My main point is that the standard of manufacture has (in most cases) improved considerably over the last two or three 5-year periods. Floppy disks used to be rated for 5 years storage if used lightly enough not to wear the magnetic surface clean away. Today's floppies are rated at ten years reliable storage and it is possible to get Teflon-coated disks which reduce the problem with the surface wearing out. Newer models of drives are mostly improvements over previous models. Manufacturing techniques, materials and knowledge have definitely improved. You make a valid statement and so do I. Just take a (little-used) drive from ten years back and a modern one. If you find no significant difference I'd be inclined to say that the so-called modern drive was old stock. Who trusts valuable data to magnetic media anyway? :-) -- Adam David. (adamd@rhi.hi.is)
