**

1. **Enable Media Streaming per Share**

* Dashboard → Shares → Select your media folder → **Media Serving: ON**.

* Then rescan/rebuild the media database in **Settings → Media → Rebuild**.

2. **Check Smart TV compatibility**

* Some TVs cache DLNA servers — reboot the TV and NAS if shares don’t show.

3. **Alternative Streaming Methods**

* **Plex**: Install Plex Media Server app from the WD App Store (OS 5 supports it). Plex gives much better compatibility across Smart TVs, Roku, Firestick, etc.

* **Kodi / VLC**: If your Smart TV or streaming device allows apps, use one of these to connect to the NAS via SMB or NFS instead of DLNA.

## ⚠️ Key Difference OS 3 vs OS 5

* **OS 3:** Better for simple home media (DLNA/Twonky worked great).

* **OS 5:** Designed more for **remote/cloud access**, less emphasis on local Smart TV streaming.

* If your priority is **Smart TV media streaming**, Plex is often the best long-term solution.
