Disk size changes after installing windows server 2008

Dear Experts,

Our server has 16 bays,

14 Bay = 300 GB (Date), RAID 50, ~3.3 TB
2 Bay = 146 GB (System) Mirror, 140 GB

Windows 2008 installation is on System drive.  After installation complete, everything changes. system drive takes some of Data drive as you see from the attached image, and Data drive get divided in to two partition, I can’t even separate them.

Why this happens?

Hi uknet80

I notice your data disk is "disk 0" and you system disk is "disk 1".  This is not best practice as the system disk would normally be disk 0.  In your RAID array the two 146GB system disks should be in the first two drive bays (normally 0 and 1, or 1 and 2).  This should cause the system disk to be "disk 0" and will prevent the OS from taking part of your data drive.

If that doesn't work, delete the data drive from thew RAID controller, install the OS on the system disk, then create the data drive on the RAID controller after the OS is installed.
