TAR.nlm and Bash and CWD

While attempting to untar a .tar file the file also untar's in the
sys:
volume. I cannot find a way to change my CWD to another volumes or
directory. I have tried this both from the system console and from
Bash. Anyone have an idea of how to get aroung this CWD issue or how
to
redirect output from sys: to vol1:

Thanks,
