[X4U] Storage on mirrored external drive

[Said Nuseibeh]

Hi Listers,

If I mirror my g4 laptop (10.4.11) on a bootable external FW drive that
has greater hard drive capacity, and I want to use that remaining space
to incrementally store new data, where should I put that data so as not
to interfere with system operations if --in the case of mishap-- I ever
have to boot from that external disk?

I used to put data in the Public folder to (theoretically) avoid
Permission problems. Now that hard drives are so much bigger, I have
found that the Public folder on my mirrored drive shows a capacity
identical to the original drive at time of cloning (SuperDuper). Where
did the extra 400GB go???

Anybody have experience in this matter? Can I put a folder in the top
directory and continue to access these files from other machines AND
boot from that drive? Or is there another more optimum solution.

Thanks,
