A: Disconnect any other Thunderbolt devices and see if the Thunderbolt Series volume appears on the desktop.

A: The drive icon(s) for the Thunderbolt Series storage should appear on your desktop. Please confirm that the Finder preference for displaying external disks on the desktop is selected at Finder > Preferences > General.

A: The connection type for Thunderbolt technology on the Mac is the Mini DisplayPort. While earlier Macintosh computers include one or more Mini DisplayPorts, they are only used to connect one or more monitors. Please note that legacy Macs with Mini DisplayPorts do not support Thunderbolt technology peripherals such as the LaCie Thunderbolt Series storage.

A: Review the installation steps (Getting Connected). Please make certain that both ends of the Thunderbolt technology cable are firmly connected to the ports and that the device is receiving power via the included power supply.

A: The Thunderbolt Series storage requires cables specifically constructed for Thunderbolt technology. Go to www.lacie.com for more information on cables that support Thunderbolt technology.

A: The Thunderbolt Series enclosure must receive power via the included power supply. See Getting Connected.

A:

• Only use a cable that supports Thunderbolt technology on a Mac.
• Check both ends of the Thunderbolt technology cable to make sure they are fully seated in their respective ports.
• Try disconnecting the Thunderbolt technology cable then wait 10 seconds before reconnecting it.
• If the 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 Series storage. Please consider formatting the drive as HFS+ Journaled with a Striped or Mirrored RAID Set. See Formatting. Additionally, Time Machine is only compatible with disks formatted in HFS+ or HFS+Journaled. Reformat the drive for Time Machine compatibility

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

A: Disk space will not be reclaimed until the file is 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: After formatting, the available capacity of a drive will show less than advertised on the box. The difference is based upon how capacity is viewed by the operating system. For example, a hard drive that can store 500,000,000,000 bytes is divided by 1,000,000,000 to equal 500GB. This is the actual capacity listed on the manufacturer’s box. The operating system uses slightly different math, dividing 500,000,000,000 by 1,073,741,824 to equal 466GB.

A: Please see Apple Support for instructions on rebuilding a Mirrored RAID Set.
