USB flash drive can be in various brands
and types. A 32GB USB flash drive can store a lot of data, so it will be a terrible
disaster if a 32GB flash drive changes its file system to RAW. A RAW drive
often means an unformatted drive, so Windows may ask you to format the USB
drive when it shows RAW. If you don’t want to lose any data from the USB flash
drive, you need a powerful and reliable USB drive recovery program before you
format it.
