Paul,
    I'm sorry I wasn't clear enough.  The 1st disk has NetBSD 1.2.1 
installed,
the 2nd has the new 1.3Alpha.  Neither is mountable after having booted 
the
other!  What I was trying to do was use the disk with the 1.2.1 for 
storing
the tar files (remember I mentioned the disks are small).  Then, after 
booting
1.3, I'd mount that device on /mnt, for example, to make them accessible. 
 As
it turned out, I was foiled by ....whatever?  I suspect what it might be, 
and
just wanted to hear from you all what you think.

Paul
