RAID Mode The enclosure can be set to function in one of four modes; Normal, JBOD, RAID 0, and RAID 1, giving you the flexibility to access your data in whatever way works best for you. The available modes are described below, with their corresponding dip switch setting displayed on the left side of the image. Normal Mode – This mode treats both hard drives as separate disks, allowing them to be accessed independently of each other. Your computer will recognize them as if they were flash drives being plugged into separate USB ports, not changing them in any way. 2 Disk Volume 2 Disk Volume SATA1 1000G SATA2 750G SATA1 1000G SATA2 750G JBOD Mode – This mode combines the two hard drives into one large drive for the purpose of increased storage space. Data is stored on one drive at a time, so when the first one is full, the next one begins to be used. The computer’s operating system will recognize them as a single drive.
RAID Mode RAID 1 Mode – This mode creates two mirror disk drives for the purpose of data redundancy. If one drive fails, the other drive serves as a back-up. When using this mode, it is recommended that you use hard drives with the same capacities. If hard drives of different capacities are used, the storage capacity will be limited to that of the smaller drive, with the remaining space on the larger drive going unused. Note: In RAID1 mode, if one of the drives fails, the Red LED to the right of the hard drive tray will blink. Replacing the drive will cause the enclosure to automatically enter rebuild mode, in which the Red LED will continue to blink to indicate that the RAID1 array is being rebuilt.
Setting the RAID Mode When Powered Off: 1. Install the hard drives in the enclosure according to the installation instructions in this manual, but do not power on the unit. 2. By default, the dip switches on the back of the unit are both set to the OFF (Up) position, which will display the hard drives in Normal mode. 3. Set the dip switches on the back of the unit according to the desired mode. See the RAID Mode section in this manual for each mode’s dip switch configuration. Note: When changing from RAID 1 mode to another mode, you must first switch to RAID 0 mode. Once set to RAID 0 mode, you can change to any other mode. 4. After setting the dip switches accordingly, power on the unit.
