I'm trying to install a Caldigit Raid card. My Current setup pre Raid is: 1st Drive -150GB 10k rpm - OS X 2nd Drive - 150 GB 10k rpm - WINDOWS OS 3rd Drive - 1T - Library - About 800GB used 4th Drive - 1T - Backup - using Super Duper to back the library up every night. The way I want to have it setup is 4 x 1.5T in RAID 5. Get rid of Windows and only have OS X running in there. Caldigit raid card won't let you do a fresh install in a new drive. You must have a a drive with OS in the first bay with Caldigit drivers installed in order to run successfully. That means that I have to install drive 1 and 3, install the drivers on there, clones drive 1 and 3 (which my understanding is not possible), boot from external build the raid, and clone it back to internal drives. Drive 1 hold OS, but since 3 has all the files, my credentials are all in there. The computer won't let me just boot with only drive 1 in there, thus the reason why I need to clone both drives. So I tried, doing a fresh install on a new hard drive w/o the caldigit card in the computer I'm getting the multi langague screen before the cd fully loads. I am 99% sure that I have the 10.5.2 cd trying to do the fresh install. Doing a fresh install is now out of the question. I've tried the CMM+OPT+P+R and CMM + OPT + O + F as well, but nothing happens. Meaning that I think those commands are not working at all in my PC. This is with fresh drive and os 10.5.2 in the cd tray. What are my choices here? Can I make a new credential in my OS drive and point it to the OS HD, clone that, and build my RAID? Any help would be appreciated. Thanks!
