Troubleshooting for Mac users

The power will not go on when I connect the Drive.
A: Make sure your connections are secure. If you are trying
to use bus power, make sure you are using the proper cable
(s). See "Connecting the Drive to Your Computer. "
My computer does not recognize the Drive.
A: First, make sure the connections are secure. Second, check
if your AcomData 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, as they can cause a conflict with the Drive.
When I leave my computer idle for a while and come
back, my AcomData Drive won't work properly.
A: The most likely cause is that your computer is going to
sleep. The immediate solution is to restart your computer.
To prevent this problem from recurring, go into your Energy
Saver preferences and set it to never go into Sleep mode.
The Drive feels warm when powered on. Is this dangerous?
A: When in operation, the Drive may feel quire warm to the
touch. This is normal.
When using a USB 2.0 connection, the Drive seems to be
operating slower than the rated 480 Mbps.
A: First, in order to reach USB 2.0 speeds, you must use a
USB 2.0-compatible connection. If the connection only sup-
ports USB 1.x the Drive will operate at USB 1.x speeds.
Second, 480 Mbps is the maximum rate. Actual data transfer
rates will vary depending on a number of factors, including
available CPU resources.

When I connected the Drive to my computer, I got the fol-
lowing alert message: "Please insert disk 'untitled'."
A: Your Mac is not recognizing your the 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. It is good practice
to periodically rebuilt the Desktop anyway.) After your Mac
re-starts, the AcomData Drive should mount normally and
you should not have this problem again.
I set up my Drive on Mac OS 9. When I upgraded to Mac
OS X my computer asked me to re-initialize the Drive.
A: If this message appears, you have no choice but to re-
initialize (re-format) the Drive in order to use it on Mac OS
X. With the Drive connected to Mac OS 9, copy the data on
the Drive, that you wish to save, to another storage device.
Then, re-initialize the Drive on Mac OS X, and copy the
saved data back to it.
Why is my AcomData Drive asking me to initialize it? It
was already formatted and it contains data.
A: The most likely reason is that the file system has become
corrupted, in which case it needs to be repaired. Use disk
utility software, such as Norton Utilities, to repair the disk.
Periodic testing of a hard drive is recommended to keep it
in good working order.
I can't transfer files larger than 2 GB.
A: This is a limitation of the FAT32 file system. If you plan to
use the Drive on a Mac OS only, consider re-formatting the
AcomData Drive using the Mac OS Extended file system.
