WARNING: BEFORE EXECUTING THE CONFIGURATOR OR OTHER DIAGNOSTIC SOFTWARE, BE SURE
TO SAVE ALL DIRECTORY INFORMATION & DATA FROM THE MDD. ANY TIME YOU
EXPERIENCE DIFFICULTY WITH THE ODSS AND SUSPECT THAT THE MDD MAY HAVE TO BE
REFORMATTED OR THAT DIAGNOSTICS HAVE TO BE EXECUTED, LOAD AND RUN THE
“SAVEWINCH” PROGRAM IF YOU CANNOT CLOSE THE OPTICAL DISK PLATTER.
IT IS BEST TO CLOSE THE PLATTER (“M” LEVEL) IF AT ALL POSSIBLE. THIS WILL
COMPLETE THE WRITING PATIENT DATA AND DIRECTORY INFORMATION TO THE OPTICAL
DRIVE. IF THE CLOSE PROCEDURE FAILS, THEN USE THE SAVEWINCH PROCEDURE AS
OUTLINED HERE.
WARNING: SAVEWINCH CAN GET YOU INTO TROUBLE. SAVEWINCH MUST ONLY BE USED
IMMEDIATELY PRECEDING SERVICE WORK PERFORMED ON A PLATTER THAT WILL NOT
CLOSE. UNDER NO CIRCUMSTANCES MUST ADDITIONAL PATIENT IMAGES BE STORED TO
OPTICAL DISK AFTER SAVEWINCH HAS BEEN EXECUTED. IF THIS HAPPENS, THE IMAGES,
MAY BE STORED ON THE OPTICAL MEDIA BUT THE FILE “WINCHESTER” WILL NOT BE
UPDATED WITH THE OPTICAL DISK ADDRESS OF THE IMAGES. AFTER THE MDD IS
RESTORED USING THE RESTWINCH PROCEDURE, THE ADDITIONAL IMAGES WILL NOT BE
ABLE TO BE ACCESSED. THIS IS THE SAME AS NOT STORING THE IMAGES IN THE FIRST
PLACE. THEREFORE, ONLY EXECUTE SAVEWINCH IMMEDIATELY PROCEEDING ANY
SERVICE WORK THAT YOU HAVE TO DO. WHEN FINISHED, EXECUTE RESTWINCH TO
RESTORE THE MDD DIRECTORIES ETC.
WARNING: NEVER USE THE CUSTOMERS OPTICAL MEDIA FOR SERVICE PROCEDURES. BEFORE
CHANGING THE MDD OR THE ODD, EXECUTE THE PROGRAM SAVEWINCH AND SAVE THE
FILE “WINCHESTER” TO TAPE. THEN REMOVE THE CUSTOMERS OPTICAL MEDIA AND USE
A SERVICE OPTICAL MEDIA FOR RUNNING DIAGNOSTICS ETC. SAVEWINCH ONLY SAVES
THE DIRECTORY AND ADDRESS ETC. INFORMATION THAT IS STORED ON THE MDD IT
DOES NOT SAVE THE PATIENT IMAGES STORED ON THE OPTICAL MEDIA ITSELF.
THEREFORE, IF YOU RUN SAVEWINCH BUT USE THE CUSTOMER OPTICAL MEDIA TO
EXECUTE DIAGNOSTICS ETC. YOU MAY WRITE INFORMATION TO THE CUSTOMERS
OPTICAL MEDIA AND PREVENT IT
FROM CLOSING (EFFECTIVELY DESTROY ALL
INFORMATION ON IT). AFTER SERVICE IS COMPLETE, LOAD THE FILE WINCHESTER TO
DISK AND EXECUTE THE PROGRAM RESTWINCH TO RESTORE THE CONTENTS OF THE
MDD, REINSTALL THE CUSTOMERS OPTICAL MEDIA, AND THE CUSTOMER CAN RESUME
STORAGE TO THE OPTICAL DISK.
The following procedures “SAVEWINCH and RESTWINCH” should be used when a problem occurs in the
Optical Disk Subsystem that prevents the Optical media from being “CLOSED” (write the directory from the
MDD to the OD media and detaching the OD media). This procedure saves the directory and other information
(not the patient images) to a disk file called “WINCHESTER” in the root directory (DA0 or DZ0) of the system
disk drive. After the ODSS has been repaired or replaced, the directory data contained in the disk file called
‘WINCHESTER” can be reinstalled on the MDD using the program RESTWINCH and the Optical media may
then be closed. It is always best to CLOSE the customers Optical Media prior to servicing the Optical Disk
Subsystem.
Note: Close and Purge mean the same thing. The meaning is to write the directory and other information
contained on the MDD (Magnetic Disk Drive or Winchester) is written to the Optical Media and the
Optical Media is made Read Only. After a platter is closed, it may never be written to again. However,
the information stored on it many times. A Customers Media must always be closed at M level-Never
use the purge program, on the Proprietary tape, to close a customers Media.
