Configuring a Hot Spare
If you have 3 drives in a RAID 5 array, or 2 drives in a RAID 1 array, then you can configure another drive as a hot spare.  If 
one of the drives in the array fails, the TeraStation will switch over to the hot spare immediately.  
Note: 
If a hot spare is configured, click [Set to normal disk] to change the hot spare to a normal disk.
 The [Confirm Operation] screen will appear.  Enter the number shown in the [Confirmation Number] field within 
60 seconds and click [Apply].
Follow the instructions displayed on the screen.
You have now configured a hot spare.
Note: 
 
All data in the hot spare drive will be deleted when it is configured as a hot spare and again when it changes over from a 
spare to a drive in the array.
Choose a RAID 5 or RAID1 array.
Click [Set to spare-disk].
Click [System] - [Storage] - [RAID Array] in the Web Admin interface.
