Well, a stupid one: I sometimes use my Sharp Zaurus for writing my phlog posts
when I'm not in front of the desktop. Then I pull the SD card from the Zaurus
and put it (in an adapter) to the USB port ot the NSLU-2. That's easy and
straightforward. Then I move it back. But today I found that the card is
mounted read-only in the Zaurus. I tried to remove it and put back, then
remount it via the GUI and remount it with use of the 'umount' command and
nothing worked. The problem was, of course, in the position of the read-only
switch on the card: I touched it during manipulation... It's a full size SD
card, so it has such switch (the most time I use microSD ones which do not have
these things - so I absolutely forgot so that thing exists).
