Thanks for the tip, I will give it a try!

Is there a way to turn off the caching on writes to external usb devices so that I can unmount them the instant a transfer is completed?

But be aware, that it will really slow down working with your usb-stick (?). Just add this option to your fstab or the used hotplug-script. Cu Sebastian </pre> </blockquote> </body> </html>
