Hello and thanks Wayne! I hadn't thought of keeping the RRAbuntu machine in operation as a server. I had simply wanted to take the 2nd drive in that RRAbuntu machine that has all our sound files on it, and is currently mapped to /var/snd in that machine and put it into the new CentOS/Rivendell machine.
If I am understanding things, we'd do that via fstab, but first I must get CentOS to see this 2nd drive when it's installed in the computer. When I installed hwbrowser I can see a 2nd drive in the CentOS / Rivendell computer, but I can't seem to figure out how to mount it so that the GUI or OS sees it. That's why I was wondering about Disk Utility. So, if all I wanted to do was to mount this 2nd drive into the CentOS machine, and either map it to /var/snd or simply copy the RDLibrary files over to the 1st drive (the one with the OS which does have enough room on it, it's 1TB), what would you recommend? and, a MILLION thanks for your help, kind sir!
