Connecting and using an external hard drive

An external hard drive is an essential tool for anyone with a lot of files. Whether you want to store photos, back up important documents, or simply need more storage space, an external hard drive has you covered. In this article we explain step by step how to connect an external hard drive and get the most out of it.

What is an external hard drive?

An external hard drive is a storage device that you connect to your computer with a cable. Unlike the internal hard drive inside your computer, you can easily take an external drive with you and use it on different computers. External hard drives come in various sizes, from compact portable models to larger desktop versions with more storage capacity.

Benefits of an external hard drive

Using an external hard drive has several benefits. First, you get extra storage space without having to change anything about your computer. It is also ideal for backing up important files. If something happens to your computer, your files are kept safe on the external drive. On top of that, you can take the drive with you to exchange files between different computers.

Choosing the right external hard drive

Before you buy an external hard drive, it is important to decide what you want to use it for. There are several things to consider when making your choice.

Storage capacity

External hard drives are available in various storage capacities, ranging from 500 GB to several terabytes (TB). For storing documents and photos, 1 TB is often more than enough. If you have a lot of videos or want to make extensive backups, 2 TB or more is recommended.

Connection type

Most modern external hard drives use a USB connection. Check which type of USB port your computer has. USB 3.0 and USB 3.1 are faster than the older USB 2.0. Some newer drives have a USB-C connection, which is becoming increasingly common on modern laptops.

HDD versus SSD

There are two types of external drives: HDD (traditional hard disk drive) and SSD (solid state drive). An SSD is faster and less sensitive to shocks, but also more expensive. An HDD offers more storage space for less money, but is a bit slower.

Connecting an external hard drive: step by step

Fortunately, connecting an external hard drive is very easy. Follow the steps below to get started right away.

Step 1: Unpack the drive

Carefully take the external hard drive out of its packaging. Check that all parts are included, such as the USB cable and, for larger desktop models, a power adapter.

Step 2: Connect the cable

Connect the USB cable to the external hard drive. Make sure you plug the cable in the right way; never force a connection. Most cables only fit one way.

Step 3: Connect to the computer

Plug the other end of the USB cable into a free USB port on your computer. For the best performance, preferably use a USB 3.0 port, which you can often recognize by the blue color inside.

Step 4: Wait for it to be recognized

After you connect the drive, your computer will recognize the device automatically. This can take a few seconds. In Windows, a notification usually appears saying a new device has been detected. On a Mac, the drive icon appears on the desktop.

Step 5: Open the drive

Once the drive has been recognized, you can open it through File Explorer in Windows or Finder on a Mac. The external drive appears as a separate drive with its own letter (for example E: or F:) in Windows, or as an icon in Finder on a Mac.

Transferring files to your external hard drive

Now that your external hard drive is connected, you can start transferring files.

Copying files

Open File Explorer or Finder and navigate to the files you want to transfer. Select the files or folders you want by clicking them. Then right-click and choose Copy. Go to the external hard drive, right-click and choose Paste. The files are now copied to the external drive.

Moving files

Do you want to move files instead of copying them, so they are no longer on your computer? Then choose Cut instead of Copy. Note: always check that the files were transferred correctly before you delete the originals.

Drag and drop

An even easier method is to drag files. Open two windows side by side: one with your files and one with the external drive. Simply drag the files from one window to the other.

Safely removing an external hard drive

It is important to remove your external hard drive the right way. Never just pull the cable out of the computer while files are still being transferred, because this can lead to corrupted files or even damage to the drive.

Safely removing in Windows

Click the Safely Remove Hardware icon in the taskbar, at the bottom right near the clock. It looks like a USB plug with a check mark. Click the name of your external hard drive and wait until Windows tells you it is safe to remove the device.

Safely removing on a Mac

On a Mac, right-click the external drive icon on the desktop. Then choose Eject or drag the icon to the Trash. Wait until the icon disappears before you disconnect the cable.

Tips for getting the most out of it

Here are some handy tips to get the most out of your external hard drive.

Make regular backups

Schedule fixed times to make backups, for example weekly or monthly. That way you can be sure your important files are always stored safely.

Organize your files

Create clear folders on your external drive. Use logical names such as Photos 2024, Work Documents or Music. This makes it much easier to find files later.

Store the drive safely

Keep your external hard drive in a dry, cool place. Avoid extreme temperatures and protect the drive from bumps and drops. A protective case can help with this.

Check the drive's health

Modern external hard drives often come with software to check the health of the drive. Use it regularly to spot problems early.

Frequently asked questions

Can I use an external hard drive on multiple computers?

Yes, you certainly can. An external hard drive is not tied to one computer. You can disconnect the drive from one computer and connect it to another. Just make sure you always safely remove the drive before you disconnect the cable. Most external hard drives work on both Windows and Mac, although you sometimes need to format the drive for the file system you want first.

How long does an external hard drive last?

The lifespan of an external hard drive depends on the type and how you use it. A traditional HDD lasts three to five years on average with normal use. An SSD can last longer because it has no moving parts. To extend the lifespan, handle the drive carefully and prevent overheating. Also always keep multiple backups of very important files.

Why doesn't my computer recognize the external hard drive?

If your computer does not recognize the drive, first try a different USB port. Sometimes a port is faulty or does not supply enough power. Also check that the USB cable is properly connected at both ends. Larger external drives may need a separate power supply. If the problem persists, try the drive on another computer to check whether the drive itself still works.

Do I need to format a new external hard drive first?

Most new external hard drives are already formatted and ready to use. You can connect them and use them right away. However, if you want to use a specific file system, for example exFAT for use on both Windows and Mac, you can reformat the drive. Note: formatting erases all data on the drive, so only do this with a new drive or make a backup first.
