I've got a USB stick here that has a blinkenlight as soon as it's powered on (plugged in), even if there is no reading / writing / mounting activity. After you've successfully performed umount, the USB stick _is_ synced and can safely be removed, no matter what you assume the funny lights want to tell you. Maybe that's just a "modern feature" to make the USB stick "more entertaining". :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
