User guide

copy from a master card, you can choose whether the PowerSoftware should try to create a short
image file. This is only possible if the medium has a FAT16 or FAT32 file system and is only
meaningful if the master medium is not full of data. See chapter 4.3.1 for more information on short
image files.
Generally speaking, it is faster to copy internally (from the master to memory cards in the other
slots) than it is to transfer an image file via USB 2.0 to the CopyStation during the copy process. In
addition, if you have connected several IQ CopyStations to the PC they share the bandwidth of the
USB controller which can further reduce the copy speed if you copy from an image file on the PC
(explanation: the PC’s USB ports are generally assigned to one or at most two USB controllers.
The USB controllers share the entire available bandwidth dynamically among all of the USB ports -
the principle of the logical bus structure). However, if you want to copy to a large number of cards
(at least 22), the potential speed disadvantages of copying from image files can be avoided with
the option “First fill master and then use it as source”on the Flow Control tab.
If you copy from an image file which has been created with an MD5 checksum and you want to
verify the file before copying, check the “Use MD5 checksum” checkbox. The MD5 checksum
allows the PowerSoftware to check whether the image file has been changed since it was created.
Attention: This test does not test the correctness of the copied data on the destination media!
