Tape Backup Problems a/ux 1.0 - 1.1

[wmd at tippy.uucp]

I have A/UX 1.0 and am expecting 1.1 soon.  I have a 300 meg internal
hard disk with A/UX on an external 80.  When I partitioned the 300 meg disk
I did not create a Mac OS partition, just a UNIX one.  Here is my problem.

To back up the system on tape I boot the Mac OS and use the newest version
of Tape Backup.  Problem is that upon booting, the 300 meg drive does not
appear on the desktop (presumably because it has no Mac partition).  That
in turn, prevents Tape Backup from recognizing its existance, therefore
it doesn't display its partitions as being available for backup.

How do I back up the drive with Tape Backup?

Can I create another (Mac OS) partition without damaging any data on the disk?

Will this cause the Mac OS and Tape Backup to recognize the disk?

What procedure should I follow?  any suggestions...
