Tutorial Guide: 
V.  Load Master Disc onto the Hard Drive   
In order to copy from the Hard Drive, you are required to load your 
master disc onto a hard drive partition. 
The number of partitions the hard drive can hold is determined 
by the capacity of your hard drive and the size of the partitions 
you created. 
For example, if you have an 80GB Hard Drive with a system 
capacity of 74GB.* You can load 74 CDs or 19 DVDs (given a 
4GB average capacity). 
*There are many factors that could contribute to the capacity 
difference between the advertised capacity and the actual 
capacity: 
1. Hard Drive Manufactures use conversion rate of 1GB = 1 
Billion Bytes or 1000^3 Bytes. However, most Operating 
Systems, including our Duplication System use standard 
conversion rate of 1GB = 1.074 Billion Bytes or 1024^3 
Bytes. Therefore, for an advertised 80GB Hard Drive (80 
Billion Bytes), the Duplication System capacity is actually 
74.5 Billion Bytes (74.5GB). 
2. In addition, we round off all fractions of a GB to the lower 
whole number. That means for a hard drive that has a 74.5GB 
system capacity, we only recognize and utilize 74GB. 
The following steps will show you how to load your master disc 
into the installed Hard Drive as a partition and copy the stored 
partition onto blank discs. This process is recommended for mass 
volume production.
