User manual VERBATIM 2-DISK RAID USB-ESATA EXTERNAL HARD DRIVE

[. . . ] Once the AC Adapter has been properly connected to the drive and an AC outlet, you can press the ON/OFF button to power on the drive. Do not change the setting of the RAID Mode Switch unless you have first saved all of the data from the drive to another storage location. 5 About the Hard Drives The product comes pre-formatted in FAT32 format. This format allows for operation with either Windows or Mac OS. Note: Capacity dependent on model. 1 MB = 1, 000, 000 bytes/ 1 GB = 1, 000, 000, 000 bytes/1 TB = 1, 000, 000, 000, 000 bytes. [. . . ] If Concatenation is your desired mode, then you can jump to the next section of the manual since no further configuration is required. Do not change the setting of the RAID Mode Switch unless you have first saved all of the data from the drive to another storage location. 7 RAID 0 (Also called Striping) distributes data across both disks in a way which can improve throughput, while retaining full capacity. However, in case of possible failure of either disk, all data will be lost and the array will no longer mount to your computer. If either disk fails in RAID 0 then the LED of the failed drive will change to RED. RAID 1 (Also called Mirroring) stores a duplicate set of data onto both disks, so that if one disk fails all data can be recovered from the other disk. Available capacity is equal to that of only one of the two included drives. If either disk fails in RAID 1, then the LED corresponding to the failed disk will change to RED. The remaining operational disk can continue to be used until the failed disk has been replaced. However, in this instance there is no longer any data protection provided by the second, failed drive. If you have been using RAID 1 mode and there is a subsequent failure of either of the two drives, you can disassemble the enclosure and replace the failed drive with a new drive. After reassembling the enclosure, leave it disconnected from your computer and power it up. When the new drive is detected during the power-on sequence, the full data of the original drive will be rebuilt onto the new drive. This rebuilding procedure can take many hours (more than 5!) to complete. During the rebuilding procedure, the LED of the original good drive will flash BLUE, while the LED of the new replacement drive will flash RED. After the array has rebuilt successfully both LEDs will change to BLUE. Concatenation (RAID Mode Switch Setting = "BIG") combines both physical disk drives into a single virtual disk. If either disk fails in Concatenation mode, then the array will no longer mount to your computer. If either disk fails in Concatenation mode, then the LED corresponding to the failed disk will change to RED. 8 To change RAID mode, follow these steps: 1. If you have any important data stored on the drive, first save the data to another storage location. While power is OFF, use a pen or other instrument to slide the RAID Mode Switch to the desired position. The LEDs will flash BLUE while the internal firmware is reconfiguring the RAID mode. When flashing turns to solid BLUE the drive has successfully reconfigured, though remains initialised, unpartitioned and unformatted. Your computer may show it as an unknown device, which confirms that the drive remains initialised, unpartitioned, and unformatted. For NTFS or HFS+ use the computer's operating system to reformat.
