Why is my hard drive not showing up on my computer?

There are several reasons that your hard drive might not be showing up on your computer. It could be due to hardware compatibility issues with the device or its drivers. Many times, the problem is due to malicious software that has found its way onto the drive. Your drive might not be accessible because of something you inadvertently did to it. You need to get it operational if you want to recover its data.

Why is my hard drive not showing up on my computer

Being unable to recover data from a hard disk which is not detecting properly poses a problem. Obviously, before you can perform any type of data recovery, you need to be able to access the device. If the drive remains undetected, you won’t be able to do anything with it. We are going to look at why your drive might not be recognized and discuss a valuable data recovery tool to use once you regain access to its contents.

Part 1: Reasons Why Your Hard Drive Is Not Detecting Properly

Here are some of the most common reasons why your hard drive might not be recognized by Windows.

#1. Human error

Your drive might not be detected because of simple human error. This might be due to plugging the drive into a faulty port. In that case, you can try a different interface or computer. More likely, you have deleted or formatted a partition. You might have tried to assign a drive letter and used a value that the operating system cannot use properly. All of these issues will cause any hard drive, including an external Seagate or Western Digital (WD), to be undetected by your OS. The good news is that most of these issues can be resolved fairly easily. More on that later.

Solution:
Drives that do not appear in My Computer or Windows Disk Management are often not formatted or have an incorrect drive letter assigned. Both of these issues can be resolved from within Disk Management where you can format and rename the drive. You can also check Device Manager to make sure that the drive is online.

Alternative solution:
Alternatively, the drive might not be recognized due to device driver incompatibility. Make sure that you have installed the correct driver for your external drive. If the driver has been installed, try removing and reinstalling it. This will often resolve the issue and let you get back to using the drive with no issues.

#2. Viruses and Malware

Infection by a virus or malware program can cause all sorts of problems, including making it impossible to recover files from external hard drive that’s not detected properly. A virus can randomly delete files or format a partition without your knowledge, making the hard drive display as RAW. Malware might change the drive letter or have deleted or corrupted the necessary device driver. In some cases, the damage caused by malware may be the reason your computer won’t boot from the drive.

Solution:
Whenever your hard drive becomes infected with a virus or other malware, you should start by running a virus scan and removing the infection. As a Windows user, you already have a capable antivirus installed on your computer, and its name is Windows defender. You can access it from Windows Security > Virus & threat protection. There, go to Scan options, select Full scan, and click the Scan now button.

Alternative solution:
A drive that has crashed may have experienced a file system error that caused Windows to view it as a RAW disk. The OS will not be able to access the data that was on the drive without being repaired. You can try to repair the partition table and boot sectorData recovery software can recover data from a RAW drive and allow you to reformat the drive after your information is saved to another location.

#3. Environmental Factors

Too much heat or moisture will cause damage to your hard drive and might be a reason that your OS is having trouble detecting it. Of course, it’s then impossible to recover data from a hard disk that is not detecting as it should. While you can obtain some hard drives that can withstand harsh conditions, keep in mind that most drives are meant to be kept cool and dry.

Solution:
Unfortunately, there’s not much you can do to recover files from an external or internal hard drive that’s not detected properly because it’s been exposed to water, dust, or extreme temperatures. Your best bet is to send the hard drive to data recovery professionals and let them attempt to repair it using their specialized equipment.

Alternative solution:
You can avoid sending your hard drive to data recovery professionals if you have a local or cloud backup to recover from. If you do, and the backup is up to date, you can simply restore your lost files to a safe location. Just make sure that the original cause of data loss has been fully eliminated because you don’t want to recover files from an external hard drive that’s not detected properly again.
