It seems that after I copy a file to my 770 via USB, I have to reboot the 770 to see the file. Anyone else see this?

I use my Linux laptop, running Kubuntu and KDE 3.5, to copy a file. When I unplug the USB cable, the 770 says Memory Card Detected, mounts it, but the file I just copied is not there. If I plug the USB cable back in, I can see the file from my laptop.

Anyone have any ideas as to what would be causing this?

I have repartitioned the card into a vfat and swap partition, if that makes any difference, but I have not seen anyone else mention this phenomenon.
