Heat Dissipation Design

The Thunderbolt Series enclosures feature metal bodies that dissipate drive heat. The large surface area of the heat sink casing absorbs all internal heat, keeping the drives safe and prolonging their life. Since LaCie's unique design draws heat away from the internal drives, the external casing will be warm to the touch after extended use. Please make sure that the vent on the back bezel is not obstructed and that there is a natural airflow across the casing.

Thunderbolt Technology and Daisy Chain

Thunderbolt Technology

Thunderbolt technology is an active cable technology with extraordinary promise. A single Thunderbolt technology connection includes two bi-directional streams, each with a potential bandwidth of up to 10Gb/s. As the illustration demonstrates, the streams run in opposite directions to support simultaneous operations: one bi-directional stream for data operations and another bi-directional stream for video operations. For example, files can be copied to the Thunderbolt Series volume (upstream) while playing back an HD film on your computer (downstream). Certainly, it is possible to perform both actions with existing interface technologies but not at the speeds offered by a Thunderbolt technology connection. See the performance comparison in the illustration.

While maximum theoretical transfer rates are rarely sustained, it is no less impressive to imagine the amount of high-end data that can be passed to and from your LaCie Thunderbolt Series storage. To take advantage of the throughput offered by Thunderbolt technology, the two internal drives in your LaCie enclosure have been preconfigured as a Striped RAID Set (RAID 0).


Daisy Chain

The back of your Thunderbolt Series enclosure features two Thunderbolt technology ports for:

  • Direct connection to a Thunderbolt technology compatible Macintosh computer
  • Daisy chaining Thunderbolt compatible devices and displays

Connect the cable to one of the interface ports on the back of your LaCie Thunderbolt Series enclosure and to your Macintosh computer. The additional port may be used to daisy chain compatible computer peripherals, such as hard drives, monitors, and much more. A single Thunderbolt technology line can have seven devices, including the computer.

Important cable info: When connecting your Thunderbolt Series enclosure to a computer or compatible devices, please use cables specifically constructed to support Thunderbolt technology. Go to for further information.

Important info: The Thunderbolt Series enclosure must be connected to a Macintosh computer that supports Thunderbolt technology. While the ports on the back of the device can easily seat Mini DisplayPort cable ends for daisy chaining displays, the Thunderbolt Series storage will only work when connected:

  • To a computer that supports Thunderbolt technology.
  • To a computer with a cable that supports Thunderbolt technology.


Getting Connected

Please follow the setup steps in the order they are given to ensure that the Thunderbolt Series volume mounts correctly on your computer.

Connect the Interface Cable

  1. Connect a cable that supports Thunderbolt technology to one of the enclosure's Thunderbolt ports. Plug the other end of the cable to a compatible Thunderbolt technology port on your Macintosh computer. The additional interface port on the Thunderbolt Series enclosure may be used to daisy chain compatible devices and displays.
    Little Big Disk

  2. Connect the included external power supply to an outlet and to the enclosure power port.
    Little Big Disk

  3. The device will turn on automatically when it receives power and the volume will mount on the desktop.
    Little Big Disk

Technical note: A single Thunderbolt technology daisy chain can have seven devices, including the computer.


Unmounting the Thunderbolt Series Volume

In order to avoid file system corruption, it is important to unmount the volume(s) before turning off the enclosure or disconnecting the interface cable. See Unmounting Your Drive for details.


Install Drivers (Windows Only)

Supported operating systems:

  • Windows 7
  • Windows 8

Windows users must install a special driver on their computers in order to use the Thunderbolt connection. Once the driver is installed, users can prepare the disks and RAID for a Windows environment.

Important info regarding RAID and Windows: RAID 0 and RAID 1 are available on the following versions of Windows:

  • Windows 7 Professional/Enterprise/Ultimate
  • Windows 8 and Windows 8 Pro

RAID cannot be configured using Windows 7 Standard and Home editions.

Important info regarding RAID and double-byte characters: RAID cannot be configured using a computer with double-byte characters in its name. This is often the case when using Chinese, Korean, and Japanese fonts. To configure RAID, use a name that contains only single-byte characters.

To download the installer for the LaCie Thunderbolt driver, please select your product below:

Order of operations: Please follow the order of operations as listed below. You must install the drivers BEFORE connecting the LaCie Thunderbolt device to your Windows computer.

Part 1

  1. Unzip the installer downloaded from LaCie.
  2. Double-click the executable file.
  3. Follow the steps to complete the wizard.

  4. When prompted, restart your computer.
  5. Move on to Part 2.

Part 2

Since this LaCie product is originally configured in the HFS+ file format (for use on Mac) and RAID 0, all partitions must be erased, including the EFI partition. Windows Disk Management cannot erase the EFI partition so you'll need to run Diskpart, a separate Windows utility. For additional information on Diskpart, please click here.

Important info: The operation below is data destructive. Before continuing, LaCie recommends that you:

  • Confirm that your Windows computer is compatible with Thunderbolt technology.
  • Back up all files stored on your LaCie Thunderbolt device (if applicable). Please connect your LaCie Thunderbolt device to a Mac with a Thunderbolt port to back up your data.
  • Disconnect all external disks from your Windows computer except for the LaCie Thunderbolt device. While Diskpart will not allow you to delete the System disk, selecting another external hard drive connected to your computer will delete all of its files. LaCie is not responsible for lost data.

The steps below are illustrated using a LaCie Little Big Disk, which contains two hard disks.

  1. Connect the LaCie product to your compatible Windows computer via the Thunderbolt cable. If necessary, turn the device on.
  2. Click on the Windows Start button.
  3. Search for and launch Diskpart.

  4. In the Diskpart prompt, type list disk.

  5. Since the RAID was configured on a Mac, the LaCie disk partitions appear as Foreign (Disks in non-RAID configurations may appear as Online rather than Foreign). In this example, the first Foreign hard drive is Disk 1. The disk numbers will be different on Windows computers with more than one internal hard drive. Please make certain to locate the disk number(s) for your LaCie device then type select disk n. n is the number for the first LaCie hard drive, 1 in the screenshot below.

  6. Diskpart will confirm that your hard disk has been selected.

  7. To delete all paritions on the hard disk, type clean.

  8. Diskpart will confirm that your hard disk is clean, meaning that the partitions have been deleted.

  9. Repeat steps 5-8 for the remaining hard disks in your LaCie Thunderbolt device.

  10. Once all the HFS+ partitions have been deleted, close Diskpart then move on to Part 3.

Part 3

If you successfully completed Part 2, then your LaCie Thunderbolt storage currently has no RAID set up. In Part 3, you'll set up a RAID array using Windows Disk Management.

  1. Right-click on Computer and choose Manage. From the Manage menu, select Disk Management.
  2. A prompt may ask you to initialize new disks. This is normal following the use of Diskpart. Click OK.

  3. Each of your LaCie Thunderbolt device's disks will be represented with a row in the lower part of the window. They should be labelled as Unallocated. Right-click on the first disk's row and select New Striped Volume (RAID 0) or New Mirrored Volume (RAID 1).

  4. The New Striped Volume wizard or the New Mirrored Volume wizard will open. Click Next >.
  5. Select the disk(s) you wish to add to the array and click the Add > button. Click Next > once all disks have been added.

  6. Assign the volume a drive letter, then click Next >.

  7. Name the volume and assign a file system (usually NTFS), then click Next >. To expedite the RAID configuration, keep the box checked next to Perform a quick format.

  8. Review the summary in the next window then click Finish to format the hard disks.
  9. A prompt will ask you to confirm the conversion of the disks from basic to dynamic. Click Yes to continue.
  10. The volume will mount on your computer. If you created a mirrored (RAID 1) volume, it will take some time for the OS to sync the drives. However, the volume is immediately accessible.

Important info: If you wish to remove LaCie RAID Monitor from your computer, please run the Uninstaller. Dragging the program icon to the Trash will not completely remove the utility from your computer.

Replacing a Disk (2big)

Important info: While all Thunderbolt Series users should contact LaCie Customer Support if disk failure is suspected, this section pertains to the 2big only due to the type of enclosure.

In the event that an individual hard disk fails in the LaCie 2big Thunderbolt Series, please contact your LaCie reseller or LaCie Customer Support. Failed hard drives within the 2big Thunderbolt Series enclosure should only be replaced by a compatible LaCie disk with equal capacity.

Once you have received your replacement disk, follow the steps below for proper installation.

Caution: After continuous use of the LaCie 2big Thunderbolt Series, drives may be hot. Please use caution when removing the disks.

To Remove a Disk

  1. Confirm that the 2big Thunderbolt Series enclosure is off.
  2. Please make certain that you are properly grounded to avoid electrostatic discharge.
  3. The drive tray may be locked. To unlock it, insert the round end of the included 2-in-1 tool into the slot on the drive lock. Turn the lock until the slot is vertical.
    2-in-1 Tool

  1. Draw out the drive tray by inserting your finger into the space behind the drive tray handle and pulling to disengage the drive.
  2. Grasp the drive tray handle and carefully extract the drive.

Important info: LaCie highly recommends replacing the disk that has been removed as soon as possible.

To Insert a Disk

  1. Confirm that the 2big Thunderbolt Series enclosure is off.
  2. Remove the failed disk according to the instructions above. Please make certain that you are properly grounded to avoid electrostatic discharge.
  3. Remove the screws from the drive tray to replace the failed drive with the disk that you received from LaCie.
  4. Fasten the screws back on the drive tray.
  5. Carefully insert the drive tray into the empty disk bay. When the drive tray is almost flush, you will feel a bit of resistance. Press the drive tray handle firmly until the drive snaps into place and it is in line with the back pane of the 2big Thunderbolt Series.
  6. Use the 2-in-1 tool to fasten the drive lock. The drive is locked when the line is in a horizontal position.

Rebuilding a RAID Set

Striped RAID Set (RAID 0)

Once the replacement disk is installed in the 2big enclosure, go to Formatting for instructions on building a Striped RAID Set.

Mirrored RAID Set (RAID 1)

The 2big Thunderbolt Series RAID is configured using Mac Disk Utility. Please visit the Apple® Support page for instructions on how to recover from a hard drive failure on a mirrored array (Apple Support).

Important info: LaCie recommends that you do not remove one or both disks in a healthy Mirrored RAID Set. Removing a healthy drive may force you to rebuild the Mirrored RAID.



The two drives within the 2big Thunderbolt Series and the Little Big Disk Thunderbolt Series are pre-formatted as HFS+ Journaled for your Macintosh computer. Further, the disks have been preconfigured as a Striped RAID Set (RAID 0) for optimal performance.

Important info:

You have the option to adjust the RAID configuration as a Mirrored RAID Set for data protection using the Mac OS X Disk Utility. Please note that a Mirrored RAID Set copies the same files to each disk, affecting the transfer rate speed and reducing the available disk capacity by half.

Striped RAID Set (RAID 0)

A Striped RAID Set pairs the two drives within the enclosure for enhanced transfer rates. Data is stored across both disks in a striped pair, allowing them to share the demands of reading and writing files. Unlike a Mirrored Striped Set (RAID 1), the available capacities of each disk are added together for maximum storage availability.

With its improved read/write seek rates and maximum storage capacity, a Striped RAID Set is a great complement to the extraordinary performance already offered by the Thunderbolt technology. Data is easy to access since a stripe creates one logical volume that mounts on the desktop.

One disadvantage of a Striped RAID Set is the lack of built-in data security. In the event that one disk fails, all the files become inaccessible since parts of each string of data are written across the striped pair. Therefore, LaCie highly recommends backing up data stored on a Striped RAID Set at least once a day. You can back up the data to your computer’s internal disk or another hard drive with sufficient capacity.

Mirrored RAID Set (RAID 1)

In a Mirrored RAID Set, the two physical disks are mirrored together so that one single logical volume mounts on the desktop. Please note that the combined storage will not exceed the available capacity of the lowest-capacity single disk. All data is saved simultaneously on each disk which means that files will not be lost if one drive should fail.

Important info: LaCie recommends that you do not remove one or both disks in a healthy Mirrored RAID Set. Removing a healthy drive may force you to rebuild the Mirrored RAID. For further information on rebuilding a Mirrored RAID Set using Apple Disk Utility, please go to Apple Support.


Configuring a RAID Set

Important info: LaCie Thunderbolt Series enclosures are plug and play storage pre-configured in RAID 0. To use the disks out of the box, see Getting Connected for information on connecting your device to a Macintosh computer that supports Thunderbolt technology.

Follow the directions below when reformatting the Thunderbolt Series hard drives.

  1. Connect the LaCie Thunderbolt Series enclosure to your compatible Macintosh computer.
  2. The drives will appear on the desktop as a single icon if they are still configured as a Striped RAID Set or individual icons if they have been reformatted.
  3. Go to the pulldown menu Go > Utilities.
  4. The Utilities window will open. Click twice on the application Disk
  5. The drives are listed on the left side of the Disk Utility window.
  6. Click on one of the LaCie drives to see the action tabs. Click the RAID tab.
  7. The RAID tab includes three important settings: RAID Set Name, Format, and RAID Type.
  8. Clicking on the Format pulldown menu shows the file system formats available for the drives when creating the RAID. Select Mac OS Extended (Journaled).
  9. Clicking on the RAID Type pulldown shows the available RAID configurations. LaCie highly recommends that you select Striped RAID Set for enhanced performance. For data protection, choose Mirrored RAID Set.
  10. Fill in a name for your Striped or Mirrored RAID Set in the field RAID Set Name.
  11. Drag one of the drives to the empty field in the middle of the RAID tab.
  12. Drag the second drive to the same field in the middle of the RAID tab.
  13. To change the RAID Block Size, click the Options… button on bottom of the window. While this example shows the default, you may want to choose a higher RAID Block Size if you will be working with larger files (i.e. high-end video and audio). Please see your software's user manual for the recommended RAID Block Size. Once you have chosen a RAID Block Size, click OK.
  14. Click Create on the bottom of the window to begin building the RAID.
  15. Click Create in the pop-up window.
  16. Please be patient while Disk Utility configures the RAID. The RAID Set will appear on the desktop as a single drive icon.
