How to set the jumper for this WD800 drive?

Got it 👍 — the **WD800** (Western Digital 80 GB) is a **3.5-inch IDE (PATA)** hard drive, and its jumper settings depend on how you plan to connect it — as **Master**, **Slave**, or **Cable Select (CS)** on an IDE ribbon cable.

Here’s how to set the jumper correctly:

---

### 🧷 Jumper Block Layout

Looking from the **back of the drive**, where the connectors are:

```

|:::::::|:::::::|:::::::|:::::::|

| PWR | IDE | JUMPERS |

```

On the **right side**, near the IDE connector, you’ll see **a small 8-pin jumper block** (2 rows × 4 pins).

### ⚙️ Jumper Settings for WD800

| Mode | Pins | Description |

| ------------------------------------------ | ----------------------- | ------------------------------------------------------------------ |

| **Single Drive** (only one drive on cable) | **No jumper installed** | Leave the jumper block empty. |

| **Master with Slave Present** | **Pins 5–6** | Use when you have two drives on one IDE cable. |

| **Slave Drive** | **Pins 3–4** | Use this when the other drive is the master. |

| **Cable Select (CS)** | **Pins 1–2** | Lets the IDE cable position decide (end = Master, middle = Slave). |

### 📘 Quick Visual Reference (Viewed from back of drive)

```

+----------------------------+

1–2 Cable Select

3–4 Slave

5–6 Master

(no jumper = Single)

```

### 🧩 Tips

* **Use Cable Select (CS)** if your system and cable support it — most Dell, HP, and newer IDE systems do.

* If the system doesn’t recognize the drive, try switching between **CS** and **Master**.

* Ensure the **IDE ribbon cable’s red stripe** is aligned with **Pin 1** (closest to the power connector).
