Part 2. How to Recover Files from USB Drive Not Formatted Error
Why You Need A File Recovery?
Most of the people have the concept in their minds that once format the USB driver, the files in your driver will permanently disappear. Actually, it is not. Let me explain the theory about how the driver works when it gets a command about deleting or formatting.
When deleting your files, the system will not actually erase the files, it just adds a sign on the files that the files need to be deleted. Files will only be deleted when new files are written in the same place; Comes to formatting, there is a catalog in the driver which is used to find your files or anything you put in the USB driver. When you format the USB driver, the system just adds a “deleted sign” on all of the files or just erase the catalog. You will be unable to find your files without the “catalog”, but you still can recover almost everything in your USB driver if you stop writing anything to it.
