Since when could we do this with amigados's filing system, pop things
in and out as much as we want in the middle of amigados doing something.
I don't think so.  Just try doing it with a disk between the time the
light goes out once and then comes on again a few seconds later, and
see what happens, usually "not-a-dos disk".  As for not having redundancy
what good is it if the OS doesn't do anything with it.  No one seems to
be crying over the new FFS doing away with that wonderful rendundancy that
was talked about so much, say in the Byte issue covering the amiga, about
how all the files and their sectors were chained together forwards and
backwards so the entire disk could be rebuilt.  Sure, after awhile we
got DiskDoctor and DiskSalv but the OS as such never tried to fix things
if they went bad, and DiskDoctor sometimes just made things worse, and
we still don't have bad sector remapping.  I don't think the new file system 
is such a bad idea.
