Thanks for the quick response from everyone. My solution was the same as
the previous summary I had so foolishly deleted :). Used /usr/ucb/tcopy to
determine block size, then tar was able to read the tape. Apparently tar
cannot automatically determine the block size during extraction if the tape
is created on a non-UNIX machine. (My tape was created using tar, I found out
later.)

Special thanks to the following:
