Pro Tips to Fix Hard Disk Not Detected on Windows

Here's a list of pro tips on how you can fix your Hard Drive, which is not being detected by your Windows PC.

Tip 1. Try Plugging in the Hard Drive into another USB port

The first way to fix a hard drive not detected on Windows is by trying to plug it in the other USB port. Changing the port of connecting the Hard Disk to the PC can make Hard Drive show up. Here's what you can do.

• Plug out the Hard Drive from the USB Port in which it is currently.
• Now, change the USB port and try reconnecting the drive to your PC.

If this fix works, this means that the problem is with your system's USB port and not with the Hard Disk.

Tip 2. Try Connecting the External Hard Drive to Another Computer

If changing the USB port does not work to fix External Hard Drive not detected on the Windows issue, then try connecting the Hard Drive to another PC. For this, you simply need to switch and try connecting the external hard drive to another PC.

You can now check if External Hard Drive is being detected by another PC. If yes, then there was some issue with the previous PC and if the issue is still not resolved, then move on to the next method.

Tip 3. Create a New Volume to the Unallocated Partition

In case you see that your Hard Disk is simply unallocated in the Disk Management, then you just need to create a new partition for it. Here's a quick guide on how you can do it in simple steps:

• Right-click on the unallocated disk and select "New Simple Volume" from the list of options.
• Now, a "New Simple Volume Wizard" will show up. You just need to follow the wizard to specify the volume size and assign a path or drive letter.
• Once completed, remove the external Hard Disk and connect it to your Windows PC again.

Now, you will find that your Hard Drive is detected and showing up in Windows File Explorer.

Tip 4. Update Disk Drivers

• Firstly, tap on the "Start" button, type "Device Manager," and hit the "Enter" key on your keyboard.
• Here, choose the "Device Manager" option, expand categories to find the name of your External Hard Drive, and simply right-click on it.

• Now, choose "Update Driver" from the drop-down list and select the "Search automatically for updated driver software" option.

  

That's all! You have successfully updated the Disk Drivers.

Tip 5. Assign a Drive Letter

If none of the above-stated methods worked to fix your Hard Drive issue, then try fixing it by changing or assigning a drive letter. If the External Hard Drive does not have a drive letter or if the existing drive letter conflicts with the other disks, then your Hard Drive will not show up on the PC.

• Right-click on your hard drive and choose the "Change Drive Letter and Paths" option.
• Next, select the "Add" option if your Hard Drive does not have a drive letter or select the "Change" if your Hard Drive already has a drive letter and you wish to change it.

You can now check if the issue is resolved! In case it still persists, switch to the next method.

Tip 6. Format Hard Drive

Sometimes the unsupported File System can cause your Hard Drive not being detected by the PC, and here formatting the Hard Drive might help you. In case your Hard Drive is partitioned but still not detectable by the PC, then there are chances that your Hard Drive is partitioned with a different File System.

So, in order to fix it, you will need to reformat the External Hard Drive with NTFS File System or FAT32 File System, whichever is supported by your Windows PC. For this, you need to:

• Go to "Disk Management" and right-click on the Hard Drive.
• Here, choose the "Format" option.

• Next, select "NTFS" or "FAT32" from the File System, and that's all.
