User Guide
SAFE: This mode requires 2 identical drives to implement, otherwise the total amount of the space that can be used will depend on the drive with the smallest capacity. 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 Error LED indication at the front to show when one of the drives can not be accessed anymore. When a drive fails, the corresponding LED will flash red and green in intervals. 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. If HDD1 is defective, remove it, connect the second HDD to HDD1 and then install a new HDD at HDD2. If HDD2 is defective, replace the drive with a new HDD.
3.Finish the assembly and connect the power supply.
4.Turn the power ON and let it rebuild the data. It will automatically copy all the data from HDD1 to HDD2 to create a backup.
5.The HDD LED will flash red just like during data access as long as the data is being rebuilt. This process will take several hours, depending on the capacity of your hard drives.
6.When all the data is backed up, the LEDs will turn green.
Note: The LED indication for HDD1 is referring to the hard drive connected to CN2, which is the main drive. The LED at HDD2 is referring to the backup drive at CN1.
