When You First Start Your Computer - Toshiba S3 User Manual

RAID-1 is configured by creating an array which specifies
the hard disk to be copied, and the hard disk to which the data
will be copied. For your computer, an array will consist of the
computer's primary internal hard disk and the computer's
secondary internal hard disk.
The process of copying data from the primary hard disk to the
secondary hard disk is referred to as mirroring, and the array
itself is referred to as a mirror. If you want to discontinue the
process of mirroring, this is referred to as breaking a mirror.

(mirror)" on page
To create a RAID-1 array, you must use a secondary internal
hard disk with a capacity equal to or greater than that of the
computer's primary internal hard disk. For example, if the
primary internal hard disk is 40 GB, then the secondary
internal hard disk must be 40 GB or greater.
When RAID-1 is configured, the operating system will
display the smaller of the two hard disk drives defined in the
array as the computer's total hard disk capacity. For example,
when a RAID-1 array is configured with one 40 GB hard disk
drive and one 80 GB hard disk drive, the computer's total
hard disk capacity will appear to the operating system as only
40 GB.

When you first start your computer

Each time you start your computer you will be prompted to
configure your computer for RAID-1 until one of the
following occurs:
❖
The computer is ready to enable for RAID-1. See the
steps on the following page.

If both hard disk drives fail simultaneously, such as during a
power failure, the mirrored data on the secondary hard disk
may not be identical to the data on the primary hard disk.
