Store your drive in a case or bag when travelling to protect it.

With large media libraries and sensitive documents to store, external hard drives are a laptop accessory you don’t want to forget. Just connect the drive as needed whenever extra storage space is required.

External Hard Drive Not Showing Up

If your external hard drive is not showing up or being detected by Windows, try the following troubleshooting steps:

Check USB cable connections – Unplug and reinsert connections at the drive and PC to ensure a proper connection.

Try a different USB port or cable if possible.
Reboot your computer to reset the USB subsystem.
Ensure the external hard drive has power – If powered via wall outlet, plug it directly into the wall.

Verify the drive shows up in Disk Management – Open Windows Disk Management to see if the drive appears here even if not in File Explorer.
Assign a drive letter if needed in Disk Management.
Check if the drive shows up in Device Manager – Here you can check for hardware errors or driver issues.

Update USB and chipset drivers if available.
Disable USB selective suspend in Power Options if the drive keeps disconnecting.
Enable USB debugging in Developer Options if using Android.

If the external drive still won’t show up, it may be physically damaged and need replaced. But try the above steps first to resolve most detection issues.

Formatting an External Hard Drive

When you first connect an external hard drive to Windows, you may be prompted to format it. Formatting erases any prior data and partitions on the drive and prepares it for use with your PC.

Follow these steps to format your new external hard drive in Windows:

Open Windows File Explorer and right-click on the new external drive listing.
Select “Format” from the menu.
Choose your desired file system – This will be NTFS for most users. Leave allocation size default.

Give the drive a descriptive name if desired, such as “External USB”.
Check “Quick Format” to skip scanning for bad sectors.
Click “Start” to begin formatting.

The formatting process may take several minutes to complete depending on the drive size. Once done, the drive will be ready for use.

Optionally, you can format an external hard drive using these advanced options:

Partition drive before formatting to create separate logical drives.

Run a full format scan rather than quick format for full error checking.
Choose exFAT instead of NTFS for macOS compatibility.
Perform a full wipe of the drive before formatting for security purposes.

But for most users, doing a quick NTFS format will sufficiently prepare a new external drive for use.

What File System to Use for External Hard Drive

You’ll need to choose a file system when formatting your external hard drive. The most common options are:

NTFS – The most modern file system used by Windows. Offers the best performance and supports files over 4GB.

exFAT – Compatible with macOS and Windows. No file size limit but less efficient than NTFS.
FAT32 – Legacy file system compatible with all devices. Limits files to 4GB.

For use solely with Windows, NTFS is recommended. It’s the fastest and most feature-rich choice.

exFAT can be used for external drives that may also connect to a Mac. It has wider compatibility but some efficiency drawbacks.

FAT32 only should be used if you require compatibility with really old devices. It lacks most modern features.

Stick with NTFS for PC-only external drives. Consider exFAT if cross-platform support is needed.

How to Use External Hard Drives

Once formatted and connected to your PC, using an external hard drive is simple:

File Transfers – Copy/paste or drag and drop files to move them on and off the external drive.
File Location – Save new files directly to the external drive. Designate it as a storage location.

Applications – Install apps directly to the external drive. Games, programs, and the OS can run from it.
Backup – Use backup software to schedule regular backups to your external drive.
Extra Space – Store large files like photos, videos, ISO files and other media on the drive.

Basically, you can treat your external hard drive as additional internal storage space. Move files between your local drive and external drive. Install programs and store all types of files. It expands the overall storage capacity of your PC.

Just remember to safely eject the external drive before removing it!

External Hard Drive Care Tips

To maximize the lifespan of your external hard drive:

Safely eject before disconnecting to avoid potential drive errors.
Be sure to disconnect if the drive won’t be used for a while.
Always use the USB or power cable when using for best performance.

Don’t expose to moisture or extremely high or low temperatures.
Keep the drive in a bag or case if travelling to avoid damage.
Periodically scan for viruses if connected to multiple PCs.

Avoid forcefully disconnecting when files are being accessed.

Following these basic care principles will keep your drive working as long as possible!

External Hard Drive vs Cloud Storage

So should you use an external hard drive or cloud storage? Each have pros and cons:

External hard drives:

Provides expansive local storage
No recurring subscription fees
Allows full control and ownership of data

Files can be accessed without an internet connection
Provides data transfer speeds limited only by the drive interface and PC capabilities
Possibility of drive failure or physical damage

Requires physical space to store and cables to connect

Cloud storage:

Access your files from anywhere with an internet connection
Data synchronization across devices

Cloud data is secured, monitored and often backed up
Scalable storage available for reasonable monthly rates
Uploading/downloading files can be slow depending on internet speeds

Recurring subscription costs
Cloud outages can disrupt access
Third party controls security of your data

For most home users, a combination of both solutions is beneficial. Use an external drive for local backups and storage. Maintain vital files in the cloud for omnipresent access and redundancy.

Conclusion

Connecting an external hard drive to desktop or laptop PCs using USB connections is straightforward. After safely ejecting any connected drives, simply plug the USB cable from the external drive into your computer. Most external hard drives are plug and play, with driver software automatically installed by Windows.

Double check that the new external drive appears within File Explorer to confirm the detection was successful. At that point you can move files back and forth, saving data and installing applications externally. Just remember to properly eject before disconnecting.

Maintaining your drive according to manufacturer recommendations will maximize longevity. Choosing the right interface and formatting the drive properly is key as well. For widespread use and backup, it’s hard to beat the flexibility and portability of an external HDD. With terabytes of affordable storage space, they are a wise investment for any PC user needing more capacity.
