mount & umount read-only floppy: unmount failed: Input/output error ??

[Rob]

That's strange - I get errors as soon as I try and do this, before the
filesystem is even available.

Perhaps the updates from mounting the floppy aren't being written out to
the actual media until you try to unmount it - some kind of caching
issue?

What happens if you try to touch a file on the (incorrectly) writeable
floppy?
