Sounds like the disks themselves could be bad, if the floppy drives in
question are operating fine.

What brand of disks are they?

In my experience recently, I've found that floppy disks manufactured today
have a much higher failure rate than old floppy disks - I think very little
attention is paid to quality, and very few buyers of floppy disks must care
enough to complain.  (Back in the 1980s, floppy disks were expensive and all
the good brands had lifetime warranties.)

All Macs will do a verification pass on a formatted floppy, to make sure
it's a good floppy.  Older versions of the OS would fail the format if there
was even one bad sector found.  Later versions (perhaps starting with OS 8?)
would start to lock out bad sectors in a second verification pass, and as
long as the number of bad sectors didn't exceed a certain threshold, you
could still use the disk, however the total usable capacity would be reduced
by the number of bad sectors locked out (and if there were too many bad
sectors, it could still fail to format).

So I'd say you either have bad floppy drives, or more likely, bad floppy
disks.
