6 Setup
6.1 Copy Area
This option allows you to select the area on the source device to copy onto the target
devices. You may select either “Only Data Area” to skip all the unoccupied area on the
source device or “Whole Media”.
6.1.1 System and Files
6.1.2 Whole Media
When selected, the duplicator copies the entire content on the source device,
including both the data and empty spaces. This option is used when you
have a source device with unknown file format. For instance a source device
has 2GB capacity; 50MB of data and unknown file format, the duplicator will
copy the whole 2GB of content to target device.
6.2 Asynchronous Mode
Select enable or disable Asynchronous Copy Mode. If the option is enabled, the
duplicator will activate Asynchronous mode automatically when the source device is
inserted into source channel regardless of the file size. The data will be read from
source into the system memory to speed up the copy process. When a target device is
inserted into a target channel, it will start copy process for this target device
immediately, so there is no waiting time for other target device to be inserted and get
ready. If this option is disabled, the duplicator will default to Synchronous copy mode,
and have to wait for all target devices to be inserted in order to start copy at same
time.
6.3 Smaller Target
If the capacity of the target device is smaller than the source device the duplicator can
only partly copy or cannot copy.
The duplicator first analyzes the file format of source device. You may copy
only the system and files area to save overall copy time if the file format is
FAT16, FAT32, NTFS or Linux (Ext2, Ext3). Otherwise, the duplicator will copy
the entire source device content to the target devices including unoccupied
space. For instance, the source device has 2GB capacity but with only 50MB
of data in FAT32 file format. The duplicator will copy only the 50MB of data
area to the target device, hence shortening overall copy time.
