FMCS - DATABASE LOAD 
Load After you put the diskette into the loader, the load process is automatic. Except to change diskettes, no further operation is necessary.  - INCORRECT DISK INSERTED (the diskette does not compare with the diskette you used before). 
CURRENT RECORD shows the number of data base records that are loaded into the FMC data base memory. TOTAL RECORDS show the total number of records to be loaded into the FMC data base memory. 
During the loading process, the message LOAD IN PROGRESS shows. INSERT NEXT DISK shows during multi-disk data base load. 
The load is complete when LOAD COMPLETE shows on the MCDU. Push the eject button on the loader to remove the diskette. 
Load Failure Indications 
If the loader finds a problem, a message shows on the data loader display and DATA LOAD INOP shows on the CDUs. 
If the FMC finds a problem with the data from the loader, the MCDU shows one of these messages: 
-CHECK DBL OR INTERFACE (there is a problem that the FMCS cannot isolate to the FMC or the loader) -DB EXCEEDS FMC (the data on the disk is too large for FMC memory) -RESET COUNT EXCEEDED (five load attempts have failed) -DB-OFP INCOMPATIBLE (the data on the disk does not compare with the FMC operational program) -CHECK MEDIA (part of the data on the disk cannot be read by the loader)
