To activate the new data storage schedules that have been configured in the SET UP NEW 
SCHEDULES menu requires you to “initialize” the DOS formatted disk to which process and diagnostic 
data will be stored.  This is done by executing a routine entitled INITIALIZE DISK, also found in the 
DATA STORAGE menu.  This task can also be done on a PC. The task of initializing a disk and 
activating data storage schedules are one in the same. 

ATTENTION 

Initializing a disk is only necessary for performing Data Storage.  You do not have to initialize a disk to perform 
Configuration, Set Point Program, or Calibration Storage 

When executing the INITIALIZE DISK menu prompt, you will observe two selections:  USE NEW 
SCHEDULES and USE CURRENT SCHEDULES.  The “SCHEDULES” in both selections refer to the 
data storage schedules prepared in the SET UP NEW SCHEDULES menu described earlier.  USE NEW 
SCHEDULES to initialize the disk to activate a newly configured data storage schedule for the very first 
time. The only time you will USE NEW SCHEDULES again is after you have made any changes to the 
way the data storage schedules have been configured.  You must USE NEW SCHEDULES to initialize 
the disk in order for these changes to take effect.  USE CURRENT SCHEDULES to initialize a disk if the 
disk will replace one that has become full. This will ensure that data being recorded continues 
uninterrupted over the space of both the full and replacement disks. During the time when the full disk is 
being replaced with a new disk, recorded data will be stored to the instrument’s memory buffer.  Upon 
completing initialization via the USE CURRENT SCHEDULES prompt, all buffered data will be written to 
the new disk and data storage will resume, with no lapses of storage between disks. 

Disk initialization allocates sections of the disk to each of the files you have elected to store per the SET 
UP NEW SCHEDULES menu.  Once the instrument completes initializing the disk, process and 
diagnostic data recording begins immediately, indicated by a yellow-colored letter “S” in the lower right 
hand corner of the instrument screen. 

Pre-initializing a ZIP disk on the video recorder takes time, there is a more efficient way to do it : using 
theSDI  tool. The SDI tool is a very basic, straightforward Win 95/98/NT program that can be used to 
quickly pre-initialize a ZIP disk on a PC. This tool is provided with the video recorder. Install it on your 
PC, as per instructions on the floppy disk label. 
Here are the 3 steps to follow when running the SDI utility. 
 

Select the drive letter where the
disk to initialize can be found

Select the number of trend
groups you want to initialize

Click on initialize
