I am new to the G5XServe...but wanted to software mirror 2 of the 750Gb drives, and then partition them, one partition to be 300Mb, the other effectively 400Gb, but I can't seem to get this completed. It seems like I cant create the partitions with the Disk Utility.. Anyone have any ideas... I have WD drives, and have heard of something called WDRaidManager, but cant seem to find it on the WD site.. Any assistance would be appreciated...as I need to get this G5 up soon. thanks..
