Page 12: Rebuilding A Redundant Drive
9. Rebuilding a redundant drive The 8-BAY RAID Enclosure protect against data loss due to drive failure in R50 mode. The following example illustrates the procedure of rebuilding a failure drive. 1. This example is based on drive 2 failure.If drive 2 fails, please remove it from the device (Fig.16). - Page 13 3. Replace the defective HDD with a hard disk drive of the same capacity or bigger (Fig.18) Fig.18 4. Power on the device (Fig.19). Fig.19 On/off button 5. The 8-BAY RAID Enclsoure will start rebuilding the RAID volume automatically (rebuild speed: approximately 200 GB/hour, depend on data usage).

10. Troubleshooting 1. Device is not recognized Make sure all cables have been properly connected. For the USB 3.0 controller the latest drivers and the newest firmware must be installed. USB 3.0 controller may also need to power on based on the controller design. 2. -
Page 15: Appendix
11. Appendix 11.1 LARGE mode (Spanning) Function : The LARGE mode concatenates a series of physical hard drives into a single large volume, creating a seamless expansion of virtual volumes beyond the physical limitations of singularly connected hard drives. Notes : The hard drives 1 to 8 are concatenated into a single virtual volume in the Figure above with a storage capacity that is equal to the sum of each of the physical hard drives 1 to 8. -
Page 16: R00 Mode
11.2 RAID00 mode Function : In RAID00 mode the data is spread across all hard disks. Example 1 Advantage/disadvantage : RAID00 mode provides the highest data speed but no data redundancy. RAID00 mode accelerates hard disk drive operating speed by using many disks simultane- ously. -
Page 17: R50 Mode
11.3 RAID50 mode Function : The R50 mode adds fault tolerance to drive striping by including parity information with the data. R50 mode dedicates the equivalent of one drive for storing parity stripes. The data and parity information is arranged on the drive array so that parity is written to all drives (SYS1 and 2). - Page 18 Notes : Although the volume remains available during the rebuild process, the volume is in degrade and possible data loss if more drives fail. Host access takes higher priority over the rebuild process to allow data backup and continues usage. If you continue to use the virtual R5 volume during the rebuild, the rebuild process will take a longer time to complete.
