repair external hard drive

Thanks to plug and play technology, connecting an external hard drive to your computer is now quite simple and straightforward. All you have to do is plug it in, wait a couple of seconds and it should be detected and displayed in File Explorer. Unfortunately, sometimes it doesn't show it and this can be worrying. In these cases, you need to know what to do, otherwise you risk not being able to access the important files on your hard disk. If this is your problem, in this guide we will see how to repair external hard drive that is not detected by the Windows computer.

Repair external hard drive

However, in this guide we have provided several steps which will hopefully help you resolve any issues related to the external hard drive that is not detected or displayed.

Check the cables and ports

The simplest thing you can do is make sure cables and ports are working properly. If you connect an external hard drive and it is not detected, one of the reasons may be a defective cable or a damaged port. This can be easily resolved by replacing the cable with another and seeing if the problem persists.

You can also control the port by connecting another device, such as a keyboard, mouse, microphone or webcam, and see if your computer can detect it. If it detects it, then you know that the doors work well and that perhaps you need to go to the next step.

Also, if you're using a hub (which is quite a popular accessory these days), try disconnecting the hub and connecting the external hard drive directly to your computer's USB port. This is due to the fact that the hubs manage multiple and peripheral connections, some cheaper models may have compatibility problems or poor power management, and may not be able to provide enough energy to power the unit, thus preventing it from being detected.

Checking the external hard drive on another computer

If there is a reason why SSDs are gaining popularity, due to the fact that they do not contain moving parts. This differs from more traditional HDDs that still use rotating discs. Over time, wear can cause the unit to stop working, which means that the unit not detected is not a software problem but a hardware problem.

If you have access to another computer, try connecting the external hard drive to that computer to see if it can be detected. If so, it means that there may be some software problems on the first computer. If it is still not detected, then there is the possibility that perhaps, only perhaps, the hard drive itself may have some problems, including the drive itself or the controller is broken.

Switch to a supported file system

Due to the presence of multiple operating systems such as Windows, Mac and Linux, there are times when the drive may be formatted in such a way as to only support the file system of a platform. For Windows users, supported file systems include NTFS, FAT32, exFAT or ReFS.

In order for a Mac-formatted external hard drive to work on Windows, you will need to format it on a supported file system. Unfortunately, this process usually involves cleaning the drive completely, so the best way to do this is to format it at the beginning before you start putting content on it. In addition, formatting it in a file system that supports multiple platforms simplifies life even if you switch from Windows to Mac (see our guide here on how to write NTFS disks on Mac or how to open external hard disk not recognized by Mac).
