LaCie d2 SATA II 3Gbits
User’s Manual
The Problem
The drive is not
recognized by the
computer.
Error messages under
Mac OS 10.x.
Unplanned shutdown.
Mac OS 10.3.x “hangs”
when you connect a
LaCie Hard Drive.
Questions To Ask
Has the drive been formatted?
Did you hot-plug the drive?
Is there a conflict with other
device drivers or extensions?
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?
Did you have an improper
shutdown, forced restart or
power interruption?
Is the drive formatted as a NTFS
volume?
Possible Solutions
Make sure that the drive has been formatted properly. Please
see sections 4.1. Formatting Your LaCie Drive – Mac Users
and 5.1.1. File System Formats – Mac Users for more
information.
Try restarting the computer with the drive on. Some older
systems and non-LaCie PCI cards may not support hot-plug
functionality.
Contact LaCie Technical Support for help.
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.
If this happens and you are running Mac OS 10.x, you can
utilize Apple’s Disc Utility to check the status of the drive and
recover from such an event. Please refer to Apple’s Web site
article: Mac OS X: About Using Disc Utility and fsck for File
System Management.
If the file cluster size is set at 4KB (which is the default setting
under Windows), this may be too small. Reformat the drive
and change the cluster size to 32KB.
