Write bytes in a USB disk directly
We all know that USB disk has a flash inside it to store the data but along with the filesystem like FAT/NTFS etc. 
My requirement is to write the data on the flash not enveloped on a file or a file system i.e. data shall be placed in the flash directly without any file/filesystem.
Is it possible , if yes then how.
