Why does unplugging USB stick WITHOUT dismount destroys always data?

According to the USB specification I should always be able to unplug an USB stick
from my computers without having arsik to loose data.

But this is not the case.

Whenever I copy something onto my USB stick and plug the USB stick out
then all the just copied data is lost.

Is occurs with different USB sticks and on different computers (under WinXP).

To prevent data loss I always have to dismount the USB stick first (by clicking on
the icon in the Systray).

Is there a way to enable "quick unplug" without having to dismount first?

Maybe there is an option to allow this.

From Explorer:
Properties, hardware, select the USB stick, properties, policies. Make
sure that the check box for "optimize for quick removal" is checked.

You still need to wait for any writes in progress to conclude.
It is highly advisalbe to "safely remove" even with this setting.

It doesn't, if you have write caching disabled and wait for the transfer of
data to finish.
