How to umount partition when someone or something is using it ?? How do i know what proccess or whitch user is using it ?? Is option -f good for this ??
What will happen when some program is writing to /mnt/drive and i'll umount it with -f option. Will it write to /mnt/drive still but in the root drive ??

You can't really unmount directories if they're in use. You need to end or kill the processes using files in those directories. Use the lsof command to find what processes are using a particular file.

fuser is another command that will tell you what's using the drive.

And to kill the process you'd use fuser -k [directory].
