8. Data Rebuilding Operation

The Hot Swappable hard drive and Auto Rebuilding features are available.
Off-line Back up：When the data is stored in iR2823/IR2824, user can remove one of the hard drives
as back up drive for data such as system operation file, secured files, seldom modified files or image
and music files. The user can periodically insert the hard drive back into iR2823 / iR2824 to execute
automatic backup to protect the system from being hit by computer virus or to avoid the risk of having
both hard drives failing at the same time.
When one of the two hard drives fails in iR2823/IR2824, it will issue an alert of a hard drive failure
message in both LCD display and the monitoring software. User can remove the failed hard drive
from the system while the system is still in operation without shutting down the machine. If the failed
hard drive is replaced shortly, the system will automatically execute the Auto Rebuilding function
without affecting the system operation and also any operation command from the user.

the LCD displays the following messages：
