  	My '040 Cube is running NeXTstep 3.3 with CAPer,
so if I made
 images I could easily move them on to my main Mac for storage.  The
 distribution disks in question have NS 0.9, 1.0, 1.0a, 2.0, 2.1, and
 3.0, as well as a non-bootable disk of 3.2.  They've been verified as 
 readable and still containing the OS (on my '040 Cube after being 
 locked).  Due to the unknown quality of the OD in my '030 Cube I 
 really don't want to try and boot one on it and I'd like to get them 
 to another media before I lose the ability to
 read them altogether. 
Well, after reading your post two or three times, and 
not finding a question in it, I'm going to try to answer 
anyway. :)

I'll assume the questing is something like:

"How on earth do I make a copies of the distribution
disks onto different media?"

Anyway, what I would do is to make an image, using dd, 
of one of the disks, and then try to put it on the 
external drive.  See if you can boot it from there,
and then read the image back from the external drive
and make sure it hasn't changed.

If that works, repeat the process.  I would also try
burning the image onto cd with cdrecord (for instance),
if it's possible.  That may just turn out to be another
option.  The added bonus here is that CDs are common as
dirt.
