I have up to now partitioned my
internal HD in to 3 partitions. OS, Data
and a second OS. The second OS is a
backup (via ChronoSync) of the main OS. I
do this as I am on the road a lot with my PWB and if my system gives up I can quickly
switch partitions and work again.
Now if I install Catalina it will
create a second partition on the partition that has my OS on it. So far so good.
Now if I
want to maintain my structure as I have been having it up to now (3 portions on
the internal HD) how do I do that? I can
erase the present Data partition and give the space to both OS partitions, no
problem. But as soon as I install Catalina on the
second partition it will create a virtual volume. Now I have two places where data is stored
and wasted space. And this I did not
have in the past, as the second Data partition was available to both OS
has an idea as to how to work with that?
