Ok There are 3 fijitsu hdd on this server. I could install windows 2008 server beta by using Intel® Deployment Assistant CD. While booting I used control+H to configure and create virtual raid disks using LSI MegaRaid Bios Configuration utiity. I did the automatic mode so it took two hdd and left one. In other words it used 67 + 67 GB of space (two hdd) and left one. It used raid 5 system. Now I want to use the other HDD (67gb). How should I do?
