Oops. You're right of course. I shouldn't answer posts before having my
morning coffee:-)

Thanks all for the replies, tho it is not neccessarily what I wanted
to hear. But it won't be the end of the world if I lose it all (just a ton
of
work that was done making it) ..

The raid in question is just BACKUPs already .... it happens to be
my entire dvd collection which I have backed up on my computer.
So, if I lose the raid, then I will just have to rerip them all again.
I was just looking to see if it was possible to AVOID having to do
that.

(p.s. for what its worth, I am using a Raid (JBOD) config for this merely
for convienence sake, so I have just ONE volume (in my eyes) on here for
my (dvd) storage, and not have them scattered about on 4 or 5 diff
volumes/partitions)

Thanks again

You will have to start from scratch when you add the 300gb drive, no way to
know what data is where. But the solution is quite simple, just backup all
your data, yank the 73gb drive, add the 300 and load the data back. If you
don't have a method of backing up your data then why would you need all that
storage if you don't care if you loose it or not.

Almost certainly. And when changing stuff, it's wise to take a backup
of ALL your data.
