A replacement drive can then be rebuilt using the data from the surviving drive. Also, because data is duplicated on both drives, two 120-GB RAID level 1 drives collectively have a maximum of 120-GB on which to store data. Configuring Your Computer for RAID At some point you may want to configure your computer for RAID if you did not select a RAID configuration when you purchased your computer. You must have at least two hard drives installed in your computer to set up a RAID configuration. For instructions on how to install a hard drive, see page 85. You can use one of two methods to configure RAID hard drive volumes. One method uses the Intel(R) Option ROM utility, and is performed before you install the operating system onto the hard drive. The second method uses the Intel Application Accelerator, or Intel Storage Utility, and this method is performed after you have installed the operating system and the Intel Storage Utility. Both methods require that you set your computer to RAID-enabled mode before starting any of the RAID configuration procedures in this document.
