The Issue
Error messages under
Mac OS 10.x.
The drive is working
slowly.
The USB 2.0 drive is
not running noticeably
faster than a USB 1.1
drive.
Questions to Ask
Did you get an Error –50 message
while copying to a FAT 32 volume?
Did you get an error message
telling you that the drive has been
disconnected when coming out of
sleep mode?
Are other USB devices connected to
the same port?
Is the drive connected to a USB 1.1
port on your computer, or to a USB
1.1 hub?
Is the drive connected to a USB 2.0
port on your computer?
Does your computer or operating
system support USB 2.0?
Possible Solutions
When copying files or folders from Mac OS 10.x to a FAT
32 volume, certain characters cannot be copied. These
characters include, but are not limited to:
? < > / \ :
Check your files and folders to ensure that these types of
characters are not being used.
Simply ignore this message. The drive will remount to the
desktop. LaCie drives conserve power by spinning down
when you set your computer to sleep mode, and when the
computer is “woken” from sleep, it does not give the drive
enough time to spin-up from its sleep mode.
Disconnect any other USB devices and see if performance
improves.
If so, it is normal that the drive runs at USB 1.1 speeds. A
USB 2.0 device can only run at USB 2.0 speeds when con-
nected to a USB 2.0 port or hub and controlled by the appro-
priate USB 2.0 drivers.
Check to see that the USB 2.0 drivers for your Host USB
2.0 port and for your USB 2.0 device have been correctly
installed (see the 7.3.1. What Is USB 2.0? section for a more
detailed discussion). If in doubt, uninstall the driver and then
reinstall it.
