OK, well that's a kernel warning; doesn't look like too much to be worried about.

Well that looks like a bad sector read - either the drive or the floppy; if you're getting the same values in multiple drives then probably the floppy. I'm not convinced any 1.44MB floppies manage to survive more than 1 or 2 reads (if you're lucky....). So from that error you're at head 1 on cylinder 18, and with 18 sectors/track we get to sector 666 (!!) + 14 -> 680 - which is close enough to the 679 reported for me think that's about right. Not quite sure where the 84 comes from - 4KB blocks?
Anyway, sounds like duff disk.

Same warning as above.
