With a Mirrored Raid, you will not be able to see the drives individually (the physical drives) by looking in my computer or even disk management. You will only see the "logical" drive in these areas. The only way to see the physical drives is to either get back into raid utility where you set up the raid. If you have the ACU (array configuration utility) installed, you can access that utility while you are booted into the server's OS and can view the physical drives there. Since you have set up a mirrored Raid, that 2nd 250GB hard drive is only for the backup of your first drive, and cannot be accessed seperatly, nor will you see any added storage space (you will only see 250GB instead of 500GB since one of the drives is an exact copy of the other drive)

If you would do a software RAID then you would be able to see the mirrored disk in 'disk management' in Windows. But if you do it with hardware RAID then the OS only sees what the hardware RAID presents to the OS:

HP ML 110 G5 w onboard RAID controller
- Array 1: Boot (1x150GB RAID 1) << working fine
- Array 2: Data (1x1TB RAID 1) << new, configured and verified in BIOS RAID utility but not visible in Win 2008 R2 64-bit
When I load Disk Management in Win 2008 the new *logical* disk does not appear.
I have updated the onboard RAID driver but that didn't help:
- HP Embedded G5 SATA RAID Controller Driver for Microsoft Windows Server 2008 x64 Editions (cp015552.exe)
Can anyone help? What is the problem?!
Thanks in advance.

RAID 0 is an option but I wanted to create a RAID 1 array for redundancy. The controller appears to work - it creates a RAID 1 array but I think there's a compatibility problem with using Seagate Constellation ES 1TB drives. Although the new RAID 1 array is active and verified (took 20 hours!) you still can't see the logical disk in Windows Drive Manager. Others have found out that Seagate Barracuda drives work.
