I know this has little connection to today's situation, but IBM have in the past had disks that could be doubled in size by a "firmware" upgrade.
My dad has worked on computers since the late 1950s and he remembers the IBM technician turning up to upgrade a "disk pack". Apparently he opened the disk pack, took some wire cutters from his toolkit and snipped a single wire. Instant 100% upgrade in disk space...
