There are several software packages available that offer a
suite of disk management utilities, including defragmenta-
tion, optimization, repair, erased file recovery and more.
How often you should perform maintenance operations
depends on how much you use the drive. Generally speak-
ing, you should defrag and optimize a drive once every two
or three months, while it's a good idea to examine a disk for
damage at least once a month.
Some disk maintenance and repair operations can take
quite some time, so it is wise to schedule these operations
for those times when you don't need to use your computer.
The good news is that, for the most part, you won't need
to tend to the computer while the software performs these
operations.
Cleaning the Drive Case
Always unplug the power cord before cleaning the Drive.
Clean the Drive using a soft, dry cloth. For tough dirt,
dampen a soft cloth with some neutral detergent diluted
in 5 to 6 parts water; wipe off the dirt, then wipe off the
Drive with a dry cloth. Do not use alcohol, paint thinner, or
other chemicals; they may damage the case surface.

FAQs for All Users:
Q: Why is the capacity of my drive as shown in Windows
or Mac OS lower than the Drive's actual stated capacity?
A: The difference is mostly due to the different way which
Windows and Mac operating systems typically measure
hard drive capacity, as compared to the method used by
hard drive manufacturers.
Hard drive manufacturers have always used the simpler
decimal (base 10) method, where 1GB = 1,000 MB =
1,000,000 KB = 1,000,000,000 bytes. Windows and
Mac operating systems typically use the binary (base 2)
method, where 1GB = 1,024 MB = 1,048,576 KB =
1,073,741,824 bytes.
Example: A hard drive with a capacity of 120 GB will
show up on Windows and Mac with a capacity of around
111.8 GB. The actual number of available bytes is
120,044,335,923, which is just over 120 GB (decimal).
Hard drive manufacturers use the decimal method because
it is simpler and less confusing to consumers who may not
be familiar with the base 2 number system. Manufacturers
of operating systems do not need to concern themselves
with this issue, so they typically use the more traditional
binary method. As long as the drive displays the correct
number of bytes (approximately), you are getting the drive's
full capacity. The reason we say that the number of bytes
will be approximate is because operating systems reserve
a small amount of disk space for their own purposes. The
actual amount may vary depending on the operating sys-
tem.
