Problem: The drive isn't appearing on my computer.
Q: Are you connecting the product to a host computer via the Thunderbolt interface, and have not installed Thunderbolt
drivers?
A: Drivers are required for the Thunderbolt interface. Disconnect the Thunderbolt cable and attach the USB
cable. To install drivers, follow the steps in
Install Drivers (Windows Only)
. Then disconnect the USB cable and
connect the Thunderbolt cable.
Q: Are both ends of the interface cable securely attached?
A:
Check both ends of the cable to make sure they are fully seated in their respective ports.
■
Try disconnecting the cable then wait 10 seconds before reconnecting it.
■
If the drive is still not recognized, restart your computer and try again.

Q: Is the drive listed in Device Manager?
A: All LaCie drives appear in at least one place in Device Manager.
To access Device Manager, click on Start and select Run from the menu. In Windows Vista, the 'Run' option
doesn't appear by default, so press [Windows-button] and [R] on your keyboard.
Enter the command: devmgmt.msc
Click OK and the Device Manager program will open. For troubleshooting, look in the Disk Drives section. It
might be necessary to click on + on the left side.
If you're not sure if your drive is listed, unplug it, then reconnect it. The entry that changes is your LaCie drive.
Q: Does your disk not appear at all?
A: Proceed to physical troubleshooting topics above.
Q: Is your drive listed next to an unusual icon?
A: Windows Device Manager can usually provide information about failures in accessories. It does not display
the exact cause, or a solution, but it can assist in troubleshooting most problems.
A problematic device can be found by its unusual icon. Instead of the normal icon based on the type of device, it
is instead an exclamation point, question mark, or an X.
Right-click this icon, then choose Properties. The General tab will show why the device is not working.
Still not working? There may be a hardware defect or other problem. Time to contact
