The external hard drive not showing up issue is one of the most common issues of disk storage. Actually, there are two manifestations to consider: the external hard drive does not show up in Disk Management Windows 10 and is not recognized in Windows 10/8/7.

In this post, you will learn the possible causes as well as the solutions for this issue.

External Hard Drive Not Showing Up in Disk Management #

If your external hard drive is not appearing even in Disk Management, you need to figure out the reason. Usually, you can try the following to identify the issue:

  1. Connect the external hard drive with another USB port.
  2. Connect the external hard drive with another USB cable.
  3. Use another USB drive/external hard drive and connect it to your computer.
  4. Connect the external hard drive to another computer.
  5. Check if the hard drive is detected and enabled in BIOS.

Doing the above helps you make out if your external hard disk has failed or not. If the drive has already failed, you need to use another one.

External Hard Drive(HDD) is Not Detected in This PC #

Most of the time, the external hard drive not showing up means the external hard drive is not detected in This PC. This is more complicated but you can find a way to fix it.

#1. The External Disk Has No Partition

Before you can save data to a hard drive, you need to create partitions on it. Before creating, you need to choose a partition style for that drive. Therefore, check out if the external hard disk does have an MBR/GPT partition table and a partition on it.

If the external hard disk is shown as Basic & Unallocated, this indicates that there is no partition created on it. In this case, you need to right-click on the Unallocated space, choose New Simple Volume, and follow the wizard to create one.

If it is shown as Unknown, Not initialized,  right-click on it and choose Initialize. Then in the pop-up window, choose a suitable MBR partition style. Take care that if your external disk has more than 2TB storage space, choose GPT to make full use of it. Finally, create new partitions on it by following the wizard.

If your situation is different, move on to find other solutions.

#2. The Partition on the Drive Has No Drive Letter

A drive letter is a single alphabetic character starting through A to Z and is assigned to a physical computer drive or drive partition.

Without a drive letter, Windows won’t display it on This PC. Thus, if the external hard drive does not come up in This PC, check out if all partitions on it have a drive letter and assign one to the partition that has no drive letter.

To do this:

Right-click on the partition without a drive letter and choose Change Drive Letter and Path from the context menu. Then click Add and then choose an available drive letter from the drop-down box. Finally, confirm the change.

#3. The Partition on the Drive Has Unsupported File System

To use a partition normally, the drive letter is not the only determinant. You should also check if it has a recognized file system in Windows.

Windows can recognize FAT (12/16/32), exFAT, and NTFS file systems without errors. But if the partition on the external hard disk has a different file system such as Ext (2/3/4) or RAW file system, it will not be showing up normally and refuse access. Therefore, you need to do the formatting.

This is much easy to perform, but before you start, be aware that formatting will definitely lead to data loss. So, please make out if there are some important files saved on the drive. If you do have, external hard drive data recovery should enjoy high priority.

Now it is time to format the external disk. Just select any partition that has an unsupported file system, choose Format, choose NTFS, and then confirm the formatting.

When the format completes, check if the external hard drive is not being displayed Windows 10 issue persists.

#4. The External Hard Drive Has Hidden Partitions

This is much similar to the external disk that has no drive letter but is different fundamentally. Indeed, a hidden partition has no drive letter, but the cause is the hidden partition type ID.

In Windows 10 Disk Management, you only have the option to delete a hidden partition. Therefore, you had better search for reliable disk partition manager software to help you unhide that partition.

#5. The External Hard Drive Has Lost Partitions

This is more difficult, for it involves indispensable partition recovery or data recovery as long as you need the data saved in, which usually costs some money.

Disk Management won’t help in this case, so you need to find a data recovery program to help you recover lost partitions or you need to consume data recovery which takes more time and effort.

#6. The Drivers Are Outdated

To support your disk, Windows offers hard drive drivers and your hard drive manufacturers also release some drivers.  If the driver is outdated or problematic, your external hard drive won’t show up.

So you can try to disable or uninstall the driver and then enable/reinstall. If you are not familiar with the process, use a professional driver tool – IObit Driver Booster to help you fix an external hard drive not recognized Windows 10.

Tip: Having your driver always up-to-date is very useful in dealing with Windows hardware issue. It also works to resolve DNS Server Not Responding error.
