I don't understand why that would be true (althoug it may be). I can
write to a raw tape just fine with tar. I can do the same thing and
tar directly to a floppy, no filesystem or special utilities needed
(not that tar is not very special to me). Why can't I do the
same with a hard drive? Plus, I've seen more than one mention of
people using 'dd' to clone disks (not _that_ scares _me_).

If it is true that it does not work for a hard drive, what is the
fundamental difference between writing a tar archive to a raw tape,
a raw floppy disk, or a raw hard disk?
