Hi okay,
You can follow below mentioned steps:
Enable and Format the Drive in Disk Management
If your drive is powered on but still isn’t appearing in File Explorer, it’s time to do some digging.
Open the Start menu and type “disk management,” and press Enter when the Create and Format Hard Disk Partitions option appears. Once Disk Management loads, scroll down to see if your disk appears in the list. If it does, make sure it’s online and formatted. If it’s offline, right-click the disk’s name (e.g. “Disk 2”) and choose Online.
If the disk hasn’t been formatted (it’ll say “Unallocated” under a black bar), right-click it and choose New Simple Volume. This will also solve the problem if the drive is formatted for another operating system, as described above. Be warned that formatting it will erase any data on the drive, so only continue if you’re sure you don’t need anything from it.
Finally, if your drive is online and formatted, but doesn’t show a drive letter next to its name, right-click the volume and choose Change Drive Letter and Paths to add a drive letter. If you’re lucky, one of these simple steps should get your new drive up and running.
Clean the Disk and Start From Scratch
In some more specific cases, the drive will appear in Disk Management, but merely formatting the drive won’t work. This is extremely common with SD cards formatted with Linux distributions for the Raspberry Pi, for example.
To regain your drive’s full capacity, you’ll need to run Windows’ “clean” command, which will return the drive to a completely unformatted state. Again, this will erase anything on it, so only continue if you have no other options—and make extra sure you’re cleaning the correct disk, or you could lose a lot of data.
Open the Start menu, type “diskpart,” and press Enter to open the run command. When the prompt appears, type “list disk” and press Enter to see the disks plugged into your system. If you see the drive in question appear—pay close attention to its size—make a note of its name. We’ll use “Disk 2” in this example.
Type “select disk 2” and press Enter to select the disk you want to clean. Finally, type “clean” and press Enter. This will erase the disk, at which point you can follow the above steps to format it from the Disk Management console.
