What You’ll Need Before Starting

Before you open up your HomeBase 3, make sure you have the right tools and components. Rushing into the process without preparation can lead to mistakes or damage. Here’s a checklist to get you started:

Compatible Hard Drive

The Eufy HomeBase 3 supports **2.5-inch SATA hard drives (HDDs) or solid-state drives (SSDs)** with a maximum capacity of **8TB**. It does not support 3.5-inch desktop drives due to size and power limitations.

When choosing a drive, consider:
– **SSD vs. HDD**: SSDs are faster, quieter, and more reliable because they have no moving parts. They’re ideal for 24/7 recording. HDDs are cheaper per gigabyte but generate more heat and may wear out faster.
– **Brand recommendations**: Reliable brands include Samsung, Crucial, WD (Western Digital), and Seagate. For SSDs, the Samsung 870 QVO or Crucial MX500 are excellent choices.
– **Capacity**: A 1TB drive can store about 7–10 days of continuous footage from multiple cameras, depending on resolution and motion settings. For longer retention, go with 2TB, 4TB, or even 8TB.

Tools Required

You’ll need just a few basic tools:
– A **small Phillips-head screwdriver** (usually #0 or #1 size)
– A clean, flat workspace (like a table or desk)
– Optional: Anti-static wrist strap (to prevent static damage to components)

Backup Existing Data (If Any)

If your HomeBase 3 already has a hard drive installed, **back up any important footage** before proceeding. Installing a new drive will **erase all existing data** during the formatting process. You can download clips via the Eufy Security app before starting.

Ensure Stable Power and Internet

Make sure your HomeBase 3 is plugged into a power outlet and connected to your Wi-Fi network. The setup process requires the Eufy app, which needs an internet connection to communicate with the device.

Step-by-Step Guide: Installing the Hard Drive

Now that you’re prepared, let’s get into the actual installation. Follow these steps carefully to avoid damaging your device.

Step 1: Power Down the HomeBase 3

Safety first! Before opening the device, **unplug the power adapter** from the back of the HomeBase 3. Wait about 30 seconds to ensure all internal components are fully powered down.

Never attempt to open the device while it’s plugged in—this could cause electrical shock or damage the circuitry.

Step 2: Remove the Bottom Cover

Flip the HomeBase 3 upside down so the bottom panel is facing up. You’ll see four rubber feet—these hide the screws underneath.

– Gently peel back each rubber foot using your fingernail or a small flat tool.
– Use your Phillips-head screwdriver to remove the four screws.
– Set the screws and rubber feet aside in a small container so you don’t lose them.

Once the screws are out, carefully lift the bottom cover. It should come off easily—no clips or glue hold it in place.

Step 3: Locate the Drive Bay

Inside, you’ll see the internal layout of the HomeBase 3. The hard drive bay is located near the center, connected to the mainboard via a SATA data and power cable.

If there’s already a drive installed, disconnect it by gently pulling the SATA connectors straight out (don’t yank or twist).

Step 4: Install the New Hard Drive

Now it’s time to install your new drive:

1. Place the 2.5-inch drive into the bay with the SATA ports facing toward the rear of the device.
2. Align the drive so the screw holes on the sides match the mounting points in the bay.
3. Secure the drive using the included screws (or reuse the old ones if they fit). Tighten them snugly—don’t over-tighten, as this can strip the plastic housing.
4. Connect the SATA data cable to the drive’s data port.
5. Connect the SATA power cable to the drive’s power port.

Both cables should click in gently. If they don’t fit, double-check the orientation—SATA connectors are keyed and only fit one way.

Step 5: Reassemble the HomeBase 3

Once the drive is securely installed and connected:

1. Place the bottom cover back onto the device.
2. Reinsert the four screws and tighten them.
3. Replace the rubber feet over the screw heads.

Make sure everything is snug and the device sits flat on the table.

Step 6: Power On and Initialize

Plug the power adapter back into the HomeBase 3 and turn it on. The device will boot up and detect the new drive automatically.

You’ll see a solid blue light on the front, indicating it’s ready. If the light is blinking or red, there may be an issue—we’ll cover troubleshooting later.

Setting Up the Drive in the Eufy Security App

Now that the hardware is installed, it’s time to configure the drive using the Eufy app. This step is crucial—without it, the system won’t recognize or use the new storage.

Open the Eufy Security App

Launch the Eufy Security app on your smartphone or tablet. Make sure you’re logged into the same account used to set up your HomeBase 3.

Navigate to Device Settings

1. Tap on the **HomeBase 3** device from the home screen.
2. Tap the **gear icon** (settings) in the top-right corner.
3. Scroll down and select **Storage Settings**.

Format the New Drive

You’ll see a prompt saying a new drive has been detected. Tap **Format** to begin the process.

⚠️ **Important**: Never format the drive on a computer using Windows or macOS. The Eufy system uses a proprietary file system, and formatting externally will cause errors. Always use the app.

The formatting process takes 1–5 minutes, depending on drive size. You’ll see a progress bar—do not interrupt it.

Confirm Successful Installation

Once formatting is complete, the app will show the drive’s capacity and status (e.g., “Healthy” or “Ready”). You can now enable **local recording** for your cameras.

Go back to each camera’s settings and toggle on **Local Recording**. You can choose between:
– **Continuous Recording**: Saves all footage 24/7.
– **Motion-Only Recording**: Saves clips only when motion is detected (saves space).

Tips for Optimal Performance

To get the most out of your new hard drive setup, follow these best practices:

Use an SSD for Better Reliability

While HDDs work, SSDs are better suited for 24/7 security systems. They handle constant read/write cycles more efficiently and are less prone to mechanical failure.

Monitor Drive Health

Check the drive status in the Eufy app regularly. If you see warnings like “Drive Error” or “Low Space,” it’s time to back up and replace the drive.

Manage Storage Wisely

Set recording modes based on your needs:
– Use **motion-only recording** if you only need alerts and event clips.
– Use **continuous recording** if you want full coverage (e.g., for evidence or monitoring pets).

You can also set **retention periods**—older footage is automatically deleted when space runs low.

Keep the HomeBase 3 Cool

Hard drives generate heat. Place your HomeBase 3 in a well-ventilated area, away from direct sunlight or heat sources. Avoid stacking other devices on top.

Update Firmware Regularly

Eufy releases firmware updates that improve performance and compatibility. Enable auto-updates in the app settings to stay current.

If the Eufy app doesn’t recognize the new drive:
– Double-check SATA connections—ensure both data and power cables are fully seated.
– Try reseating the drive and reconnecting cables.
– Power cycle the HomeBase 3 (unplug for 30 seconds, then plug back in).

Formatting Fails

If the app says “Format Failed”:
– The drive may be incompatible. Confirm it’s a 2.5-inch SATA drive under 8TB.
– Try a different drive if possible.
– Reset the HomeBase 3 to factory settings (via app > Settings > Reset) and retry.

Red or Blinking Light

A red or blinking light indicates an error:
– Solid red: Hardware issue (e.g., faulty drive or connection).
– Blinking red: System error or update in progress.
