Making Hard Drive-to-Disc Copies
Copying from the hard drive is the best way to make copies. Overall, there
are four benefits to copying from the hard drive.
■
Performance
. Duplicating from the hard drive will greatly boost the
duplication performance.
■
Stability
. Duplicating from the hard drive will stabilize the duplica-
tion process as compared to disc-to-disc duplicating.
■
Durability
. The hard drive is a much better storage device than DVD
recordable discs. The recording surface of a CD/DVD disc is exposed
and can very easily be scratched on its surface, while hard drives are
covered with metal and mounted inside the duplicator.
■
Convenience
. With your master discs stored inside the hard drive,
you can have access to each one easily. There is no need to carry
your master discs; they are all stored inside the duplicator.
NOTE:
In this tutorial, the term partition(s) is also used to
refer to image files in the hard drive.
A partition will be created when you begin to load to a master disc image
into the hard drive. The number of partitions the hard drive can hold is de-
termined by the capacity of your hard drive and the size of the partitions
you create.
Note: Hard drive manufacturers use conversion rates of 1 Gi-
gabyte = 1 billion bytes or 1000^3 bytes. However, most oper-
ating systems, including our duplication system use standard
conversion rates of 1 Gigabyte = 1.074 billion bytes or 1024^3
bytes. Therefore, for an advertised 80 Gigabyte hard drive (80
billion bytes), the duplication system capacity is actually 74.5
billion bytes (74.5 Gigabytes).
The following steps will show you how to load your master disc into the in-
stalled hard drive as a partition and copy the stored partition onto blank
discs. This process is recommended for mass volume production.
A master disc image can be loaded onto the hard drive from one of two
ways:
■
It can be loaded into a disc image by reading the master disc from
one of the CD-ROM/DVD drives (usually the reader Drive)
■
It can be written to the duplicator from an external PC over the USB
connection.
Note:
The Xerox Duplicator USB Installation Utility must be
installed.
