I tried to copy the original Cisco flash 128MB device to disk on two different WinXP Pro machines with both a Belkin and a Sony Flash reader/writer but
the process fails uniformly with a "blue screen freeze." The fault lies with fastfat.sys according to the blue screen message. Any ideas as to
a successful way to copy the original flash device to disk? Then I will want to copy it back to a Sandisk 2GB compact flash II device so the
"insufficient memory" issue is fixed when I try to upgrade firmware on the UC520.
