Could your problem be that you have the ops backwards? I don't know
about tar+tape but tar+file is
tar -cvf out.tar file
Also, the 'f' is for file output so you are trying to output to a file
named home which can't be done because that's already a directory, and
put /dev/ht0 in it. It blinks because it's being read. How about
tar cv /dev/ht0 /home/
?
