USB RAW format

Is it possible to repair raw file system on usb disk drive when it was changed from ntfs to raw format?

I have a Samsung external usb that has recently changed to file system raw. The chkdsk seemed did not work either since it reported chkdsk was not available for raw drives... Is there free repair tool that could do the magic to the raw usb, I mean some tool to do the raw repair?

The format of usb file system is supposed to be something among ntfs, ntfs5, fat32, exfat, hfs... and ntfs would be the most often used file system for usb disk or flash drives.

Why usb is raw and asking for a formatting?

This could be the file system error, master file table error, bad sectors and other unknown causes that made the usb device to be raw format. When Windows could not know what the format of your pendrive, it would pop up a warning: hey, you need to format the disk before you can use it. That's what we see on the above photo.
