I'll bet if you put it in a Win 7 PC and do the error-check it will
un-write-protect it. You may need an adapter SD to USB if your PC does

I have to do this for a particular brand SanDisk flash drive once in a
while.

How can I undo this? "Properties" shows no "security" tab at all for
setting permissions.
