Hi Liam,

This problem can be caused by partition issues on your external drive, using the wrong file system, dead USB ports, driver issues in Windows, or other problems.

Follow the below steps to resolve this issue:

Step 1
First, let’s check whether Windows detects the drive when you plug it in. Plug your removable drive into your computer. If it’s an external hard drive, you may have to flip a power switch on the hard drive to activate it.
Next, open the Disk Management tool. To do so, press Windows Key+R, type diskmgmt.msc into the Run dialog, and press Enter.

You should see your external drive listed in the Disk Management window. Even if it doesn’t appear in your Computer window because it doesn’t contain any partitions, it should show up here.


If you do not see the drive here, then follow next step:

Step 2:
Look under Disk drives and check for any devices with a yellow exclamation mark next to them. If you see a yellow exclamation mark, you have a driver problem. Right-click the device with a yellow exclamation mark, select Properties, and look at the error message.


Open its Properties and update its driver, if an update is found to be available.


If it doesn't help, follow next step.
Step 3:
Run the Hardware and Device Troubleshooter or the Windows USB Troubleshooter and check if it helps. The automated tools check the hardware or USB connected to the computer for any known issues and fix them automatically.

This should resolve your issue.

Regards,
Lokesh.
