FAQs for Mac Users:
Q: I'm using a USB connection on a Mac. Do I need to
install the USB 2.0 Installation CD?
A: No, the External Hard Drive uses the built-in Mac USB
Mass Storage Support software, which includes the nec-
essary system extensions. However, to use the External
Hard Drive you must have USB Mass Storage Support ver-
sion 1.3.5 or later. You can download the latest update at
http://docs.info.apple.com/article.html?artnum=60394.
Please note: Mac OS 9 does not support USB 2.0, so if
using Mac OS 9, the Drive will operate at USB 1.x speeds.
Q: When I connected the Drive to my computer and
turned it on, I got the following alert message: "Please
insert disk 'untitled'."
A: If you get this alert message, your Mac is not recogniz-
ing your Drive, and the mouse cursor may actually freeze
on screen. If this happens, hold down the Apple/Control
key and press the Period "." key. You should regain control
of your mouse. Restart your computer and rebuild the
Desktop. (Refer to the manual that came with your Mac for
instructions on how to rebuild the Desktop. It is good prac-
tice to periodically rebuilt the Desktop anyway.) After your
Mac reboots, the Drive should mount normally and you
should not have this problem again.
Q: My computer does not recognize the Drive.
A: First, check to make sure that all of your connections
are secure. Then check if your External Hard Drive is listed
in the Apple System Profiler. If the driver listed is "USB
Authoring Support" or "Toast USB Support", disable this
Extension(s) in the Extensions Manager. These Extensions
can cause a conflict with the Drive.
