Problem

Question

Solution

The drive is not running 
noticeably faster when 
connected via Hi-Speed 
USB 2.0.

Are there other USB devices con-
nected to the same port or hub?

Disconnect any other USB devices and see if the drive’s perfor-
mance improves.

Is the drive connected to a USB hub?

A Hi-Speed USB 2.0 device can only operate at Hi-Speed USB 2.0 
speeds if it is connected to a Hi-Speed USB 2.0 port or hub. Make 
sure your USB hub supports Hi-Speed USB 2.0.

Is the drive connected to a Hi-Speed 
USB 2.0 port on your computer?

Make sure that the Hi-Speed USB 2.0 drivers for both your host 
bus adapter and device have been installed correctly. If in doubt, 
uninstall the drivers and re-install them.

Does your computer or operating 
system support Hi-Speed USB 2.0?

See

Is the drive connected directly to the 
host computer?

Make sure that your drive is connected directly to the computer (see 

 for more information). 

For best performance, connect devices directly to the computer. For

Are you receiving buffer underrun 
errors (has something interrupted the 
stream of data to the recorder)?

For the best recordings, follow these tips to avoid buffer underrun 
interruptions:

 

✦

Quit all other running software programs before starting to 
record.

 

✦

De-activate File Sharing if it is active.

 

✦

If you are making a direct recording, such as a copy, from a 
CD or a DVD, make sure that the speed of the drive playing 
the CD or DVD is fast enough to provide a sufficient data 
stream to the LaCie drive. When making copies, it is recom-
mended that you transfer the material to be copied to your 
hard drive, and then make the recording from the data on 
the hard drive.

 

✦

Reduce the write speed of the LaCie drive using the appropri-
ate menu in the recording software.
