File transfer error messages
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.
Are both ends of the USB cable firmly attached?
Is the hard drive connected to a Hi-Speed USB 2.0 port on your computer or hub?
Are there other USB devices connected to the same port or hub?
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.
If your hard drive is connected to a Hi-Speed 2.0 port or hub, the inferior performance is normal.
LaCie d2 Professional performance will improve when it is connected to a USB 3.1 port or a
SuperSpeed USB 3.0 port. Otherwise, the device operates at slower USB transfer rates.
Disconnect other USB devices and see if the hard drive’s performance improves.
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.
