Hi, Disk Mirroring is a term used in conjunction with RAID, where the automatic recording of redundant data is performed to allow for fault tolerant operation. Data are written on two partitions of the same disk or on two separate disks within the same system. Disk mirroring uses the same controller. RAID 1 http://en.wikipedia.org/wiki/Standard_RA… provides for mirroring, which is usually accomplished with SCSI drives and, increasingly, with SATA IDE drives. Disk cloning http://en.wikipedia.org/wiki/Cloning is a term that implies the manual process of physically generating an exact copy of one hard disk to another. Should you choose, then you can follow all the good advice on ‘cloning’ with Ghost or you can go the automatic route if you have an SATA drive. Some motherboards include a Raid adapter.
