A method to convert a plurality of sectors from a first sector format to a second sector format is disclosed. The method provides (N) contiguous first sectors to a sector format conversion device, where those (N) first sectors include a beginning first sector and a first number of bytes, and determines that (M) contiguous second sectors comprise at least the first number of bytes, where those (M) contiguous sectors include a beginning second sector and an ending second sector. The method overlays the beginning first sector onto the beginning second sector, and overlays the (i)th first sector onto part or all of the (j)th second sector. The method then transmits the newly-formed (j)th second sector to a data storage device, and writes that (j)th second sector to an information storage medium.
