2. Select the desired RAID configuration and device format and click Configure.

password to authenticate your action. Enter this information and click OK.
When configuring the device, WD RAID Manager automatically formats the disk as a
single volume using the format and RAID type specified. FAT32 formats with a Master
Boot Record partition map for Windows compatibility.
The HFS+ setting formats with an HFS Extended w/ Journal volume using a partition
map type which best matches the Macintosh model the drive is currently connected
to. On Macintosh computers with PowerPC processor(s), an Apple Partition Map
structure is created. On Macintosh computers with Intel processor(s), a GUID
Partition Table is created.
RAID Troubleshooting
WD RAID Manager monitors the activity of the drives in the RAID system so you can
view the status of each drive and take the appropriate action. To view the device
status as well as the status of each internal hard drive, including which drive (A or B)
may have experienced a fault, click on a device and then click Info, which brings up a
drawer on the right hand side of the main window.
Important: Before you proceed, make sure to back up all files stored on the
dual-drive storage system onto another storage device.
