unmount the usb device

I have mounted my USB device by the command
mount -t vfat /dev/sda1 /mnt/usb

When I trying to unmount it by the command
umount /mnt/usb, I have the "device is busy" message.

So, how can I unmount it?

Are all files finished copying and you're not playing any files that are on the device? They may sound like stupid questions but I know I've done that before

If you really can't remove it, shutdown/restart your computer and pull the USB out.

Plus you cant unmount it if your 'cd'ed into a folder on the device.

Really, after I have closed all the terminal windows, the umount works.
Thank you.

Reasons for not being to unmount

Commonly there are 2 reasons why you get the "busy" message that won't let you unmount.

1) You are still somewhere in the mounted file tree (some terminal or program)
2) There is still data in the write cache that has not been written

Solution to one was posted above
For 2) do
It should write the remaining data in the write buffer.
This can take a while, wait until the prompt appears again.

Then try to unmount it.
