LaCie Setup Assistant steps

The LaCie Setup Assistant guides you through formatting and registering your hard drive as well as installing LaCie software utilities. Follow the onscreen prompts to complete the setup.

Alternatively, you can use your computer's native disk utility program to format or partition your LaCie drive. See Optional Formatting and Partitioning for details.

  Important info for Mac users: You may be prompted to enter your computer password to continue with LaCie Setup Assistant.
  Important info for Windows users: While running LaCie Setup Assistant, generic pop-up windows may ask if you wish to change your computer's settings. This is a normal request when formatting a hard drive or installing software. To successfully complete LaCie Setup Assistant, please agree to change the settings.

To install software utilities after the initial installation, you can run LaCie Setup Assistant again. Since the format is complete you are only prompted to choose software utilities. LaCie Setup Assistant is available on:
