Frequently Asked Questions

For help setting up and using your LaCie hard drive, review the frequently asked questions below. For additional support resources, go to LaCie customer support.

Hard drive icon

Why does the hard drive icon not appear on my desktop (Mac)?

Is your Finder configured to hide hard drives on the desktop?

Go to Finder and then check Preferences > General tab > Show these items on the desktop. Confirm that Hard Disks is selected.

Is your hard drive mounting in the operating system?

Open Disk Utility at Go > Utilities > Disk Utility. If the hard drive is listed in the left-hand column, check your Finder preferences to see why it is not displayed on the desktop (review the question above).

Does your computer’s configuration meet the minimum system requirements for use with this hard drive?

For detailed information on supported operating systems, please see the following knowledge base article.

Did you follow the correct installation steps for your operating system?

Review the installation steps in Getting Connected.

Why does the hard drive icon not appear in Computer (Windows)?

Is the hard drive listed in Device Manager?

All drives appear in at least one place in Device Manager.

Type Device Manager in Search to launch it. Look in the Disk Drives section and, if necessary, click the Plus (+) icon to view the full list of devices. If you’re uncertain that your drive is listed, safely unplug it and then reconnect it. The entry that changes is your LaCie hard drive.

Is your hard drive listed next to an unusual icon?

Windows Device Manager usually provides information about failures with peripherals. While the Device Manager can assist with troubleshooting most problems, it may not display the exact cause or provide a precise solution.

An unusual icon next to the hard drive can reveal a problem. For example, instead of the normal icon based on the type of device, it has an exclamation point, question mark or an X. Right click this icon and then choose Properties. The General tab provides a potential reason why the device is not working as expected.

File transfers

Why are my file transfers slow?

Are both ends of the USB cable firmly attached?

Review troubleshooting tips for cable connections below:

  • Check both ends of the USB cable and make sure that they are fully seated in their respective ports.
  • Try disconnecting the cable, waiting 10 seconds, and then reconnecting it.
  • Try a different USB cable.
Are there other USB devices connected to the same port or hub?

Disconnect other USB devices and see if the hard drive’s performance improves.

File transfer error messages

Why did I get an error message telling me that the drive has been disconnected when coming out of sleep mode?

Ignore this message since the drive remounts on the desktop despite the pop-up. LaCie drives conserve power by spinning down when you set your computer to sleep mode. When the computer awakes from sleep mode, the drive may not have enough time to spin up, causing the pop-up to appear.

Why did I get an “Error -50” message while copying to a FAT32 volume?

When copying files or folders from a computer to a FAT32 volume, certain characters in the names cannot be copied. These characters include, but are not limited to: ? < > / \ :

Check your files and folders to ensure that these characters are not in the names.

If this is a recurring problem or you cannot find files with incompatible characters, consider reformatting the drive to NTFS (Windows users) or HFS+ (Mac users). See Optional Formatting and Partitioning.

Using a USB hub for USB devices

Can I use my hard drive with a USB hub?

Yes, the hard drive can be connected to a USB hub. If you use a hub and encounter detection problems, slower than normal transfer rates, random disconnection from your computer or other unusual issues, try connecting the hard drive directly to the computer’s USB port.

Some USB hubs are less than efficient with power management, which can be problematic for connected devices. In such a case, you may have to use LaCie Rugged RAID Pro’s included power supply or consider substituting a powered USB hub with its own power cable.

Provided USB cable

Can I use my hard drive with a longer cable?

Yes, provided it is certified according to USB standards. However, LaCie recommends using the cable shipped with your hard drive for the best results. If you use a longer cable and experience problems with detection, transfer rates or disconnection, use the original cable included with your hard drive.

USB 3.0 ports

Will my hard drive’s USB 3.1 Gen 1 port work with my computer’s USB 3.0 (Type A) port?

Yes, the device is compatible with USB 3.0 ports, however, the product does not include a cable with a USB Type A connector. Transfer rates are much slower with USB 3.0.
