Thanks all!

I will keep track of whats going on on the internal SD; I think I can reformat it from OSX as FAT32.

WRT to 'copying' shouldn;t a mv command work fine? I tried it from OS X command line and got a slew of errors with file flags ( weird ). I haven't yet tried the N810 command line mv.

but, I am not in california now, I'm in switzerland and I have maps! thanks to everyone. I even sometimes get a GPS lock: sweet.
