Congratulations on solving your floppy problem, but I can understand your problems with floppies. They've gone bad with age for me too. I can read but not write, then I can't read and in most cases can't even reformat.
FreeBSD installation sets structure (base.aa, base.ab, base.ac etc.) suggests that one could install from a big set of floppies, but there's no way I could get such a good set of floppies together. I think my 5.25" floppies and drive hold out better than the 3.5" floppies and drives.
