Although the new USB Flash Drive that you just took out of the bubble pack is already formatted and ready to use, I would suggest you delete the existing partition, and start over.  This is a good idea to protect you from getting a virus.  In the past users have had to cope with companies like Sandisk and their [[U3 Flash Drive Virus]].  They really did intentionally install a virus on all of the flash drives they sold people!  Other times rogue employees have been behind factory new flash media having a virus pre-installed.  If you partition and format your flash drive before use then you know what's on it.{{:Partition_and_Format_a_USB_Flash_Drive_with_Linux}} You can read about Recommend File System for Linux Use on your [[USB Flash Drive]] for some background.  NTFS or FAT32 is recommended due to its compatibility with Windows however if you only plan to use the flash drive on linux systems then you can also use EXT4. You will have to insert the flash drive then make sure it is not mounted, if your system uses automount then you will have to manually unmount the flash drive first. === Partition and Format USB Drive via Terminal ===If your flash drive already has a partition table and you simply wish to reformat the drive then skip to step #3.  In our example we will partition and format a 128GB flash drive attached at sdc. 1.
