Is it safe to format the RAW USB flash drive for RAW file system fixing? Technically speaking, you should try to avoid formatting it when there are a lot of files inside. You need to recover data from the raw usb at first and then get it fixed later.
The only way to format a USB flash drive is to connect it to a computer that can recognize it.
Flash drive, namely USB flash drive, pen drive or thumb drive, appeals to many people due to its small size with large capacity.
Since you are now with a raw pen drive, we would like to share some basic computing knowledge with you regarding to the file system on storage media.
NTFS/FAT32: It is set to be ntfs/fat32 when you firstly receive your flash drive from factory, resellers, online stores, or local digital shops and the early state of usb flash drive has been formatted from RAW to ntfs/fat32 by factory.
So it's already good for storing data that you don't have to do anything else about its formatting or file system.
File System RAW: it is the state in factory during producing the flash drive when it is first made inside of factory and then later the factory would operate a low level of formatting to make its file system raw to Windows easily recognized file system: ntfs, fat32, exfat or more.
File System NTFS, exfat, fat32 are Windows acceptable file system for digital storage devices according to different capacity, abilities, time of speed, block size and age of popular settings.
File system hfs is a Mac file system that is acceptable under the MAC OS, ie iOS.
If you did this, I'm afraid the files on the flash drive will be corrupted because of overwriting, and they cannot be recovered by any recovery software. You are strongly suggested that do not input new data on your flash drive after formatting the drive.
Getting into the resolution of these road blocks can lead users in a catastrophic direction in which files and folders will be lost forever.

Not only does the software work with multiple components of all installed hardware on Windows to guide you step-by-step in avoiding disaster; it also offers a comprehensive rescue capability to retrieve lost files due to premature formatting, network failure, loss of power, failed partitions, and much, much more.
