3.3.2 Standard Features
The SuperDuper product supports the following features:
● Automatically discovers the source drive (ATA/SATA).
● Automatically discovers up to a maximum of 8 target drives (ATA/SATA).
● Automatically configures itself for the smallest size target drive.
● Automatically configures itself for the lowest speed target drive.
● Provides both a Button Control Panel and a Serial Port interface.
● Provides the ability to simultaneous transfer data from the source drive to
each of the 8 target drives with no performance degradation.
● Displays the operating status and drive state to a 4 line LCD display.
● Indicates the current operating status using both a status light and buzzer.
● Deactivates a failing target drive without interrupting the other drives.
● Automatically senses the presence of a HPA/DCO on each of the drives.
● Clones the source drive by doing a sector-by-sector copy of the entire
source drive to each of the target drives simultaneously. In addition, it
calculates a SHA-256 hash on the contents of the source drive which can
later be used to verify the data on each of the target drives.
● Verifies that the data has been transferred correctly by simultaneously
calculating a SHA-256 hash on all drives and comparing the resulting hash
value of each target drive with the hash value of the source drive.
● Writes an all zeros data pattern to each of the target drives simultaneously.
3.3.3 User Interface
The user interface for the SuperDuper Hard Drive Duplicating Unit supports both
a LCD (4 line x 20 character) and a serial port. Input is taken through either a
button control panel or a keyboard via a terminal connected to the serial port.
The status information is always displayed to both the LCD and the serial
terminal when connected The following is displayed on the LCD:
● The SuperDuper software version
● The operating state (e.g., Initializing, Ready, Busy, etc.)
● The number of bytes that have been written
● A list of drives, both Active and Disabled
The SuperDuper is designed to disable a target drive whenever a write error is
encountered. Disabling a failing drive does not effect any of the other target
drives and the operation will continue. Whenever a target drive is deactivated,
the failing drive is added to the failed drive list (e.g., Drives: 1234568 F: 7
indicates that drive 7 has failed) which is displayed on the LCD. In addition, the
buzzer will sound each time the light mounted on the unit blinks, to indicate that a
drive has failed. If all of the drives are deactivated, the LCD will indicate that all
drives have failed and the status light will blink fast .
The following table illustrates the status conditions that will be displayed on the
LCD following the execution of each command:
