====== Getting Connected ======

Follow the setup steps in the order they are given to ensure that your LaCie hard drive's volume mounts correctly on your computer.

===== Thunderbolt and Windows =====

<note technical>**Important info:** Thunderbolt technology is compatible with Windows 7 and Windows 8. Windows requires drivers to use the Thunderbolt port. It is recommended that you connect the product to a host computer via USB and run LaCie Setup Assistant (see Step 3 - Launch LaCie Setup Assistant). Once LaCie Setup Assistant is finished, disconnect the LaCie d2 Thunderbolt 2 (see [[unmounting|Unmounting Your Hard Drive]]) from the USB port and install the Thunderbolt drivers for Windows (see [[drivers|Install Drivers (Windows Only)]]). You can connect via the Thunderbolt interface once the drivers are installed.</note>
