Pen Drive, USB, or Flash Drives call it whatever (though these terms are used interchangeably they refer to slightly different technologies), at the end of the day, all that matters is that they are extremely portable and allow us to hoard data.
Though it works just fine for the large part of its lifetime, chances are it'd go corrupt sometimes. Yes, we are talking about the USB Flash Drive detected but not showing in My Computer issue.
And when they stop working or go corrupt we simply assume that it can't be fixed and dump them. What we don't know is that it takes just a few clicks (simple troubleshooting) to make it function as it'd otherwise.
So, without wasting any time, let us tell you how to quickly make your flash drive work properly.
Cross check if it's working on other ports
We'll anyway, tell you how to fix the problem, but, we'd recommend you to plug in the pen drive in alternate ports to cross check. If all fail, proceed to next step.
Change the Removable Drive Letter
If you are unable to see the Removable Drive option in My Computer, all you have to do is rename the Drive letter allocated to it earlier.
To do this, follow the below steps.
Step 1: Open Control Panel > Administrative Tools > Computer Management
Step 2: When you open the Computer Management page, you'll see three options (towards the left side of the screen) - System Tools, Storage, and Services and Applications. Click on Storage > Disk Management.
Step 3: Next, right click on the pen drive and select Change Driver Letter and Paths.
Step 4: If there's already a letter allocated to your drive, change it, if not allocate a letter to it.
Step 5: You should be able to see your drive in My Computer if you've followed all the above steps. In case if it's still not visible, restart your computer and you're done.
