I have 3 disks in RAID as RAID 0. All disks are 36.4GB. It a Server 2003 OS. So I wanted to add a new disk just with higher capacity 146 GB. So I downloaded the raid controller utiliy and added the disk to existing RAID 0. When I was working with the utility it recognized that it is a 146GB new hard disk, so when he finished the expansion of RAID 0 he reported the disk as it was the 36.4 GB capacity. I really dont know what is the problem, can someone help me please. SO now it is working fine but the problem is where is the rest of the capacity and can i fix it.

    Is the data on this RAID volume important?  I'm assuming it isn't or you wouldn't be using RAID 0.

    The problem is RAID must use identical sized disks OR, to put it another way, the RAID volume is limited to the number of disks times the SMALLEST disk.  Your smallest disk is 36GB, so if there was a 1 TB disk and you put it in, all you'd see is 36 GB.  Depending on your controller, you MIGHT be able to create an "unraided" 108GB (or so) drive using that extra space.  But there's no way a RAID 0 is going to use the "extra" space on the larger disk for an existing volume.
