Detailed Description

One overwritten sector of the otherwise-synthesized FAT16 volume.

A writable host (usb_host_file_ops) creates a file: ra8_fs rewrites a few FAT / root / data sectors. We keep those writes in a small overlay so the read-back reads them back; everything else is still synthesized on the fly.
