Single Disk to RAID 1?

[loustarrrr]

Hi,

We have a server running Windows Server 2008. It hosts our SharePoint 2010 site and has recently been giving us bad block error messages in event viewer.

An example being,
The device, \Device\Harddisk0\DR0, has a bad block.

Would it be possible to resolve this by putting in a blank hard disk and allowing the built in RAID on the server to mirror the existing disk to a new one to avoid having to re-build the server and restore all data?

No, a RAID controller would detect the bad sectors and mark the drive as failed.

I's say the safest bet would be to either try taking the server offline and using gparted or something similar to try and clone the disk to another, or else run a full server backup and restore to a new disk.

In future, I'd never run production services from unresilient storage

I would go with take a clone of the drive. Install new drives in a raid and then cloning the server back.

You can make a software mirror (inc os) in 2003, I can't imagine you couldn't in 2008?

or else run a full server backup and restore to a new disk.

I'd go with this option, should be straight forward enough for you.
