How to Set the Jumper for this WD800 drive?

Here’s a diagram of Western Digital jumper configurations for SATA and PATA (EIDE) drives to help you locate and understand the jumper block on your WD800 drive.

### Identifying Your Drive Type

First, determine whether your WD800 is a **SATA** or **PATA (IDE)** drive:

* **SATA drives** typically don’t require jumper settings for Master/Slave configurations since each runs on its own cable. Jumpers may be used only for specific advanced features.([Western Digital][1], [\[H\]ard|Forum][2])

* **PATA (IDE) drives** use jumpers to set Single, Cable Select, Master, or Slave modes.([docs.rs-online.com][3], [eshop.macsales.com][4])

### SATA Drive Jumper Options (if applicable)

If your WD800 is SATA:

* No jumper is needed for standard desktop use (default).

* Optional settings (depending on the model):

* **Spread Spectrum Clocking (SSC)**: jumper on pins 1–2 to **disable** (default, no jumper) or **enable** SSC.([B\&H Photo Video][5], [eshop.macsales.com][4])

* **PM2 Mode**: jumper on pins 3–4 for controlled spin-up, used in server environments.([B\&H Photo Video][5])

* **OPT1**: jumper on pins 5–6 to force SATA to 1.5 Gb/s compatibility (if needed).([B\&H Photo Video][5], [Western Digital][1])

### PATA (IDE) Drive Jumper Configuration (if applicable)

If your WD800 is an older IDE model:

* **Default factory setting** is typically **Cable Select (CSEL)**.([docs.rs-online.com][3], [eshop.macsales.com][4])

* If your system doesn’t support CSEL, configure manually using:

* **Single drive** (only device on the cable): jumper on pins **4 & 6**.([docs.rs-online.com][3])

* **Master (primary)** drive (with another device on the same cable): jumper on pins **5 & 6**.([docs.rs-online.com][3])

* **Slave (secondary)** drive: jumper on pins **3 & 4**.([docs.rs-online.com][3])

Keep in mind: if another drive on the cable is set to CSEL or Master, your new drive must be set to Slave (or match the configuration accordingly) for proper detection.([eshop.macsales.com][4])

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

| SATA | Default/desktop | None |

| SATA | SSC enable/disable | 1–2 |

| SATA | PM2 mode | 3–4 |

| SATA | OPT1 mode (1.5 Gb/s) | 5–6 |

| PATA | Single drive | 4–6 |

| PATA | Master (primary) | 5–6 |

| PATA | Slave (secondary) | 3–4 |

| PATA | Cable Select (CSEL) | Default setting |

### What to Do Next

1. **Check your WD800 drive label** to confirm whether it's IDE or SATA.

2. **Refer to the included diagram** and drive label for exact jumper locations.

3. **Select the desired mode** based on your setup using the table above.

4. **Connect cables accordingly** (especially for PATA—use the black connector for Master, grey for Slave, or a Cable Select cable).

5. **Power on and check BIOS** to ensure the drive is detected correctly.
