How to Install Hard Drive in Eufy HomeBase 3

If you’re using the Eufy HomeBase 3 as the brain of your home security system, you already know how powerful and reliable it is. It supports multiple Eufy cameras, offers local storage, and keeps your data private—no monthly fees required. But what if you want to record more footage, keep videos longer, or enable 24/7 recording? That’s where installing a hard drive comes in.

The Eufy HomeBase 3 has a built-in drive bay that lets you add a 3.5-inch SATA hard drive for expanded local storage. Whether you’re upgrading from the default 1TB drive or installing one for the first time, this guide will walk you through the entire process—from choosing the right drive to formatting it and troubleshooting common issues.

By the end of this guide, you’ll know exactly how to install a hard drive in Eufy HomeBase 3 safely and correctly. We’ll cover everything you need: compatible drives, tools, step-by-step instructions, app setup, and tips to keep your system running smoothly. Let’s get started!

Why Install a Hard Drive in Your Eufy HomeBase 3?

Before we dive into the installation, let’s talk about why adding a hard drive is a smart move.

The Eufy HomeBase 3 comes with 1TB of internal storage, which is decent for basic use. But if you have multiple cameras or want to record continuously, that space fills up fast. A motion-triggered recording might only save clips when activity is detected, but 24/7 recording captures everything—day and night. That requires a lot more storage.

By installing a hard drive, you can:
– Store weeks or even months of footage
– Enable continuous recording on all connected cameras
– Avoid overwriting old clips too quickly
– Keep your data private and secure on your local network

Plus, since Eufy doesn’t require cloud subscriptions, using a hard drive is a cost-effective way to scale your system. You get full control over your recordings without recurring fees.

What Hard Drive Should You Use?

Not all hard drives are created equal—especially when it comes to security systems. The Eufy HomeBase 3 supports 3.5-inch SATA hard drives up to 16TB in capacity. But for best performance and reliability, you should choose a drive specifically designed for surveillance use.

Recommended Drive Types

Look for drives labeled as “surveillance-grade” or “optimized for 24/7 operation.” These are built to handle constant writing and reading, unlike regular desktop drives that can fail under heavy use.

Top brands include:
– WD Purple: Designed for surveillance, with AllFrame technology to reduce video frame loss.
– Seagate SkyHawk: Built for 24/7 workloads, with ImagePerfect firmware for smooth video streaming.
– Toshiba S300: High-capacity option with vibration resistance for multi-drive environments.

Avoid using old or consumer-grade drives (like WD Blue or Seagate Barracuda) unless absolutely necessary. They’re not built for constant recording and may fail prematurely.

Capacity Options

The HomeBase 3 supports drives from 1TB up to 16TB. Here’s a rough estimate of how long footage will last based on capacity and number of cameras:

– 1TB: ~7 days of 24/7 recording with 2 cameras
– 4TB: ~28 days with 2 cameras
– 8TB: ~56 days with 2 cameras
– 16TB: ~112 days with 2 cameras

These numbers can vary based on video quality, motion detection settings, and camera resolution. Higher resolution (like 2K or 4K) uses more storage.

Important Notes

– The drive must be unformatted or blank. The HomeBase 3 will format it during setup.
– Do not use external USB drives—only internal 3.5-inch SATA drives are supported.
– SSDs are not recommended due to cost and unnecessary performance for this use case.

Tools and Materials You’ll Need

Before you begin, gather these items:

• Compatible 3.5-inch SATA hard drive (e.g., WD Purple 4TB)
• Phillips-head screwdriver (size #2 recommended)
• Clean, flat workspace (like a table or desk)
• Anti-static wrist strap (optional but recommended)
• Soft cloth or towel (to protect the device)

Make sure your workspace is well-lit and free of dust. Static electricity can damage electronics, so avoid working on carpet and consider using an anti-static mat or wrist strap.

Step-by-Step: How to Install Hard Drive in Eufy HomeBase 3

Now that you’ve got your drive and tools ready, let’s install it. Follow these steps carefully to avoid damage and ensure a smooth setup.

Step 1: Power Down the HomeBase 3

Safety first! Before opening the device, you must disconnect it from power.

• Unplug the power adapter from the wall outlet.
• Wait at least 30 seconds to ensure all power is drained.
• Place the HomeBase 3 on a soft surface to prevent scratches.

Never open the device while it’s powered on. Doing so could damage the internal components or cause data corruption.

Step 2: Locate the Hard Drive Bay

The hard drive bay is located on the bottom of the HomeBase 3. You’ll see a rectangular panel held in place by four screws.

• Turn the device upside down so the bottom is facing up.
• Look for the panel with four screw holes—this is the drive bay cover.
• Use your Phillips-head screwdriver to remove all four screws.
• Set the screws aside in a small container so you don’t lose them.

Be gentle when removing the cover. It should lift off easily once the screws are out.

Step 3: Prepare the Hard Drive

Now it’s time to install the drive into the bay.

• Remove the hard drive from its packaging.
• Check that it’s a 3.5-inch SATA drive with standard mounting holes on the sides.
• Align the drive so the SATA connector faces toward the back of the HomeBase 3 (where the ports are).

The drive should slide into the bay smoothly. Don’t force it—if it doesn’t fit, double-check the orientation.

Step 4: Secure the Hard Drive

Once the drive is in place, you’ll need to secure it with screws.

• Use the four screws that came with the drive (or the ones from the original drive, if replacing).
• Screw them into the side mounting holes on the drive and bay.
• Tighten them firmly, but don’t over-tighten—this can strip the threads.

Most surveillance drives come with mounting screws. If yours didn’t, check the box or contact the manufacturer. Using the wrong screws can damage the drive.

Step 5: Reattach the Drive Bay Cover

With the drive securely installed, it’s time to close up the device.

• Place the cover back over the drive bay.
• Align the screw holes and reinsert the four screws.
• Tighten them evenly to ensure a snug fit.

Make sure the cover is flush with the bottom of the device. A loose cover could cause vibration or noise during operation.

Step 6: Power On the HomeBase 3

Now that everything is reassembled, reconnect the power.

• Plug the power adapter back into the wall.
• Wait for the HomeBase 3 to boot up—this may take 1–2 minutes.
• Watch for the status light: it should turn solid blue when ready.

If the light flashes red or doesn’t turn on, double-check your connections and ensure the drive is properly seated.

Formatting the Hard Drive via the Eufy App

Installing the drive physically is only half the job. Now you need to format it so the HomeBase 3 can use it for storage.

Open the Eufy Security App

Make sure your phone or tablet is connected to the same Wi-Fi network as the HomeBase 3.

• Launch the Eufy Security app.
• Log in to your account if prompted.
• Tap on the HomeBase 3 device from the home screen.

Access Storage Settings

Once you’re in the device menu, look for storage options.

• Tap on “Device Settings” or the gear icon.
• Scroll down and select “Storage” or “Hard Drive.”
• You should see a message like “New hard drive detected. Format now?”

If the drive isn’t detected, try restarting the HomeBase 3 and checking the app again.

Format the Drive

Formatting will erase any existing data on the drive, so make sure it’s blank or you’ve backed up anything important.

• Tap “Format” to begin the process.
• Confirm your choice when prompted.
• Wait for the formatting to complete—this can take 10–30 minutes depending on drive size.

During formatting, the app may show a progress bar. Do not disconnect power or close the app during this time.

Once done, you’ll see a confirmation message and the new storage capacity displayed.

Enable 24/7 Recording

With the drive installed and formatted, you can now set up continuous recording.

Go to Camera Settings

• In the Eufy app, select one of your connected cameras.
• Tap “Device Settings” and then “Recording Settings.”

Choose Recording Mode

• Select “Continuous” or “24/7 Recording.”
• Adjust video quality if needed (higher quality uses more storage).
• Repeat for each camera you want to record continuously.

You can also set motion detection zones and sensitivity to reduce false alerts, but continuous recording will capture everything.

Check Storage Usage

To monitor how much space you’re using:

• Go back to the HomeBase 3 storage settings.
• View the used and available space.
• The app may also show estimated recording duration.

If storage fills up, older footage will be automatically overwritten in a loop.

Troubleshooting Common Issues

Even with careful installation, you might run into problems. Here’s how to fix the most common ones.

Drive Not Detected

If the HomeBase 3 doesn’t recognize the new drive:

• Power cycle the device: unplug it for 30 seconds, then plug it back in.
• Check that the drive is properly seated and screws are tight.
• Try a different compatible drive to rule out hardware failure.
• Ensure the drive is not pre-formatted with a file system like NTFS or exFAT.

Formatting Fails or Stalls

If formatting gets stuck or fails:

• Restart the HomeBase 3 and try again.
• Use a smaller drive (e.g., 2TB) to test if the issue is capacity-related.
• Contact Eufy support if the problem persists.

Unusual Noise or Vibration

Hard drives can make noise, but excessive clicking or grinding is a bad sign.

• Power off immediately and check the drive mounting.
• Ensure screws are not over-tightened.
• If noise continues, the drive may be defective—replace it under warranty.

Recording Stops or Skips

If footage is missing or playback is choppy:

• Check available storage—low space can cause recording issues.
