A: Make certain:

• The power cables are properly connected to one or both power supplies and to a live power source.
• The Thunderbolt cable is connected to a computer that supports Thunderbolt 2 technology or first generation Thunderbolt technology.
• The computer connected to the LaCie 8big is powered on.
• The power button on the front of the LaCie 8big was pushed as noted in Setting Up.

A: Your LaCie 8big has redundant power supplies. Each power supply provides sufficient power to keep the LaCie 8big running in case the other one fails. Contact LaCie technical support if you believe that one or both power supplies have failed. In the rare case in which both power supplies fail at the same time, you may be asked to send the enclosure to LaCie for review.

A: The device may not be compatible with Thunderbolt products. Unplug any devices you have connected and reboot the product.

A: Eject the volume from the computer and shut down the LaCie 8big by applying a short push on the front button. If nothing happens after a few minutes, you can force the LaCie 8big to turn off by applying a long push (more than four seconds), then release it. Once off, restart the product by pushing and immediately releasing the front button.

Note that a long push is not recommended under standard operating conditions as it may result in data loss. Once the status LED stops blinking blue, check your computer for proper connection to the LaCie 8big volumes.

A: If the ambient temperature is below 40˚C and the ventilation is cleared, you may have one or several malfunctioning fans. Contact LaCie technical support.

A: Check LaCie RAID Manager for the firmware version.

A: Go to the LaCie technical support for the latest information on the product.

A: The installer for LaCie RAID Manager includes a driver to recognize and mount the 8big storage.

A: Disconnect other Thunderbolt devices and see if the LaCie 8big volume appears on the desktop.

A: The hard drive icon(s) for the storage should appear on your desktop. Confirm that the Finder preference for displaying external hard drives on the desktop is selected at Finder > Preferences > General.

A: The connection type for Thunderbolt 2 technology and first generation Thunderbolt technology is the Mini DisplayPort. While older Macintosh computers include Mini DisplayPorts, they are only used to connect one or more monitors. Legacy Macs with Mini DisplayPorts do not support Thunderbolt 2 technology devices such as the LaCie 8big.

A: Review the installation steps (Setting Up). Make certain that both ends of the Thunderbolt cable are firmly connected to the ports and that the device is receiving power via the included power supply.

A: Thunderbolt 2 storage requires cables specifically constructed for Thunderbolt technology. Use the cable that was shipped with your device.

A: The enclosure must also receive power via the included power supply. See Setting Up.

A:

• Only use a cable that supports Thunderbolt technology.
• Check both ends of the Thunderbolt cable to make sure they are fully seated in their respective ports.
• Try disconnecting the Thunderbolt cable then wait 10 seconds before reconnecting it.
• If the hard drive is still not recognized, restart your computer and try again.

A: When copying files or folders from a computer to a FAT 32 volume, certain characters cannot be copied. These characters include, but are not limited to:

? < > / \ :

Since it does not offer optimal performance, LaCie does not recommend using the FAT 32 file system with Thunderbolt 2 technology storage.

A: Ignore this message. The hard drive will remount to the desktop.

A: Hard drive space will be reclaimed once files are erased. To remove the files forever:

• Click the Trash icon in the Dock.
• A Finder window will open. Click Empty in the upper right.

A: The LaCie 8big must be connected to a computer that supports Thunderbolt 2 technology to attain Thunderbolt 2 technology transfer rates.

A: Thunderbolt 2 technology devices can share the same daisy chain with first generation Thunderbolt technology devices. However, the LaCie 8big can only reach Thunderbolt 2 transfer rates if it is connected directly to the computer with the other devices daisy-chained behind it. If your computer supports Thunderbolt 2 technology, make certain that the LaCie 8big is the first device in the daisy chain.

A: Thunderbolt 2 technology devices can share the same daisy chain as a display. However, the LaCie 8big can only reach Thunderbolt 2 transfer rates if it is connected directly to the computer with the other devices daisy-chained behind it. If your computer supports Thunderbolt 2 technology, make certain that the LaCie 8big is the first device in the daisy chain.
