Error messages under
Mac OS 10.x.
Did you get an “Error –50” mes-
sage while copying to a FAT 32
volume?
When copying files or folders from Mac OS 10.x to a FAT 32 volume,
file names with 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.
Did you get an error message
telling you that the drive has been
disconnected when coming out of
sleep mode?
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 “revived” from sleep, it does
not give the drive enough time to spin up from its sleep mode.
The drive is working
slowly.
Are there other USB devices con-
nected to the same port or hub?
Disconnect any other USB devices and see if the drive’s performance
increases.
The drive is not running
noticeably faster when
connected via Hi-Speed
USB 2.0.
Are you operating in Mac OS
10.x?
Make sure that you are connecting the drive to your computer through
a Hi-Speed USB 2.0 port. If your computer only has USB 1.0, , you
will need to add a Hi-Speed USB 2.0 PCI or PC card to your com-
puter in order to achieve maximum transfer speeds.
