seen via the LED. The LED is labeled as “LED 
1” and is located to the right of “Access 2” 
and “Access 1.” The visual representation of 
the progress on all Disk Jockey modes (where 
applicable) can be viewed based on the following 
chart:
5.  At the end of the Disk Check Mode the buzzer 
will sound signaling completion and the LED will 
continue to stay on, 3 seconds later power will be 
turned off automatically.
MODE 6 AND MODE 7 (DATA ERASE X1, X3)
Mode’s 6 and 7 are Data Erase x1 (one pass) and Data 
Erase x3 (three pass) respectively. These two modes 
have been grouped together because the operation and 
explanation of the modes is identical except for the fact 
that the Data Erase x3 (three pass) complete three passes 
of writing zeros to the hard disk drive. Data that had 
previously been written to a disk that has been erased 
using the Data Erase x3 cannot be easily recovered. The 
Data Erase x1 (1 pass) is also often referred to as a “quick 
erase.”
NOTE – the Data Erase x3 will take three times as long to 
complete as the Data Erase x1 as the hard disk drive(s) are 
literally being erased three separate times. 
In Disk Erase Mode the Disk Jockey IS NOT connected to 
the computer.
