I agree. But this is what makes no sense. I can loop writing a 1 M file to the usbdrive. The system will run out of memory after 6-7 loops. But if I umount the usbdrive between each write the system works fine. I don't see how performing an umount would have any affect memory management within the HCD. Any ideas?
