USB Drive Not Showing Up In Explorer
How To Fix A USB Drive Using Diskpart
Now you need to list the disks available to you:
This will bring up a list of disks. You now need to select the one that goes with your USB drive. To identify it look at the size of the disk. It will be the same as the disk listed in the Disk Management tool.
Type the following to select the disk:
select disk 1
(Replace disk 1 with the number of the disk for your USB drive, i.e. select disk 1, select disk 2, etc).
Now you need to list all of the partitions on the USB drive.
list partitionIn my case there was only 1 partition but you may have more than one partition. For each partition that you see listed type the following 2 commands:
select partition 1
delete partitionReplace partition 1 with the name of the partition listed in list partition. After following the commands run the list partition again to see the partition numbers.
When there are no more partitions you can stop.
Finally you need to create 1 more new partition. To do this type the following:
create partition primaryYour USB drive now has a single primary partition again.
Formatting Your USB Drive
As you can disk 1 now shows 7.45 gigabytes but it is a RAW partition and not really usable in this state. Right click on the disk 1 and choose format.
You can now give the USB drive a label and choose a file system. I recommend FAT32 for a USB drive as it is the most supported file system across multiple architectures.
Click "OK" to format the USB drive.
A message will appear stating that you will lose all data on the USB drive. Click "OK" because you already did that when you started deleting partitions.
At this point within Explorer you should be able to see your USB drive. If it doesn't show up, right click on the partition within Disk Management and choose "Change Drive Letter And Paths".
Click on the "Add" button and choose a drive letter to associate with this USB drive.
Your USB drive should now be fixed.
