*A "RAID Ready" system is a specific system configuration that enables a seamless migration from a single non-RAID disk drive to a dual disk drive RAID 0 or RAID 1 array.
**For boards using ICH7R, ICH8R, ICH8DH or ICH8DO chipsets, a maximum of 4 drives can be used in a single RAID 0 or RAID 5 array. A maximum of 2 drives can be used in a single RAID 1 array. The other SATA connectors can be used for single drives or to create another RAID array.
Serial ATA and Microsoft Windows*
Microsofts* paper, Serial ATA in the Microsoft Operating System Environment*, provides additional information about Serial ATA support for the Microsoft Microsoft Windows* family of operating systems.
Serial ATA DVD/CD Drives
Currently, SATA speeds are not significantly that much faster than the older PATA interface (150 MB per second as opposed to PATA's up to 133 MBps), it promises to eventually attain speeds of up to 600 MBps.
| Note |
Intel® Matrix Storage Manager supports SATA 3.0 Gb/second. | |
However, these speeds are relevant only to hard drives. These numbers aren't meaningful to optical drives. Optical drives generally top out at about 22 MBps for reads and 16.5 MBps for writes, far below the level of PATA'S current capabilities.
SATA has some advantages that apply to DVD drives:
- It uses slimmer cables, which improve circulation within the PC and keep the insides cooler.
- You connect only one device per cable, which eliminates the need for master/slave/cable select jumper settings and simplifies drive installation.
- It allows up to 3.3-foot cable lengths as opposed to PATA's 1.5-foot limitation.
Mixing SATA and PATA (IDE) Devices
SATA and PATA devices can work together in a single system. Typically, the SATA connectors would be used for hard drives and the PATA connector would be used for DVD or CD (optical) drives, although hard drives can be installed on both connector types.
Intels RAID configuration software offers the ability to create RAID volumes manually. This option should be used if you are using a third bootable device such as an IDE or SCSI hard drive in addition to using two SATA hard drives. To create a RAID volume manually, see the section titled "Create Volume Manually" in the Users Manual.
One benefit of using a third bootable device and creating a RAID volume manually is that the operating system is not located on the RAID volume. Should something happen to the RAID volume, the operating system should not be impacted.
Enabling RAID in the BIOS
The RAID option must be enabled in BIOS before the system can load the Intel RAID Option ROM code.
- During boot, enter the BIOS setup by pressing F2.
- Go to Advanced > Drive Configuration.
- Depending on your board model, the option to enable RAID may be either of the following:
- Set Configure SATA As to RAID
- Set Drive Mode to Enhanced and set the RAID option to Enabled. (Terminology can differ by board model; may show as SoftRAID or Intel® Matrix Storage Technology.)
- Press F10 to save setting and exit the BIOS Setup program.
If you do not find settings in the BIOS to turn on RAID, double check your desktop board model to make sure it is supported.
SATA Modes (AHCI; Hot Swap)
The SATA controller has three modes of operation:
- IDE mode - no AHCI, no RAID
- SATA mode (sometimes called AHCI mode) - AHCI enabled, no RAID
- RAID mode - AHCI enabled, RAID enabled
AHCI mode also allows for Hot Swapping drives.
Switching SATA modes in the BIOS after installing the operating system is not recommended when a SATA drive is the boot drive. Switching modes may cause an immediate blue screen with an 0x0000007b error code, followed by a reboot.
For complete information on the SATA Mode, refer to Changing and/or choosing SATA modes.
Configuring RAID on a New PC
You can configure your new system for RAID and install the Intel® Rapid Storage Technology driver during the Microsoft Windows* operating system installation. Refer to the Users Manual for complete steps.
Configuring RAID on an Existing PC
Intels RAID configuration utilities offer the flexibility to upgrade from a single Serial ATA (SATA) hard drive to a two drive RAID 0 or RAID 1 configuration when an additional SATA hard drive is added to an existing PC. With Intel® Rapid Storage Technology, you can also migrate to a 3 or 4-drive RAID 5 or a 4-drive RAID 10 configuration on ICH7R systems.
Refer to the Users Manual for complete steps.
Unattended Installation Instructions Under Microsoft Windows* XP
For instructions on doing an unattended installation with the Intel® Rapid Storage Technology software under Microsoft Windows* XP, refer to Unattended Installation Instructions Under Microsoft Windows** XP.
Troubleshooting
Serial ATA Drive Not Recognized
There are several reasons why a serial ATA drive may not be recognized at bootup or by the operating system.
No Power to the Drive
Check that the power cable is connected from the power supply to the SATA drive. If your power supply does not include a SATA power connector, you will need an adapter.
SATA Data Cable is not Connected
Check that the SATA data cable is firmly connected from the SATA drive to the SATA header on the desktop board.
SATA Drive is not Formatted
Like all drives, serial ATA drives must be formatted before use.
BIOS Issues
Random BIOS problems may interfere with the detection of SATA drives.
- Make sure you have the latest BIOS version for your desktop board.
- Try a BIOS recovery.
Ctrl-I Option to Open RAID Configuration Utility Does Not Appear
After configuring the BIOS for Intel® Rapid Storage Technology, upon reboot you will see the Option ROM status message on the screen: Press <CTRL-I> to enter RAID Configuration Utility.
If the BIOS setting for Addon ROM Display Mode is disabled, the CTRL-I message may not appear. To resolve this:
- Enter the BIOS Setup by pressing F2 during boot.
- Go to the Boot menu.
- Enable Addon ROM Display Mode.
- Save and exit the Bios Setup.
| Note |
If you are in AHCI mode or have only a single SATA hard drive installed, the Option ROM will not load and you will not be able to enter the RAID Configuration Utility. | |
Nothing Happens when Pressing F6 During Microsoft Windows** Setup to Load 3rd Party RAID Driver
If you have enabled RAID, at the beginning of Microsoft Windows* Setup, youll see a prompt to Press <F6> to install a third-party SCSI or RAID driver. When you press F6, it may appear as if nothing happened as a dialog box will not appear and you will not immediately see a prompt. You likely will not see any sort of dialog box appear at the time you press F6. Instead, later during Microsoft Windows* Setup, however, you will be prompted to insert the RAID driver floppy disk that came with the desktop board.
Serial ATA Drives Disappear from RAID Array
Refer to the Troubleshooting chapter in the Users Manual for complete steps in troubleshooting failed drives.
137 GB Drive Size Limitation
The original Microsoft Windows* XP or 2000 CDs can only support a maximum hard drive capacity of 137 GB. To install a hard drive larger than 137 gigabytes on your computer you need Microsoft Windows* 2000 Service Pack 3 or later or Microsoft Windows* XP Service Pack 1 or later.
SATA Controller Not Running at 150MB per Second
Intel® Desktop Utilities may report that Serial ATA drives are running at ATA speeds (ATA/100 or ATA/133). This is because the Serial ATA controller is running in Emulating Parallel ATA mode and is using Microsoft Windows* parallel ATA drivers (i.e. atapi.sys). While the Serial ATA controller may be operating at a higher transfer speed, it may claim to be operating in a slower parallel ATA transfer mode. All versions of Microsoft Windows* prior to Microsoft Windows* Server 2003 have support for Emulating Parallel ATA mode. For additional information refer to Serial ATA in the Microsoft Operating System Environment.*
USB Floppy Drive Does Not Work to Install Mass Storage Drivers
This issue may occur if the USB floppy disk drive is not supported for use during Microsoft Windows* XP installation. For more information, refer to Microsoft Article ID 916196*.
Serial ATA Port Numbers Do Not Match
On Intel® Desktop Boards based on the Intel® 965 Express chipset, the serial ATA port number listed in the Intel® Rapid Storage Technology option ROM and the user interface does not match the port number listed in the system BIOS and on the desktop board itself. As an example, a drive reported as connected to Port 2 in the user interface will be identified by the BIOS as being connected to Port 4.
Use the table below to map the port number shown in the Intel® Rapid Storage Technology option ROM and Intel® Matrix Storage Console to the port number shown by the BIOS and board markings. This will be necessary in the event of a drive failure in order to ensure the replacement of the correct drive.
| Caution |
When replacing a failed drive within a RAID array, refer to the drive number as shown in the Intel® Matrix Storage Console. Do not replace a failed drive according the board silkscreen markings. | |

1When RAID is enabled, you cannot check which port a drive is connected to in the BIOS. The BIOS will show the individual SATA ports, but all of them will show "Not Connected" even if there are drives connected. You can only check it from the option ROM, the Intel® Matrix Storage Console and the board silkscreen.
Optical Drives Connected to Blue SATA Ports Do Not Work
With the Intel® Desktop Board D975XBX2 or DX38BT, CD or DVD drives connected to the blue SATA ports may not be recognized by Microsoft Windows*. This can result in failures when trying to write to CDs or DVDs in the drive. To resolve this, connect the optical drive it to a black SATA port.
