External Hard Drive Not Showing Up PC
Whether you're plugging in a new hard drive or an old one to your computer, it is possible that you can't see it. Some people even reported that the external hard drive is showing up in devices but not in my computer. This is not a rare issue; it has ever happened to many people and will be happening to more.
What are the possible causes for external hard drive not showing up on computer issue?
- Insufficient power supply
- Lack of drive letter
- Outdated drivers
- File system issues
- Partition problems
- Dead USB port
In the following content, I’ll mainly discuss external hard drive not showing up/recognized on Windows 10 in 2 different situations. After that, I’ll tell you what do I do if my hard drive is not detected.
What to Do When You Can't See External Hard Drive
Many people have the same experience – they suddenly find an external hard drive is not recognized by the computer; it won't show up in File Explorer (PC not recognizing external hard drive). The first thing to do at this time is checking whether there’s an AC power adapter and whether it’s plugged in. If not, please plug it into your PC properly.
After that, you should press Windows + E to open the File Explorer and check whether the external drive appears now.
Open Disk Management to Check
If the external or USB hard drive is still not showing up (WD external hard drive or Toshiba hard drive is not showing up in File Explorer), your next step is to open Disk Management and check.
- Open Windows search by pressing Win+S.
- Type disk management.
- Select Create and format hard disk partitions.
- Browse the drives list to look for your external disk.
If you find the external hard disk showing up in Disk Management as unallocated/not initialized/offline, it would be easy to fix the external hard drive not recognized problem (refer to Method 2: Check & Fix the Drive in Disk Management below). This is what people described as external hard disk detected but not showing in My Computer.
Seagate external hard drive not showing up.
I know there are a million posts about this issue, but I haven't come across one that fixed my issue and I really don't want to have to shell out a ton of money recovering my data. Running Windows 10 on an Asus K55N and connecting a Seagate Free Agent Go Flex Desk 2TB external drive. When I connect the drive, it shows in Disk Management and the Safely Remove Hardware icon, but I can't get it to populate in File Explorer. I have not tested on another computer, but I have tested with a different USB cable and was able to connect two other external drives. I did the trial of the Seagate Recovery Suite and was able to see all my files listed, I was just hoping to not have to pay to recover the data (if that's what it boils down to, so be it).- said Corey_23 on Tom’s Hardware Forum

WD external hard drive not recognized Windows 10.
I have a WD My Passport portable USB hard drive which one of my computers can't detect when plugged in. It doesn't show up in My computer, Device Manager or Disk Management. The only way to get the device recognized is to reboot the computer with it connected, enter BIOS (and do nothing), and reboot again. The drive works fine on my other computer. It has the WD Unlocker Software built in.- posted by Lagnaetti on Windows 10 Forums, Drivers and Hardware
Obviously, Lagnaetti finds that his external hard drive is not being detected by My computer, Device Manager or even Disk Management. He wants to know how to fix the external hard disk not detected issue.
As said before, if the WD external drive doesn’t show up on your PC, you should first open Disk Management to have a look. If the WD external disk shows as unallocated/not initialized/offline, you can make it appear easily by formatting, creating a volume, initializing to mbr/gpt, or setting online. However, what if it doesn’t appear?
WD External Hard Drive Not Showing Up in Disk Management
If the WD external hard drive still isn't showing up in Windows Disk Management (computer is not detecting/reading or doesn't see the external hard drive), you should consider making the USB/external disk detected by restarting your computer, enabling legacy USB support, and using a different USB port. It’s possible that the USB port you use is failed so your computer won't recognize the external hard drive. Please try a USB 2.0 port if you're using USB 3.0 and connect the drive directly to the Windows PC instead if you’re using a USB hub.
In fact, there are some cases in which an external hard drive doesn't show up since it has being broken physically. Yet, there are still chances that the unrecognized hard disk can be repaired.
In addition, there are also some people who said their PS4 external hard drive is not recognized or Xbox One external hard drive is not detected/not showing up. I suggest that they connect the external hard drive to the computer and check.
What if the external hard drive still not showing up? When your external hard drive won’t show up on PC, you should first go to check it in Disk Manager. If your computer is still not recognizing external hard drive, you need to try the methods mentioned in this part.
How Do I Get Windows 10 to Recognize My External Hard Drive
External hard drive doesn't show up is a hot topic. Many people said they can't find external hard drive on the computer (computer doesn't find external hard drive). If you also encounter the portable hard drive not showing up (external HDD not showing up) on Windows 10 or other Windows systems, please change a USB port, check in Disk Management, run troubleshooter, update driver, etc.
11 useful solutions you should try:

Is your external drive not showing up? There are many useful workarounds for fixing the external hard drive not being detected in Windows 10 (how to repair hard disk not detected in Windows 7 is basically the same).
Method 1: Turn to Different USB Port or Computer
Change a USB Port
I find my computer doesn’t recognize my external hard drive because the USB port is broken. I tried a different USB port and it worked. If the external HD is not showing up when it's connected via a USB 3.0 port, you can also try a USB 2.0 port to detect the drive. Besides, you should try to connect the external hard drive directly to your PC and see whether your computer can detect the USB drive.
The USB drive not showing up Windows 10 may also occur when the power supply of a USB port is not sufficient. In this case, I advise you not to use USB hubs because some of them are not able to provide enough power supply to the external hard drive.

How to Fix: External Hard Disk Detected But Not Opening
There are also some people saying that their external hard drive could be detected by Windows, but can't be opened. The most direct reason is the file system problem.
When the file system of your hard drive is not supported by Windows, you won’t be able to access the drive. For instance, Windows gives no support for the ext4 file system (designed for Linux) and the HFS + file system (designed for Mac).
After clicking on the drive, you’ll be asked to format the disk before you can use it.
- If you choose Format, you should know that all your data saved here will be lost.
- If you choose Cancel, you will see the message: The volume does not contain a recognized file system.
Actually, the most common causes are:
- The file system is damaged.
- The file system is not supported.
- The drive becomes RAW.
- The parameter is incorrect.
- The file or directory is corrupted and unreadable.
