Repairing Degraded RAID
I have taken over support for a new client and in initial review of SBS box noticed that Disk Management is showing that a Mirrored Volume is showing 'Failed Redundancy' with Errors on one of the disks. As it turns out the disk is quite old (infact ancient) as it is a 120GB 7200RPM Barracuda.
What are the next steps?
Do I attempt to rebuild the array? I assume that the utility I use would be on boot up, rather than through windows as it is more than likely a hardware controller?
Do I go straight for a new drive and swap out? I was under the impression that I needed an identical drive for the array to rebuild, but I see posts about being able to use a larger drive, but the RAID would only recognise it as a 120GB (or use 120GB). This is fine for me as they have a new server on its way in 18 days, so just looking to get through safely.
Thoughts?

Thanks siht.
I will not be onsite with the server until tomorrow, but can RDP in if necessary. Knowing only this, how can I determine if the RAID is Windows based or Controller based?

Backup is already taken care of, but thanks for the reminder.
Cheers for the advice - does not seem too difficult.

You might have trouble finding a 120GB drive these days anyway as stroage sizes have increased.
You'll want to initiate the rebuild from the controller if it is a controller based RAID. DO you see a RAID BIOS showing your degraded array at boot? If you don'y it may be a Windows based RAID and you'll want to initiate the rebuild from disk management.
The process should be self explanatory once you have installed the new drive.
