Removal and installation of the second hard disk must only be performed by

authorised service agents of Fujitsu Siemens Computers GmbH. Unauthorised

removal and installation will invalidate your warranty.

RAID (Redundant Array of Independent Disks, also: Disk Array) is a procedure for

combining two hard disks to create a logical unit.

A so-called disk array can be used advantageously to improve performance or

alternatively to improve error tolerance (data protection).

Error tolerance is facilitated by means of data redundancy. If one drive malfunctions,

a different drive con tain s an exact copy of the data. This can prevent an operating

system from malfunctio ning or data from being lost.

The o perating system detects all hard disks in a disk array as a single physical

hard disk. The individual disk drives in a disk array are called "members". Member

conﬁguration information is recorded in the reserved sector of the hard disk. With this

information the hard disk can be identiﬁed as a member.

There are usually a few methods by which hard disks can be combined. These methods

are referred to as d ifferent RAID levels. The different RAID levels represent different

performance and security levels as well as implementation costs.

Depending on the size of the hard disk, the process for c ombining two

hard drives to create a RAID group can take several hours. During this

time period, your screen will turn black.
