How to set the jumper for this WD800 drive?

The **WD800** is a Western Digital **80GB IDE (PATA)** hard drive. Like most IDE drives, it has a set of **jumper pins** that configure how the drive behaves on the IDE cable. Here's how to set it up correctly depending on your use case.

### 📌 WD800 Jumper Settings (40GB–80GB WD Caviar Series)

Look near the power and ribbon cable ports—there should be a **jumper block with 6 or 8 pins**. The jumper cap connects two pins vertically. The layout is usually labeled directly on the drive’s sticker or metal casing.

### 🔧 Jumper Modes:

| Mode | Jumper Position | When to Use |

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

| **Cable Select (CS)** | Pins 1–2 (closest to IDE port) | Preferred for modern IDE cables (uses cable to assign master/slave) |

| **Master** | Pins 3–4 | Use if it's the only drive or the main one on the cable |

| **Slave** | Pins 5–6 | Use if it's the second device on the same IDE cable |

| **Single (no jumper)** | No jumper at all | Use only if it’s the **only** device on the cable **and** no Cable Select is supported |

### 🧪 Pro Tips:

* Use **80-wire IDE cables** for better performance and Cable Select support.

* If your PC BIOS isn’t detecting the drive, try switching from **Cable Select** to **Master**.

* If you have a **CD/DVD drive on the same cable**, make sure one is **Master** and the other **Slave** (or both are CS).
