  1. The most likely reason for the error message is that there is a directory called /dev/sdb1 preventing the creation of the device node for accessing that partition.

    I'm guessing that in the past you accidently created this directory as a mount point under /dev. You can check if you have with:

    ls -ld /dev/sdb1

    If the first character is d, you did, and you need to delete or move this directory elsewhere.

    sudo mv /dev/sdb1 /tmp

    If you get the error message:

    mv: cannot move ‘/dev/sdb1’ to ‘/tmp/sdb1’: Device or resource busy

    then something is still mounted there. In which case mount | grep sdb1 to find out what it is, then try again with:

    sudo umount /dev/sdb1
sudo mv /dev/sdb1 /tmp

    It will now be able to create the device file when you next reconnect your flash drive, and should be able to create and format the first partition on that drive.

    This is how i solved my problem:

    1. Format my pendrive
    2. Restart the system (I really don't know what is the basic fundamental behind restarting the system but it helped me.)
    3. It shows Mounted pendrive. so format it again and create a new partition with FAT filesystem - but with this i am not able to create folder.
    4. So format it again and create partition with NTFS filesystem and it worked.
