Taurus - RAID User Guide
The LED indication
for HDD1 is
referring to the HDD
on top, where
HDD2 is the one at
the bottom.
RAID 1 - Mirroring: This mode requires 2 identical drives to
implement. A RAID 1 creates an exact copy (or mirror) of a set
of data on the second drive. This is useful when reliability and
backup are more important than data capacity. The available
capacity to the user will only be as large as a single drive but
when one of the hard drives fails, it can be replaced and the
data rebuilt automatically.
The Taurus enclosure has an LED indication at the front to
show the status of the hard drives. As long as both HDD1 and
HDD2 are working OK, the LED is green. When a drive fails,
the corresponding LED will turn red. To replace the faulty drive,
do the following:
1. Turn off the Taurus and remove both the power supply and
the interface cable.
2. Open the enclosure and replace the faulty hard drive.
3. Finish the assembly and connect the power supply but do
not connect the interface cable to your computer yet.
4. Turn the power ON and let it rebuild the data. If it rebuilds
from HDD1 to HDD2, the rebuild LED will flash yellow, where
from HDD2 to HDD1 it will flash green.
5. Wait for the rebuild LED to stop flashing.
6. When the rebuild is finished, connect the interface cable to
your computer. Done.
Note: Rebuilding the data might take several hours, depending
on the capacity of your hard drives. As reference, an 80GB
HDD will take about 2 hours to rebuild.
