Although very useful, USB drives frequently cause various issues like formatting errors or data loss. Programs like Flash Memory Toolkit where designed to help you solve these problems.
This application will offer you a comprehensive set of utilities that help you scan your flash drives for errors, recover lost documents, back up and restore files whenever you like, erase content and more.
You will also be able to format your flash drives and prepare your device for its initial use. All data within your USB drive will be permanently removed, so I advise you to be careful before proceeding with this task.
The downfall of this program is that it takes a while to scan for errors, recover files and back up the drive. Also, the Pause and Resume buttons were missing so all I could do was to wait for the results in order to begin another assignment.
My guess is that, even though it has many useful tools to offer, you can find more advanced applications that can help you perform these tasks a lot faster. This program may not be the best solution that you will ever find but, at least, it's reasonably affordable.
