Why mirror hard drive on Windows Server 2008?
“I have a Windows Server 2008 machine with 2 physical and basic hard drives, not RAID. Disk 0 is with system installed, and disk 1 is a new and empty disk bought a couple of days ago. I have an exact copy of the system on disk 0, which I intend to use as a disaster recovery solution in case my Server 2008 fails. I’d like to mirror disk 0 now to the new disk, so that when hard drive fails, I’ll just swap it with the latter. Is this possible? If it is, what would be the simplest way to do this?”

Some users report that the mirrored system drive won’t boot when clone hard drive in other ways. There are three main reasons account for this:
Used cloning software is not professional, so that some important partitions like system reserved partition or EFI/UEFI partition not cloned during the process.

Two methods to mirror hard drive on Server 2008
AOMEI Partition Assistant Server serves “Sector by sector copy” method that allows you to make an intact clone of source disk. In the meantime, the deleted and formatted volumes/files will be retrieved to the destination disk. This method takes up much more time than regular clone, and it has a rigid requirement that the destination disk has to be equal to or larger than the source.
The other cloning method in AOMEI Partition Assistant is quite simple and time-saving. “Copy Disk Quickly” will clone only used part on source drive to destination disk, which makes clone large drive to smaller drive on Server possible. During the copy steps, you have options to adjust partition size in three ways: Copy without resizing partitions, Fit partitions to entire disk, and Edit partitions on this disk.
The software has easy-to-use copy wizard, which is suitable for computer green hands in particular. You can choose different methods based on your own situation. Next part details steps with screenshots on how to clone hard drive on Windows Server 2008 with sector-by-sector copy method.
