How to restore USB drive after making it bootable?

USB drives have replaced CDs and DVDs to become the default choice for bootable media to install OSs because of the obvious advantages they offer over its predecessors. USBs are easier to work with, faster, more reliable and overall less of a headache.

However, once you’ve installed that super cool OS on your system, what are you going to do with that USB drive of yours? Now sure you could just keep it in case you need to make multiple installs or as a bootable drive for the future, but what if you want to restore it for everyday use?

The first thing that comes to mind is formatting, right? Well, that would work, but, it wouldn’t give you back the whole drive. You’ll get a partition of the drive back, that too the one your current OS can detect. These partitions can be anywhere between KBs to a couple of hundred MBs.

Does that mean your perfectly fine 16GB flash drive is of no use? Well, not really.

Step 6: Go and format the drive as you would from the file manager, and you’ll have your drive back.

Keep in mind though that as a flash drive goes through this cycle over and over again, it tends to lose out on data transfer speed and reliability.
