If your tape "was not initialized at all", then possibly it contained
ustar-format junk left over from the last time that it was used, and
yes, that could cause the problem.  ustar format is not compatible
with multivolume.

Another possibility is that the environment variable TAR_OPTIONS
was set to a value that implied ustar format.

Why are you using the -r option?  The -r option is typically not
what users want (even if they think they want it :-).  Among other
things it scans the entire tar image, so it's not particularly
fast.
