1. Enter NVRAIDMAN
RAID driver is built in nVidia ALL in one driver provided in our support
CD. After you finish the driver installation, you can create, delete, or
rebuild any RAID array. Please enter NVRAIDMAN by clicking on Start
Programs NVIDIA Corporation Mediashield Mediashield.
(There is also a “Mediashield” shortcut on the desktop.)
Then, the below screen appears.

2. Creating RAID Arrays
Creating RAID 0 (Striping)
NVRAIDMAN can be used to create a striped array from one disk up to
the maximum supported number of disks in the system. To create a two-
disk Striped Array do the following.
1. Go to the system BIOS and make sure that the drives that you want to
use are RAID enabled.
2. Boot to Windows and launch the NVRAIDMAN application.
3. Create Array and the following screen will appear.

3
5. Click the RAID Mode list arrow and select Striping, and leave the
“Stripe Size” with its default value as shown in the following screen shot.
4. Click Next and the following screen shot will appear.

4
6. Click Next, and the following screen shot will appear.
7. Select the two disks that you want to include in the stripe set.
To create a striped array with more disks, select additional disks from the
list.

5
8. Click Next and the following screen shot will appear.
9. Click Finish and the following screen shot will appear.
The RAID 0 is created successfully.

6
Creating RAID 1 (Mirroring)
The NVRAIDMAN application can be used to create a Mirror Array. By
definition, a mirrored array consists of two drives. Data is written to both
two drives, and if one drive fails then data can be recovered from the
other drive. To create a Mirrored Array, do the following.
1. Go to the system BIOS and make sure that the drives that you want to
use are RAID enabled.
2. Boot to Windows and launch the NVRAIDMAN application, then click
on Create Array and the following screen will appear.

3. Click Next and the following screen shot will appear.
4. Click Next and the following screen shot will appear.

5. Select the two drives that you want to use in the Mirrored array.
6. Click Next and the following screen shot will appear.

7. If you want to start rebuilding the array right away (copy data from one
disk to the other), select the disk that you wish to preserve. Do not
select a disk if you do not want to rebuild the array at this time.
8. Click Next and the following screen shot appears.
9. Click Finish. If you selected a disk to preserve in step 7, the rebuilding
process begins.
A mirrored array has been created, while the other two disks are set to
free disks.

10
Creating JBOD (Spanning)
NVRAIDMAN can be used to create a Spanning Array which requires at
least one disk to start such an array. To create a Spanning Array do the
following:
1. Go to the system BIOS and make sure that the drives that you want to
use are RAID enabled.
2. Boot to Windows and launch the NVRAIDMAN application, then click
on Create Array and the following screen will appear.
3. Click Next and the following screen will appear.

11
4. Click the RAID Mode list arrow and select “Spanning” while leaving the
Stripe Size set to its default value as shown in the following screen
shot.
5. Click Next and the following screen shot will appear.

6. Select the two drives that you want to use in the Spanned array.
7. Click Next and the following screen shot will appear.

13
8. Click Finish and the following screen shot will appear.
A Spanned Array has been created.

3. Initializing NVRAID Array Disks
Now that the two-disk array has been created, it needs to be partitioned
and formatted.
1. Click on StartШSettingsШControl Panel.
2. Double click on Administrative Tools.
3. Double click on Computer Management.
4. Click on Disk Management. The following screen is displayed.

15
5. The 153.38 GB is for the two disk striped array that was created earlier.
To create a partition on it, right click on the Unallocated partition and
select New Partition.
6. Follow the Wizard for setting up and formatting the partition. Once that
is done, you can start using the newly created stripped array.

16
4. Deleting a RAID Array
NVRAIDMAN can be used to delete an Array. To delete an Array do the
following.
1. Launch the NVRAIDMAN application and right click on the RAID array
that you want to delete (assuming that you have a RAID array already
created) as shown in the following screen shot.
The above screen shot shows that there is a Mirrored array that will be
deleted. After the “Delete Array...” has been selected, the following screen
shot appear.

17
2. Click Next and the following screen shot will appear.
3. Click Finish and the array will be deleted and the following screen shot
will appear showing all the free disks.
A similar process can be applied to delete any array created by NVIDIA
RAID.

5. Rebuilding a RAID 1 Array
Rebuilding is the process of recovering data from one hard drive to
another. All data is copied from one hard drive to another and then the
data is synchronized between the two hard drives. After creating a
mirrored array, you can rebuild the array using the following steps:
1. Go to Windows and run the NVIDIA RAID Management utility.
2. Right-click on Mirroring. Then the popup menu appears.

19
3. From the popup menu, click Rebuild Array. The NVIDIA Rebuild
Array Wizard appears.
4. Click Next. The Disk Selection page appears.

20
5. Select the drive that you want to rebuild by clicking it from the list, then
click Next. The Completing the NVIDIA Rebuild Array page appears.
6. Click Finish.
More About Rebuilding Arrays
• Rebuilding Occurs in the Background
The rebuilding process takes some time to complete, and occurs in the
background so as not to affect the performance of the system.
• Rebuilding Applies Only to RAID 1
Rebuilding an array works only when using RAID 1. Rebuilding does not
apply to RAID 0 and JBOD arrays.
• Rebuilding applies to a degraded fault tolerant array
You can rebuild a degraded mirrored array using any available Free Disk
or Dedicated Disk.
